Apple Just Released iOS 13 Developer Beta 5 for iPhone

Jul 29, 2019 05:00 PM

Aug 7, 2019 05:59 PM

Beta testing for Apple's big upcoming iPhone update, iOS 13, is well underway. So far, each of the four beta versions we've seen brought new features and changes to the table, many of which were never even mentioned by Apple during WWDC in June. Now, it's time to do it all over again, as Apple just released the fifth developer beta for iOS 13.

Apple also released the fourth public beta for iOS 13 (for AppleSeed participants) alongside dev beta 5. However, the earliest we expected Apple to seed the regular public beta 4 is three hours after the developer version, the company's usual timeframe for public beta releases. That said, Apple is a bit unpredictable when it comes to its public beta cycle.

At this time, it seems dev beta 5 is an incremental update over dev beta 4 and earlier. Here, you'll find bug fixes for issues in the last beta, including fixes for sharing items directly from Mail; audio playback in Instagram stories; duplicate notifications and forwarding messages in WhatsApp; and restoring stability to the Wells Fargo app.

Update: Apple's iOS 13 Developer Beta 6 Available for iPhone

As for new features and changes, the best one comes for iPad, where you can now choose a six-by-five grid for apps on the home screen, compared to the standard four-by-five one. For iPhone, there are new achievements for Move goals in the Activity app if you're an Apple Watch owner; there are more wallpapers in the Home app; the activity view (aka Share sheet) has groupings for basic actions vs. custom actions; and the LTE, 4G, 5Ge icons in the status bar are bigger (same height as battery icon).

Other noteworthy features include being able to disable album art in CarPlay, CarPlay's Now Playing screen is a tiny bit different, there's a "Siri for Everyone" screen that shows if you have HomePodOS 13, and you get haptic feedback when you slide to adjust the volume on the on-screen overlay. Also, the "Automations" tab is gone in Shortcuts but will be back in a future update.

While some might be disappointed by the lack of new features in this update, it seems to be a trend for the latest iOS 13 betas. The volume of changes has dwindled as of late, with dev beta 4 adding the smallest impact.

For those of us who love a proper changelog, Apple posted the release notes for dev beta 5. These notes detail present or fixed bugs as well as new features, especially as they pertain to developers:

iOS & iPadOS 13 Developer Beta 5 Release Notes:
Overview
The iOS & iPadOS 13 SDK provides support for developing apps for iPhone, iPad, and iPod touch devices running iOS & iPadOS 13. The SDK comes bundled with Xcode 11 beta available from Beta Software Downloads. For information on the compatibility requirements for Xcode 11, see Xcode 11 Beta 4 Release Notes.
Developers using iOS 13 beta 5 must also update to Xcode 11 beta 5.
Important
Upgrade your iPhone to the newest available version of iOS 13 beta before upgrading any paired watches to watchOS 6 beta or a newer version of watchOS 6 beta. (51366653)
General - Known Issues
Some automatically detected links such as flight numbers might not open when tapped. (53416463)
Snapshots for apps that use Metal might have an unexpected appearance in the App Switcher. (53121694)
General - Deprecations
The UIApplicationExitsOnSuspend key is no longer supported in iOS & iPadOS 13. Update your apps to handle modern multitasking. (43958234)
Audio - New Features
Voice Processing mode can now be enabled on AVAudioEngine. (50906329)
New AVAudioNode types can be used to wrap a user-defined block for sending or receiving data in real time.
A new method is available for an AVAudioEngine-based app to retrieve a list of all nodes attached to an AVAudioEngine instance.
A new rendering mode in AVAudioEnvironmentNode selects the best spatial audio rendering algorithm automatically based on the output device.
A new AVAudioSession property allows system sounds and haptics to play while the session actively uses audio input.
A new enumeration, AVAudioSession.PromptStyle, informs apps which style of voice prompt they should play based on other audio activity in the system.
AVAudioSession.RouteSharingPolicy now permits apps to specify route-sharing policies so their audio and video routes to the same location as AirPlay.
Audio Unit Extensions now support user presets that are available across all host applications.
Audio - Deprecations
The OpenAL framework is deprecated and remains present for compatibility purposes. Transition to AVAudioEngine for spatial audio functionality.
AUGraph is deprecated in favor of AVAudioEngine.
Inter-App audio is deprecated. Use Audio Units for this functionality moving forward.
Carbon component-based Audio Units are deprecated and support will be removed in a future release.
Legacy Core Audio HAL audio hardware plug-ins are no longer supported. Use audio server plug-ins for audio drivers moving forward.
Audio Sharing - New Features
Audio sharing is compatible with AirPods (1st generation or later) and PowerBeats Pro. iPhone 8 or later, iPad Pro 12.9-inch (2nd generation or later), iPad Pro 11-inch, iPad Pro 10.5-inch, iPad (5th generation or later), iPad Air (3rd generation), iPad mini (5th generation), or iPod touch (7th generation or later) is required. (51331268)
AVFoundation - New Features
AVFoundation now supports encoding video with alpha channels using HEVC. Videos encoded in this manner are broadly supported in AVFoundation APIs, and by Safari within web pages. Technical details of the format can be found in the Interoperability Profile specification. (8045917)
Core Haptics - Known Issues
By default, haptics are disabled when microphone recording begins. You can override this by setting the AVAudioSession property allowHapticsAndSystemSoundsDuringRecording to true before activating its audio session. (25811898)
Events — such as audioContinuous, hapticContinuous, and audioCustom — can't be resumed during the event; no output occurs for that event, only for subsequent events. This applies to playback at a specific time offset, seeking, and resuming. (29274583)
CHHapticDynamicParameter instances with nonzero relative times that are sent as part of a sendParameters(_:atTime:) call on a CHHapticAdvancedPatternPlayer with the atTime parameter set to 0.0 are incorrectly applied at the beginning of the CHHapticPattern, instead of the expected nonzero relative time. This doesn't occur on a CHHapticPatternPlayer. (46316890)
Both vibrations generated through AudioServicesPlaySystemSound(_:) and vibration patterns generated through the user-created tap-to-vibrate UI are attenuated when compared to prior versions of iOS. (47448156)
Parameter Curves are not supported with a CHHapticAdvancedPatternPlayer, only a CHHapticPatternPlayer. No error is generated when a CHHapticPattern containing a Parameter Curve is passed to a CHHapticAdvancedPatternPlayer. (47891515)
Brief audio distortion occurs when starting a Playback category app such as Music in the background. For example, brief distortion occurs if you start the app from Control Center while Core Haptics audio playback using a playAndRecord audio session is already underway. (48121467)
Following any decompression to uncompressed floating-point samples, the total limit on all audioCustom resources per process is eight megabytes. (48659023)
Multiple overlapping Parameter Curves for the same CHHapticDynamicParameter.ID might result in playback artifacts. (50026384)
The maximum duration for a hapticContinuous haptic event is 30 seconds. Events exceeding this limit can be constructed and accepted by CHHapticPatternPlayer, but haptic playback will fade out after 30 seconds. (51322525)
Core Image - New Features
The init(imageURL:options:) and init(imageData:options:) initializers no longer support RAW version 5 and earlier. Version 6 and later remain supported. (50911303)
Added new APIs for instantiating and modifying the built-in Core Image filters.
The CICoreMLModel filter is enhanced to support models with an input or output of type MLFeatureType.multiArray.
Metal CIKernel instances support arguments with arbitrarily structured data.
Metal CIKernel instances support returning a group of 2 × 2 pixels.
The integer values of CIFormat symbols, such as ARGB8, have changed to a new set of values that are consistent across platforms. The former values remain supported for backward compatibility; however, you should avoid dependancies on specific numerical values.
Device Management - Resolved Issues
Users can accept invitations to App and Book Assignments. (50832260)
Find My - Known Issues
When performing an action in Find My that generates an email, you might see references to the Find My Friends and Find My iPhone apps. (51123613)
The "Notify when found" feature is currently unavailable.
Apple Pay cards might remain suspended after a device exits Lost Mode.
While iOS & iPadOS 13 remains in beta, offline-finding capability is limited.
HomeKit - Known Issues
After viewing IP camera streams in the Home app, your device won't sleep until you exit the app. (52981554)
Home Screen - Resolved Issues
Dragging app icons from Spotlight behaves as expected. (49004339)
iCloud - Known Issues
The iCloud Drive section in Settings > General > iPhone Storage might inaccurately represent the current state of files on your device. (50362095)
When creating a new Pages, Numbers, or Keynote document in a shared folder, you might see the message: "Couldn't connect to iCloud." (50827963) | Workaround: Close and reopen the document.
iCloud Resolved Issues
When manually initiating iCloud backup from Settings > iCloud Account > iCloud > iCloud Backup > Back Up Now, the progress bar completes as expected. (51030266)
Localization - Known Issues
Devices set to use certain languages might exhibit clipped or misaligned layout. (51068688)
Devices set to use certain languages might display unlocalized text. (47765173, 51197936, 51270878)
Mail - New Features
Ignore Blocked Senders can now be enabled in Settings > Mail. The blocked contacts list is shared with Messages, FaceTime, and Phone. (50775961)
Mail - Resolved Issues
You can share images directly from emails. (50538771)
Messages - Known Issues
If you're using Messages in iCloud, you might see prompts to repair your account and your messages might not sync with other devices. (53406906)
Networking - New Features
All URLSessionTask instances with a GET HTTP method that contain a body now produce the error NSURLErrorDataLengthExceedsMaximum. (46025234)
Networking - Known Issues
Starting with iOS 13 beta 4, the copy attribute of the httpBody property of NSMutableURLRequest is enforced. If the body data is mutated after the property setter has been called, data sent in the HTTP request won't include that mutation. Invoking the property getter no longer returns a NSMutableData reference, even when the setter was invoked with data of that type. As of iOS 13 beta 5, apps built using the iOS 12 SDK or previous SDKs use the legacy behavior. (53427882)
Networking - Deprecations
Removed support for FTP and File URL schemes for Proxy Automatic Configuration (PAC). HTTP and HTTPS are the only supported URL schemes for PAC. This affects all PAC configurations including, but not limited to, configurations set using Settings, System Preferences, Profiles, and URLSession APIs such as connectionProxyDictionary and CFNetworkExecuteProxyAutoConfigurationURL(_:_:_:_:). (28578280)
The URLSession and NSURLConnection APIs no longer support SPDY. Servers should use HTTP 2 or HTTP 1.1. (43391641)
Notes - Known Issues
Using search in Notes might produce unexpected results. (48238242)
Phone and FaceTime - Resolved Issues
When upgrading to iOS 13 beta, you can enter your SIM PIN during the setup process as expected. (51593059)
Screen Time - Known Issues
If you enable Share Across Devices, Screen Time settings don't sync with iCloud until your iOS device is restarted. Any edits you make to your Screen Time settings on that device before restarting are lost. (50194586)
Screen Time - Resolved Issues
Users can no longer select "One more minute" multiple times per day once they reach the limit for an app. (48773803)
Settings - Known Issues
Do Not Disturb settings might not synchronize between your phone and watch until both are updated to iOS 13 beta 4 and watchOS 6 beta 4. (52830669)
You might be unable to purchase cellular data plans on iPad. (51735832, 51737229)
Sign In with Apple - Known Issues
Real User status is currently unavailable. Sign In with Apple provides a status for new accounts but the status might return unexpected results. (51765525)
Siri - Known Issues
Shortcuts automations are temporarily unavailable. (53182885)
AirPods might disconnect unexpectedly when Announce Messages with Siri is enabled unless music is playing while receiving a new message. (50322025)
When you edit an app's intent definition file and install the app, changes aren't immediately reflected in Shortcuts. (46645833) | Workaround: Quit and relaunch Shortcuts after installing a new version of the app, or build and run the intents extension in Xcode, targeting the Shortcuts app.
The supportsOnDeviceRecognition property always returns false the first time it's accessed. After a few seconds, accessing it again returns the correct value. (47822242)
Shortcuts opened on iOS & iPadOS 13 beta are automatically upgraded and can no longer be opened on iOS 12. If a device with iOS 12 and a device with iOS 13 share an iCloud account, shortcuts might become unusable on the device running iOS 12. (50873839) | Workaround: Disable iCloud Sync between devices running iOS & iPadOS 13 beta and devices running iOS 12.
While using non-English languages, asking Siri to perform actions related to Reminders or Messages might cause the corresponding application to quit unexpectedly. (50952938)
Currently, the only supported response for INSearchForMediaIntent is INSearchForMediaIntentResponseCode.continueInApp. (51010311)
When Announce Messages with Siri is enabled, music playback might be interrupted when a message is read. (51243455)
SwiftUI - New Features
You can now create a Color from a UIColor or NSColor. (49833933)
NSManagedObject now conforms to ObservableObject. The new @FetchRequest property wrapper can drive views from the results of a fetch request, and managedObjectContext is now included in the environment. (50280673)
Gesture modifiers are renamed for consistency. For example, tapAction(count:_:) is renamed onTapGesture(count:perform:), and longPressAction(minimumDuration:maximumDistance:_:pressing:) is renamed onLongPressGesture(minimumDuration:maximumDistance:pressing:perform:). (50395282)
Text now has a default line limit of nil so that it wraps by default. (51147116)
ContentSizeCategory and several other enumerations are now CaseIterable. (51168712)
SegmentedControl is now a style of Picker. (51769046)
BindableObject is replaced by the ObservableObject protocol from the Combine framework. (50800624)
You can manually conform to ObservableObject by defining an objectWillChange publisher that emits before the object changes. However, by default, ObservableObject automatically synthesizes objectWillChange and emits before any @Published properties change.
// RoomStore.swift

import Foundation
class RoomStore: ObservableObject {

@Published var rooms: Room =

}
struct Room: Identifiable {

var id: UUID

var name: String

var capacity: Int

var hasVideo: Bool

}
// ContentView.swift

import SwiftUI
struct ContentView: View {

@ObservedObject var store: RoomStore
var body: some View {

NavigationView {

List(store.rooms) { room in

RoomCell(room: room)

}

.navigationBarTitle("Rooms")

}

}

}
@ObjectBinding is replaced by @ObservedObject.
The Identifiable protocol is now part of the Swift standard library. As a result, your model files no longer need to import the SwiftUI framework. (SE-0261)
The EnvironmentValues structure has four new properties for reading accessibility values from the environment: accessibilityDifferentiateWithoutColor, accessibilityReduceTransparency, accessibilityReduceMotion, and accessibilityInvertColors. (51712481)
The color(_:) modifier for Text is renamed foregroundColor(_:) for consistency with the more general foregroundColor(_:) view modifier. (50391847)
The BindableObject protocol's requirement is now willChange instead of didChange, and should now be sent before the object changes rather than after it changes. This change allows for improved coalescing of change notifications. (51580731)
The RangeReplaceableCollection protocol is extended to include a remove(atOffsets:) method and the MutableCollection protocol is extended to include a move(fromOffsets:toOffset:) method. Each new method takes IndexSet instances that you use with the onMove(perform:) and onDelete(perform:) modifiers on ForEach views. (51991601)
Added improved presentation modifiers: sheet(isPresented:onDismiss:content:), actionSheet(isPresented:content:), and alert(isPresented:content:) — along with isPresented in the environment — replace the existing presentation(_:), Sheet, Modal, and PresentationLink types. (52075730)
Updated the APIs for creating animations. The basic animations are now named after the curve type — such as linear and easeInOut. The interpolation-based spring(mass:stiffness:damping:initialVelocity:) animation is now interpolatingSpring(mass:stiffness:damping:initialVelocity:), and fluidSpring(stiffness:dampingFraction:blendDuration:timestep:idleThreshold:) is now spring(response:dampingFraction:blendDuration:) or interactiveSpring(response:dampingFraction:blendDuration:), depending on whether or not the animation is driven interactively. (50280375)
Added an initializer for creating a Font from a CTFont. (51849885)
You can style a NavigationView using two new style properties: StackNavigationViewStyle and DoubleColumnNavigationViewStyle. By default, navigation views on iPhone and Apple TV visually reflect a navigation stack, while on iPad and Mac, a split-view styled navigation view displays. (51636729)
When using the DoubleColumnNavigationViewStyle style, you can provide two views when creating a navigation view — the first is the master and the second is the detail. For example:
NavigationView {

MyMasterView()

MyDetailView()

}

.navigationViewStyle(DoubleColumnNavigationViewStyle())
SwiftUI - Known Issues
Using the Path structure may cause apps to crash if you're using the SDKs included in Xcode 11 beta 5. (53523206)
Using a ForEach view with a complex expression in its closure can may result in compiler errors. | Workaround: Extract those expressions into their own View types. (53325810)
Context menus might display incorrectly or crash your app unexpectedly. (53461370)
Image instances don't use resizing information configured in asset catalogs. Configure the size of an image using the resizable(capInsets:resizingMode:) modifier instead. (49114577)
SwiftUI - Resolved Issues
When pushing a view from a NavigationLink in an element of a List, the pushed view shows Button instances with the correct text color. (52858284)
SwiftUI - Deprecations
NavigationDestinationLink and DynamicNavigationDestinationLink are deprecated; their functionality is now included in NavigationLink. (50630794)
The Length type is replaced by CGFloat. (50654095)
TabbedView is now named TabView. (51012120)
HAlignment and VAlignment are now deprecated, use the more flexible HorizontalAlignment or VerticalAlignment types instead and use TextAlignment for text. (51190531)
The SelectionManager protocol is removed, use Optional and Set instances directly for selection. (51557694)
The isPresented environment value is deprecated and replaced with the more general presentationMode value. (51641238)
The StaticMember protocol is deprecated. Use protocol-conforming types directly instead. For example, use an instance of WheelPickerStyle directly rather than the wheel static member.(52911961)
Complex overloads for the background(_:alignment:) and border(_:width:) modifiers are deprecated. Use shapes in a background(_:alignment:) or overlay(_:alignment:) to draw these instead. (53067530)
SwiftUI APIs deprecated in previous betas are now removed. (52587863)
The identified(by:) method on the Collection protocol is deprecated in favor of dedicated init(_:id:selection:rowContent:) and init(_:id:content:) initializers. (52976883, 52029393)
The retroactive conformance of Int to the Identifiable protocol is removed. Change any code that relies on this conformance to pass \.self to the id parameter of the relevant initializer. Constant ranges of Int continue to be accepted:
List(0..<5) {

Text("Rooms")

}
However, you shouldn't pass a range that changes at runtime. If you use a variable that changes at runtime to define the range, the list displays views according to the initial range and ignores any subsequent updates to the range.
Several extensions to the Binding structure are removed. (51624798)
If you have code such as the following:
struct LandmarkList: View {

var landmark: Landmark

@Binding var favorites: Set
var body: some View {

List(landmarks) { landmark in

Toggle(landmark.name, isOn: self.$favorites.contains(landmarkID))

}

}

}
Define the following subscript on the Set structure:
extension Set {

subscript(member: Element) -> Bool {

get { contains(member) }

set {

if newValue {

insert(member)

} else {

remove(member)

}

}

}

}
Then, change self.$favorites.contains(landmarkID) to self.$favoriteslandmarkID.
The Binding structure's conditional conformance to the Collection protocol is removed. (51624798)
If you have code such as the following:
struct LandmarkList: View {

@Binding var landmark: Landmark
var body: some View {

List(landmarks) { landmark in

Toggle(landmark.value.name, isOn: landmark\.isFavorite)

}

}

}
Define the following collection type:
struct IndexedCollection: RandomAccessCollection {

typealias Index = Base.Index

typealias Element = (index: Index, element: Base.Element)
let base: Base
var startIndex: Index { base.startIndex }
var endIndex: Index { base.startIndex }
func index(after i: Index) -> Index {

base.index(after: i)

}
func index(before i: Index) -> Index {

base.index(before: i)

}
func index(_ i: Index, offsetBy distance: Int) -> Index {

base.index(i, offsetBy: distance)

}
subscript(position: Index) -> Element {

(index: position, element: baseposition)

}

}
extension RandomAccessCollection {

func indexed() -> IndexedCollection {

IndexedCollection(base: self)

}

}
Then, update your code to:
struct LandmarkList: View {

@Binding var landmarks: Landmark
var body: some View {

List(landmarks.indexed(), id: \.1.id) { (index, landmark) in

Toggle(landmark.name, isOn: self.$landmarksindex.isFavorite)

}

}

}
The relativeWidth(_:), relativeHeight(_:), and relativeSize(width:height:) modifiers are deprecated. Use other modifiers like frame(minWidth:idealWidth:maxWidth:minHeight:idealHeight:maxHeight:alignment:) instead. (51494692)
Third-Party Apps - Known Issues
You might be unable to stream to a Chromecast device. (51334673)
Third-Party Apps - Resolved Issues
Audio plays correctly in Instagram stories. (50433755)
WhatsApp behaves as expected when forwarding messages to a user who isn't in the recent contacts list. (45416129)
WhatsApp users no longer receive duplicate notifications or notifications without content. (50537131)
The Wells Fargo app no longer quits unexpectedly when opened or during sign-in. (51085418)
UIKit - New Features
The UITableViewCell class no longer changes the backgroundColor or isOpaque properties of the contentView and any of its subviews when cells become highlighted or selected. If you are setting an opaque backgroundColor on any subviews of the cell inside (and including) the contentView, the appearance when the cell becomes highlighted or selected might be affected. The simplest way to resolve any issues with your subviews is to ensure their backgroundColor is set to nil or clear, and their opaque property is false. However, if needed you can override the setHighlighted(_:animated:) and setSelected(_:animated:) methods to manually change these properties on your subviews when moving to or from the highlighted and selected states. (13955336)
Since iOS 8, using UISearchController with UINavigationController has required setting the definesPresentationContext property of the top view controller to true. Failure to do so leads to subtle bugs that can be hard to detect and debug. Starting in iOS & iPadOS 13 beta, if a view controller's navigationItem has a non-nil searchController, when the view controller is shown in a navigation controller, UINavigationController automatically sets that view controller's definesPresentationContext property to true. If you are targeting earlier versions of iOS, set this property before your search controller becomes active. (31338934)
The UIRefreshControl class no longer directly modifies the contentInset of its scroll view. Instead, its adjustments to the content inset will be incorporated into the scroll view's adjustedContentInset. The only exception is when the scroll view's contentInsetAdjustmentBehavior is set to UIScrollView.ContentInsetAdjustmentBehavior.never, in which case the UIRefreshControl instance will modify the contentInset directly as it did in previous releases. (35866834)
If you implement self-sizing cells in a UITableView by overriding sizeThatFits(_:) without using Auto Layout, the height you return is interpreted as the desired height for the contentView of the cell, and UITableViewCell automatically adds any additional height needed to allow room for the cell separator. If you implement manual self-sizing this way, the cell's contentView width is guaranteed to be accurate for you to use in manual layout calculations when sizeThatFits(_:) is called on the UITableViewCell. (39742612)
Trait environments, such as views and view controllers, now have their traitCollection property populated with traits during initialization. These initial traits represent a prediction of the ultimate traits that the trait environment will receive when it gets added to the hierarchy. Because the traits that are populated during initialization are just a prediction, they might differ from the traits that are received once actually in the hierarchy. Therefore, when possible you should wait to perform work that uses the traitCollection until the view, or view controller's view, has moved into the hierarchy — meaning window returns a non-nil value — so that you don't have to throw away any work done using the predicted traits if the actual traits are different. The best time to use the traitCollection is during layout, such as inside layoutSubviews(), viewWillLayoutSubviews(), or viewDidLayoutSubviews().
The traitCollectionDidChange(_:) method is only called when the value of a trait changes. Importantly, because the trait collection is now initialized to a prediction of the ultimate traits in the destination hierarchy, when the initial predicted traits match the ultimate traits in the hierarchy, traitCollectionDidChange(_:) will not be called when the trait environment is added to the hierarchy. Because traitCollectionDidChange(_:) is intended to be an invalidation callback to notify you that one or more traits changed, audit your existing implementations of this method, as well as the UIContentContainer method willTransition(to:with:), for places where you might have been relying on it to trigger initial setup. The best place to lazily perform work that uses the traitCollection is inside one of the layoutSubviews methods discussed above, but remember that these layout methods are called any time layout occurs so be sure to avoid repeating work when you don't need to. (46818941)
You can now enable debug logging to easily see when traitCollectionDidChange(_:) or willTransition(to:with:) is called on your own classes. Turn on the logging by using the following launch argument: -UITraitCollectionChangeLoggingEnabled YES. You might want to temporarily disable the Main Thread Checker while using this launch argument and running your app from Xcode to avoid extra log messages for unrelated classes. (47858564)
The UITableViewCell class's contentView property is always laid out edge-to-edge with adjacent accessories, both on the leading and the trailing side. This streamlines the layout code so developers who want the correct default offset no longer have to align their content with the content view border or the layout margin depending on whether there is an accessory on the trailing side or not. You should now always lay out their code on the layout margins of the cell's content view to get the default system insets. These insets will be adjusted automatically based on the accessories visible in the cell to match the system's default spacing. (48214114)
You can now invoke a custom initializer from a creation block that's passed through instantiateInitialViewController(creator:) or instantiateViewController(identifier:creator:). This makes it possible for you to initialize view controllers with additional context and arguments, while taking advantage of defining them in a storyboard through Interface Builder. A custom controller initializer must call its super.init(coder:) method and pass the coder argument that it receives through the creation block. (48313869)
UIKit - Known Issues
Specifying UIWindowScene.DestructionRequestOptions in Swift is currently unavailable. (51036709)
UIKit - Resolved Issues
Prior to iOS 13, UITextField assumed that the frames of its leftView and rightView were correctly set when assigned and would never change. Starting in iOS 13, the implementation of leftViewRect(forBounds:) and rightViewRect(forBounds:) now ask the view for its systemLayoutSizeFitting(_:). To achieve the previous behavior when linking against and running on iOS 13, add explicit sizing constraints on the view, wrap it in a plain UIView, or subclass the view and implement systemLayoutSizeFitting(_:). (51787798)
Voice Control - Resolved Issues
After you enable Voice Control for the first time, resources begin downloading and a progress indicator displays. (50788121)
Watch - Known Issues
Complications might disappear from Apple Watch after updating to iOS 13 beta if your watch isn't running watchOS 6 beta. (50507942)
Xcode - New Features
CAMetalLayer is now available in Simulator. (45101325)
Xcode - Known Issues
Donated shortcuts might not appear in Search while using the simulator. (50832782) | Workaround: Test on a device with Settings > Developer > Display Recent Shortcuts enabled.
Changing the volume level in Simulator while a video is playing in Safari mutes the audio. (51207286)

To update your iPhone to iOS 13 dev beta 5, you will need to be a registered developer. You can use the restore image for your iPhone available in the Developer portal (install with iTunes or Finder) or install the configuration profile then update over the air. If you already have the profile installed on your iPhone, head over to Settings –> General –> Software Update to start installing the latest beta build, or you can wait until it installs automatically if "Automatic Updates" is enabled.
