Apple iOS 13 Public Beta 3 Available, Includes Updates to 3D Touch, Photos, Icons & More

Jul 18, 2019 05:00 PM

Jul 19, 2019 03:35 PM

The wait wasn't so long this time. Apple released public beta 3 for iOS 13 on Thursday, July 18, just one day after the release of developer beta 4. For context, Apple took five days to seed public beta 2 after releasing dev beta 3, so it's a pleasant surprise that the latest public beta dropped so soon.

Public beta 3, alongside its mirror update, dev beta 4, are the smallest updates to the iOS 13 beta cycle thus far. That's not to say Apple skimped on new features and changes — you'll find:

new animation when sharing a picture in Photos
counter for the number of similar pictures hidden in curated areas of Photos
functionality updates to 3D Touch
new Voice Messages icon
corrected app menus on the home screen
new Share sheet colors
new "Rearrange Apps" option in the quick actions menu on the home screen

In the grand scheme of iOS 13, these updates might be minor. However, it is possible we'll discover more features and changes as we continue to dig through iOS 13 beta 3, so stay tuned for any future news.

If you want to see all of the official changes listed by Apple, here are the release notes published for dev beta 4, which are the same for public beta 3.

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.

Users are prompted to authenticate when using the SecureEnclave API with access control set on keys. (51279188)
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)
Books - Resolved Issues
Locally downloaded cloud items don't move back to iCloud after upgrading to iOS & iPadOS 13 beta. (51306790)
A predictive text bar no longer appears unexpectedly when reading certain books. (51584308)

The garage door button consistently appears in the CarPlay Dashboard. (50275274)
The map style for navigation apps changes dynamically between dark and light modes. (50986173)
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 Haptics - Resolved Issues
When audio generated by Core Haptics is played using an audio session category or mode that normally supports Bluetooth or wired headphone output, audio plays as expected. (29939183, 50905288)
Creating a hapticContinuous event with an attackTime of 1.0 then dynamically increasing the attack time by 1.0 no longer causes erroneous behavior. (50386282)
The default value for audioBrightnessControl is now 0, not 1. (50310604)
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.
Core Media - Resolved Issues
Media services no longer quits with the message "AVFoundation error AVErrorMediaServicesWereReset -11819" when you play a low-latency HLS stream if the network link doesn't negotiate TCP ECN. (51690639)
Core ML - Resolved Issues
In the MLRecommender model, the exclude and restrict parameters are optional as expected. (50348777)
Device Management - Known Issues
Users can't accept an invitation to App and Book Assignments. (50832260)
Device Management - Resolved Issues
MDM queries no longer return unmanaged data, such as profiles and certificates installed using Apple Configurator. (50857952)
After completing User Enrollment, Reminders can be enabled for the Managed Apple ID. (48820760)
After completing User Enrollment, you're no longer prompted to reenter your Managed Apple ID credentials when viewing account details in Settings > Passwords & Accounts. (48605466)
You can now access the Enterprise iCloud Drive from managed apps when the managed "Open-in" restriction is enabled on a User Enrollment. (51016087)
On a User Enrollment, you can install enterprise apps after removing and then reenrolling in MDM. (50959631)
FaceTime - Resolved Issues
You no longer need to toggle the Attention Correction setting at least once in order to disable it. (52054477)
Files - Resolved Issues
Using Files in Schoolwork is now supported. (51588407, 51277263)
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 - Known Issues
Dragging app icons from Spotlight currently has no effect. Instead, drag app icons from the Dock. (49004339)
Home Screen - Resolved Issues
Items in Quick Action menus have correctly sized icons. (50561570)
When viewing widgets for the first time after restarting your device, the Show More toggles appear correctly. (50966601)
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.
When manually initiating iCloud backup from Settings > iCloud Account > iCloud > iCloud Backup > Back Up Now, the progress bar doesn't complete. However, this doesn't mean that the backup isn't complete. Once the text below the progress bar changes from "Backing Up" to "Updating iCloud," it indicates that the backup completed. However, the iCloud sync doesn't complete due an issue with notes syncing with iCloud. Your notes might not be up to date on iCloud compared to the notes on your device. (51030266)
iCloud - Resolved Issues
All of your iCloud Drive data is consistently present after upgrading to iOS 13 beta. (51787170, 51950018)
Documents download correctly in iCloud Drive. (52295165)
The content of folders inside an iCloud Shared Folder are available to other users viewing your shared folder. (51591135)
Pages, Numbers, and Keynote documents in shared folders correctly show an error message when you try to access them from iCloud.com. (50738067)

You can disable QuickPath typing. (50989321)
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)
Location - Resolved Issues
Apps that receive user location are no longer erroneously attributed large numbers of locations even though only a few locations were actually received. (52240105)
Requesting Always authorization and receiving Provisional Always authorization is no longer incorrectly delivered to the CLLocationManagerDelegate as CLAuthorizationStatus.authorizedWhenInUse. (51475789)
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 - Known Issues
You might be unable to share an image directly from an email. Instead, forward the email with attachments. (50538771)
Maps - Resolved Issues
Route lines display correctly when sharing a trip ETA. (50904902)
You can navigate from an origin location that's different than your current location when a watch running watchOS 6 beta is paired to your iPhone running iOS 13 beta. (47399367)
Messages - Resolved Issues
Animoji and Memoji mirror your face as expected starting in build 17A5522g. (52199654)
Music - Resolved Issues
Music doesn't quit unexpectedly when reordering songs in Up Next. (51639471)
Music no longer appears paused even though audio is playing. (49926478)
You can share or tap album and artist links. (49675331)
Networking - New Features
All URLSessionTask instances with a GET HTTP method that contain a body now produce the error NSURLErrorDataLengthExceedsMaximum. (46025234)
Networking - Resolved Issues
For a background-configuration URLSession, an HTTP Set-Cookie header sent from a server behaves as expected. (47044416)
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 - Known Issues
When upgrading to iOS 13 beta, you might be unable to enter your SIM PIN during the setup process. Instead, use Settings > Cellular > SIM PIN to unlock your SIM. (51593059)
Phone and FaceTime - Resolved Issues
The status bar accurately reflects the current connection state when transitioning in and out of cellular service. (50821677)
Podcasts - Resolved Issues
Transcript search is now available. (50425804)
Podcast artwork doesn't overlap other UI elements. (50859386)
Safari and WebKit - Resolved Issues
Keyboard shortcuts behave as expected when using non-English language settings. (50979111)
Screen Time - Known Issues
Users can select "One more minute" multiple times per day instead of only once each time they reach the limit for an app. (48773803)
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)
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
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)
Siri - Resolved Issues
Shortcuts-enabled media apps no longer appear to have SiriKit media support. (51010590)
To support Announce Messages with Siri in your messaging app, add INSearchForMessagesIntentIdentifier to your notification category. (50462393)
SwiftUI - New Features
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: stack and doubleColumn. 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 doubleColumn 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(.doubleColumn)
SwiftUI - Known Issues
When pushing a view from a NavigationLink in an element of a List, the pushed view shows Button instances with black text and NavigationLink instances with black text and a chevron. (52858284)
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
View modifier methods return opaque views (some View) rather than complex generic types. (46140669)
ScrollView instances always size themselves as expected for their content. (49204262)
The tabItemLabel(_:) modifier — now named tabItem(_:) — now accepts @ViewBuilder closures. (51502668)
Text in previews in Xcode switch to the correct appearance in Dark Mode. (51486412)
SwiftUI - Deprecations
The identified(by:) method on the Collection protocol is deprecated in favor of dedicated init(_:id:selection:rowContent:) and init(_:id:content:) initializers. (52976883)
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)
WhatsApp might quit unexpectedly when forwarding messages to a user who isn't in the recent contacts list. (45416129)
WhatsApp users might receive duplicate notifications or notifications without content. (50537131)
Audio might not play in Instagram stories. (50433755)
The Wells Fargo app might quit unexpectedly when opened or during sign-in. (51085418)
Third-Party Apps - Resolved Issues
Didi displays map data correctly. (48386075)
Apps that were unable to backup or restore data to iCloud Drive can now do so once again. (50784901)
Gmail behaves as expected when you tap the "View entire message" link. (51451630)
Dragging and dropping an NSUserActivity-backed drag item creates a new scene.
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
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)
Specifying UIWindowScene.DestructionRequestOptions in Swift is currently unavailable. (51036709)
Voice Control - Known Issues
After you enable Voice Control for the first time, resources begin downloading in the background. Once the download completes, you will receive a notification that Voice Control is ready for use. (50788121)
Voice Memos - Resolved Issues
Voice Memos synced from iCloud play correctly. (51492047)
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)
Watch - Resolved Issues
Settings appear properly in the Apple Watch app if you've recently reinstalled a built-in app. (51689111)
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)
Xcode - Resolved Issues
Calls to SKProductsRequest no longer fail in Simulator. (50875951)
Swift interfaces for several new URLSession APIs are now available. (50517967)
Dark Mode is available in Simulator (50699968)
When running your app from Xcode, you no longer see console errors about UIKit classes that override the traitCollection getter. (51651561)

To update your iPhone, you need to be an iOS beta tester. Sign up through Apple's beta site, download and install the configuration profile, then update over the air. If you already have the profile, go to Settings –> General –> Software Update to begin the installation of the latest beta build, or you can wait until it installs automatically if "Automatic Updates" is enabled.
