Apple's iOS 14.2 Developer Beta 3 Available for iPhone with New Core Media Features & SwiftUI Fixes

Apple released iOS 14.2 developer beta 3 for iPhone on Tuesday, Oct. 13. The update adds new glyphs for HomePod mini and Beats Flex, support for HomePod's upcoming "Intercom" feature, new Core Media features for developers, as well as resolved SwiftUI issues.

The beta 3 update, which was pushed out just before 11:30 a.m. PDT, comes two weeks days after the release of 14.2 dev beta 2 and 13 days after 14.2 public beta 2. If you're a public beta tester, you'll need to wait until Apple releases 14.2 public beta 3, which we expect to see between 10 a.m. and 1 p.m. PDT on Wednesday.

How to Install the Most Recent Beta on Your iPhone

To update your iPhone to iOS 14.2 dev beta 3, you'll 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.
