Apple Releases iOS 14.6 Developer Beta 2 for iPhone

Apple seeded developers the second iOS 14.6 beta today, Friday, April 30. The update (build number 18F5055b) comes four days after the launch of iOS 14.5, which introduced over 60 new features and changes to iPhone, and eight days after the first 14.6 beta hit developers' iPhones.

Apple released this update just past 10 a.m. PDT, the standard release time for developer beta updates. The company waited roughly three additional hours before releasing the second 14.6 public beta. Both versions of the beta are the same, and introduce minor, under-the-hood fixes that most testers won't see.

iOS & iPadOS 14.6 Beta 2 Release Notes
Overview
The iOS & iPadOS 14.6 SDK provides support to develop apps for iPhone, iPad, and iPod touch devices running iOS & iPadOS 14.6 beta 2. The SDK comes bundled with Xcode 12.5, available from the Mac App Store. For information on the compatibility requirements for Xcode 12.5, see Xcode 12.5 Release Notes.

Xcode: Deprecations
Don't use the iOS MinimumOSVersion information property list key to declare the minimum release of macOS in which your app runs. Use LSMinimumSystemVersion instead. (73890473)

Future releases of macOS ignore the MinimumOSVersion key in Mac apps, including apps built with Mac Catalyst.

Future releases of macOS use the LSMinimumSystemVersion key in iOS apps built with Xcode 12.5 or later. If an iOS app doesn't include an LSMinimumSystemVersion key, future releases of macOS compare the app's MinimumOSVersion with the version of its Mac Catalyst runtime to determine compatibility.

How to Install the Latest iOS 14.6 Beta

You'll need an Apple developer account to update your iPhone. You can get the restore image from your dev portal, then install it with iTunes or Finder. Otherwise, install the configuration profile, then update by going to Settings –> General –> Software Update. Finally, you can simply wait for it to auto-install if you have a dev profile and "Automatic Updates" is enabled.
