What’s New in Xcode 11.2 Beta

Overview

Overview -Xcode 11.2 beta includes SDKs for iOS 13.2, macOS Catalina 10.15, watchOS 6.1, and tvOS 13.2. Xcode 11.2 beta supports on-device debugging for iOS 8 and later, tvOS 9 and later, and watchOS 2 and later. Xcode 11.2 beta requires a Mac running macOS Mojave 10.14.4 or later.

Debugging

Known Issues

• Watch apps might fail to launch on Apple Watch from Xcode with the error: ”Failed to use existing instance 0 for app with bundle identifier: com.apple.Carousel.” This can occur when the iPhone and Apple Watch are too far from the wifi network base station and have a weak signal, the wifi network is congested, or the network doesn’t support peer-to-peer connections. (51431622)Workaround: Disable wifi on the Apple Watch in Settings to force use of bluetooth, or set up a separate 2.4GHz wifi base station and disable auto-connecting to the ‘bad’ wifi network.

Interface Builder

New Features

• Added support for configuring WKInterfaceAuthorizationAppleIDButton styles. (53251536)

Resolved Issues

• Fixed an issue with UITabBarController where decoding an instance from a storyboard would create extra views at the left end of the screen. If you worked around this issue on Xcode 11.0 or 11.1 by creating a subclass of UITabBarController and hiding extra views in the initializer you can remove the workaround. (55310448)
• Fixed a crash that occurred in iOS/tvOS projects when reselecting the currently selected color in a user-defined runtime attribute. (55464140)
• The host system’s appearance no longer affects which fallback color is archived for an adaptive asset catalog color. (55570108)

Localization

Resolved Issues

• Fixed a crash when importing a localization with xcodebuild into a project referencing a Swift package. (55636751)

Simulator

New Features

• simctl video recording now produces smaller video files, supports HEIC compression, and takes advantage of hardware encoding support where available. In addition, the ability to record video on iOS 13, tvOS 13, and watchOS 6 devices has been restored. (50625716, 54409532, 55207068).NoteThe flags and arguments supported by simctl video recording have changed. See xcrun simctl help io for more information.
• Simulator now has a menu item and keyboard shortcut to bring up the app switcher in iOS simulators. (54793361)

Resolved Issues

• Fixed a crash loop that could occur on macOS 10.15 Catalina when using iCloud Drive in simulated devices running older versions of iOS. (51392951, 54282967, 54818084)
• Fixed an issue causing simulated devices running iOS 13 to display a black window instead of enabling an external display or a CarPlay display. (53966664)

Swift Compiler

New Features

• Swift function builders use a new type checking algorithm that improves compile times and eliminates many instances of ”unable to type-check this expression in reasonable time” errors for SwiftUI-heavy code. (50150793)

Resolved Issues

• The enum NEHotspotConfigurationError in the NetworkExtension framework changed back to NS_ENUM (from NS_ERROR_ENUM), as it was before Xcode 11.0. (54134493)
• Fixed a runtime crash that would occur when running watch apps statically linked with Swift libraries. (55082864)

Swift Packages

Resolved Issues

• The scheme autogenerated for a Swift package will be automatically updated when the package adds or removes targets. (50586754, 54777895)

SwiftUI

Known Issues

• Certain downloadable project files from the SwiftUI tutorials inside Xcode’s documentation viewer might fail during the download process. (55575465)Workaround: Open the web link using the sharing button and download the sample files directly from the online version of the tutorial.

watchOS

Known Issues

• watchOS applications built with the watchOS 6 SDK and a deployment target of watchOS 5.3 will crash on launch. (55360395)Workaround: Set the __WKEXTENSIONMAIN_LEGACY_TARGET_5_3 build setting to “legacy,” or use another deployment target instead of 5.3.
