Build System

Known Issues

• Swift Playgrounds app projects with package dependencies fail to build for Mac Catalyst when a package specifies .iOS(...) in its platformsarray in the manifest, but doesn’t specify .macCatalyst(...). (88726762)Workaround: Add .macCatalyst(...) to the platforms array with the same value as the iOS(...) entry.

Devices

Known Issues

Swift

Resolved Issues

• The async version of addTeardownBlock method in XCTestCase is now available. (90665371)
• Closures that are guaranteed to run on the main actor are now permitted to reference local variables from their enclosing scopes that are also running on the main actor.

@MainActorclass MyController: UIViewController { var isExcited: Bool = false func doSomething() { var title = “Hello” Task { @MainActor in if isExcited { // okay, accessing main actor-isolated stored property title += “!” // okay, accessing main actor-isolated local variable } } }}

Swift Packages

Resolved Issues

• Fixed a bug that prevented Swift Packages from finding a package plug-in tool if a target in a different package than the plug-in that requires it built the tool. (90650826)

Testing

Known Issues

• Xcode crashes if you attempt to run unit or UI tests for watchOS apps when the Run scheme action’s executable is set to None. (74928871)Workaround: Set the Run scheme action’s executable to a valid WatchKit app target built by the scheme.
