OS: macOS 11b3
Xcode version 12 beta 3 (12A8169g)
Seems to be tied to AVKit the VideoPlayer SwiftUI view.
Detailed error messages:
/Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.0.sdk/System/Library/Frameworks/_AVKit_SwiftUI.framework/Modules/_AVKit_SwiftUI.swiftmodule/x86_64-apple-macos.swiftinterface:4:8: Failed to build module 'AVFoundation' from its module interface; the compiler that produced it, 'Apple Swift version 5.3 (swiftlang-1200.2.22.2 clang-1200.0.25.1)', may have used features that aren't supported by this compiler, 'Apple Swift version 5.3 (swiftlang-1200.0.22.4 clang-1200.0.25.1)'
The above seems like it is a minor Swift compiler mismatch, but interested to see if others have seen this. If this is an Swift bug I will file Feedback.
