I have a macOS app that has a minimal deployment target of macOS 10.15, recently I adapted some features with Swift Concurrency.
I built my app with Xcode 13.2 then upload to App Store Connect, but it failed.
App Store Connect reported "This bundle is invalid.", which "libswift_Concurrency.dylib" is unsupported content.
The same issue here. However, I can get my app notarized. So just no App Store.
We got same issue. As a workaround we successfully submitted our App to AppStore with Xcode 13.1
This is really not acceptable. If Apple wants to encourage developers to use the Mac App Store instead of side-loading, fix this.
