Apps built with Xamarin.iOS crash for the title reason.
The app consists of.
Xamarin.Forms + iOS Native Library.
It uses the "async await" instruction in the iOS Native Library, which requires libswift_Concurrency.dylib to execute, but the app built with Xamarin does not contain it.

dylibsas NativeRefereces in the Xamarin project? -

2023-02-19T02:20:35.3233333+00:00 - iOS Native Library
- iOS Proxy Library
- Xamarin.iOS Binding
- Xamarin.iOS App
iOS Native Library use async functions, they need libswift_Concurreny.dylib.
If I build a Native App with #1 library. Xcode will insert libswift_Concurreny.dylib to the App without any settings. However Xamarin.iOS build didn't insert that library file.
Acutually libswift_Concurreny.dylib exists in the system directory since iOS 15.
like) /usr/lib/swift/libswift_Concurrency.dylib.
But iOS 13 and 14 does not have that, that's why Xcode insert automatically it.
like) SmapleApp.app/Frameworks/libswift_Concurreny.dylib

2023-02-20T06:12:42.3833333+00:00 Please try to use the SwiftRuntimeSupport NuGet package to automatically include required dylib dependencies into the resulting application package. Please refer to the Consume the Xamarin binding library part in the doc - Bind iOS Swift libraries - Xamarin | Microsoft Learn
