Unable to bind native iOS framework that uses Async/Await in iOS 14

[jslew]

Having exactly the same problem as #13605, except now trying to back-deploy to iOS 14 (not 13, which was originaly reported). Adding a reference to Xamarin.iOS.SwiftRuntimeSupport does not fix this with the current toollchain. Perhaps the package needs to be updated again?
@chamons or @rolfbjarne, any idea?

Thanks.

Expected Behavior

Xamarin.iOS app which references a native framework that (internally) uses swift concurrency should run without issue.

Actual Behavior

App crashes as soon as native code using swift concurrency is run.

Example Project (If Possible)

will add a minimal repro project shortly.

I think it may be because of this line from Xamarin.iOS.SwiftRuntimeSupports.targets:
<_SRSMasterAfterTargets>_CodesignNativeLibraries</_SRSMasterAfterTargets>
_CodesignNativeLibraries does not seem to exist anymore, so the targets in this package which copy things are not actually running.

[jslew]

Yep, that seems to be the problem. Changed to:
<_SRSMasterAfterTargets>AfterCodesign</_SRSMasterAfterTargets>
and all seems well again.
