[iOS] MAUI app crashing when calling function from external library in Release mode, but works in Debug mode

MAUI .NET 9, 9.0.21, targeting iOS and Android

I'm observing the app crashing on iOS when running in Release mode build from TestFlight on physical device, but works when running in Debug mode in simulators. The app crashes when a particular method is executed from an included class library Some.External.Library.dll in the app.

The same could be observed on Android where it works in Debug, but does not work in Release mode. I've found Setting the <Optimize>False</Optimize> has allowed it to work in Release mode for Android, however this still does not work in iOS in Release mode.

I have tried setting <UseInterpreter>true</UseInterpreter> but see no change.

I've also tried setting <MtouchInterpreter>-all,Some.External.Library.dll</MtouchInterpreter> no luck

I'm unable to see logs for the app crashing in iOS in Release mode, but i have captured the logs for the app crashing on Android in Release prior to setting Optimise flag set to false if that gives any clues to a fix.

Can anyone point me in the right direction to getting this to work in iOS Release mode?

Is it possible to disable code trimming or Native AOT compiling for just this Some.External.Library.dll?

Android application is running (debug is disabled in android project properties).

    Hello,

    Is it possible to disable code trimming or Native AOT compiling for just this Some.External.Library.dll?

    Yes, you could try to specify assemblies that should be excluded from the trimming process, while allowing other assemblies to be trimmed. Please see Trim a .NET MAUI app - .NET MAUI | Microsoft Learn

    <ItemGroup>
  <TrimmerRootAssembly Include="Some.External.Library" />
</ItemGroup>

    Best Regards,

    Wenyan Zhang
