Using VS22 Xamarin

🐛 Bug Report

When I add the NuGet package and the try to run on the iPhone I get the error below.

The "UnpackFrameworks" task failed unexpectedly.
System.IO.IOException: The file 'obj\iPhone\Debug\device-builds\iphone7.2-12.5.5/Frameworks\FirebaseMessaging.framework\FirebaseMessaging' already exists.

Platform:

• 📱 iOS

Same here... Do you found a workaround?

Found a discussion about it:

#428

[AlleSchonWeg]

Do you try to delete obj and bin folders via file manager?

No, not yet, started coding in swift!

[wickshot]

Do you try to delete obj and bin folders via file manager?

Yes, tried this, same result

Yes, tried this, same result

Try disable hot restart and/or hot reload.
Do you have manually installed some Xamarin.Firebase.* nugets?

The path in your error message looks crazy. Mixed with slashe and backslashes.

[wickshot]

No, no other firebase nuggets installed. I've even tried installing on a new clean project, same result when I try to run on iOS

[Luisalvarenga]

I guess its a dependency problem by xamarin/GoogleApisForiOSComponents#564 in which this package needs to be updated asap.

[AlleSchonWeg]

I updated the following nugets (ios Project) via Transitive packages to version 8.10:

<PackageReference Include="Xamarin.Firebase.iOS.CloudMessaging">
  <Version>8.10.0</Version>
</PackageReference>
<PackageReference Include="Xamarin.Firebase.iOS.Installations">
  <Version>8.10.0</Version>
</PackageReference>

Every time i need to delete obj folder via explorer to compile successfully.

Another workaround is to edit Xamarin.iOS.HotRestart.targets file:

C:\Program Files\Microsoft Visual Studio\2022\Enterprise\MSBuild\Xamarin\iOS\Xamarin.iOS.HotRestart.targets
Path depends on your VS version.

Search UnpackFrameworks node and add ContinueOnError="true". Like this:

		<UnpackFrameworks ContinueOnError="true"
			ReferencedAssemblies="@(AssembliesWithFrameworks)"
			IntermediateOutputPath="$(DeviceSpecificIntermediateOutputPath)">

			<Output TaskParameter="Frameworks" ItemName="_UnpackedFramework" />
		</UnpackFrameworks>

I don't have an UnpackFrameworks node in my Xamarin.iOS.HotRestart.targets. Where in the file should this setting live?

[JayWilk]

ffs, i have nothing but problems trying to develop a very simple app using Xamarin / MAUI, think I'll switch to react native this has been the last straw tbh
