Build from Visual Studio 2022 17.8.0 Preview 3.0 paired to Mac failing if using a Nuget package with xcframework reference #19173

Closed skha83 closed 11 months ago

skha83 commented 11 months ago

Might be something similar to #19152 or at least the second comment in that issue.

Steps to Reproduce

  1. Create new Blank Maui App from Template
  2. Add Nuget Package References to a package containig a xcframework in this case Cognex.cmbSDK.Maui which is a barcode scanner
  3. Connect to Mac
  4. Deploy to real device or simulator

Expected Behavior

App builds and deploys to device without problems

Actual Behavior

The build fails. This Nuget package and build worked on previous preview versions and RC1 of .NET 8.0. I have tried with both Xcode 14.3 and Xcode 15 on the remote Mac.

The build fails with the following warning and errors. The first warning is probably what generate the last error as it can't find symbol references because of the warning. I have checked that the file is located in the given folder. Warning in the start of the build:

OK, I can reproduce, and I'll try to fix this next week.

philipag commented 11 months ago

@rolfbjarne I see you fixed this. Is it possible to install this updated build task on top of the latest VS 17.8.0 Preview 3 so that I can continue development?

rolfbjarne commented 11 months ago

@philipag I haven't tested this, but there may be a workaround you can apply locally:

  1. Locate the file Xamarin.Shared.targets - it's probably something like C:\Program Files\dotnet\packs\Microsoft.iOS.Sdk\16.4.8968-net8-rc2\tools\msbuild\iOS\Xamarin.Shared.targets - and open it in a text editor.
  2. Find the _ExpandNativeReferences target (around line 140):
<Target Name="_ExpandNativeReferences" Condition="'$(DesignTimeBuild)' != 'true'" DependsOnTargets="_DetectSdkLocations;_ComputeTargetArchitectures;_GenerateBundleName">
    <ItemGroup>
        <_XCFrameworkNativeReference Include="@(NativeReference -> '%(Identity)/.')" Condition="'%(Extension)' == '.xcframework'" />
        <_FrameworkNativeReference Include="@(NativeReference -> '%(Identity)/%(Filename)')" Condition="'%(Extension)' == '.framework'" />
        <_FileNativeReference Include="@(NativeReference)" Condition="'%(Extension)' != '.framework' And '%(Extension)' != '.xcframework'" />
    </ItemGroup>
    <ResolveNativeReferences
        SessionId="$(BuildSessionId)"
        Condition="'$(IsMacEnabled)' == 'true' And '$(IsBindingProject)' != 'true'"
        Architectures="$(TargetArchitectures)"
        FrameworksDirectory="$(_AppFrameworksRelativePath)"
        IntermediateOutputPath="$(DeviceSpecificIntermediateOutputPath)"
        NativeReferences="@(_XCFrameworkNativeReference);@(_FrameworkNativeReference)"
        References="@(ReferencePath)"
        SdkIsSimulator="$(_SdkIsSimulator)"
        TargetFrameworkMoniker="$(_ComputedTargetFrameworkMoniker)"
        >
        <Output TaskParameter="NativeFrameworks" ItemName="_ResolvedNativeReference" />
    </ResolveNativeReferences>

    <ItemGroup>
        <_FrameworkNativeReference Include="@(_ResolvedNativeReference)" Condition="'%(Kind)' == 'Framework'" />
        <_FileNativeReference Include="@(_ResolvedNativeReference)" Condition="'%(Kind)' == 'Static' Or '%(Kind)' == 'Dynamic'" />
    </ItemGroup>
</Target>
  1. Remove the SessionId="$(BuildSessionId)" line, so that it reads:
<Target Name="_ExpandNativeReferences" Condition="'$(DesignTimeBuild)' != 'true'" DependsOnTargets="_DetectSdkLocations;_ComputeTargetArchitectures;_GenerateBundleName">
    <ItemGroup>
        <_XCFrameworkNativeReference Include="@(NativeReference -> '%(Identity)/.')" Condition="'%(Extension)' == '.xcframework'" />
        <_FrameworkNativeReference Include="@(NativeReference -> '%(Identity)/%(Filename)')" Condition="'%(Extension)' == '.framework'" />
        <_FileNativeReference Include="@(NativeReference)" Condition="'%(Extension)' != '.framework' And '%(Extension)' != '.xcframework'" />
    </ItemGroup>
    <ResolveNativeReferences
        Condition="'$(IsMacEnabled)' == 'true' And '$(IsBindingProject)' != 'true'"
        Architectures="$(TargetArchitectures)"
        FrameworksDirectory="$(_AppFrameworksRelativePath)"
        IntermediateOutputPath="$(DeviceSpecificIntermediateOutputPath)"
        NativeReferences="@(_XCFrameworkNativeReference);@(_FrameworkNativeReference)"
        References="@(ReferencePath)"
        SdkIsSimulator="$(_SdkIsSimulator)"
        TargetFrameworkMoniker="$(_ComputedTargetFrameworkMoniker)"
        >
        <Output TaskParameter="NativeFrameworks" ItemName="_ResolvedNativeReference" />
    </ResolveNativeReferences>

    <ItemGroup>
        <_FrameworkNativeReference Include="@(_ResolvedNativeReference)" Condition="'%(Kind)' == 'Framework'" />
        <_FileNativeReference Include="@(_ResolvedNativeReference)" Condition="'%(Kind)' == 'Static' Or '%(Kind)' == 'Dynamic'" />
    </ItemGroup>
</Target>
  1. Try to build again.

With this temporary fix I'm able to build my app targeting iOS again πŸ‘ thx a lot

OudomMunint commented 10 months ago

Got this error when trying the temp fix unfortunately: Error MSB4018 The "ResolveNativeReferences" task failed unexpectedly.

psdiviso commented 10 months ago

@rolfbjarne Hello. When I try your fix it seems like it works but when I try to open the app on the phone after build is done it just opens quickly and then closes again.

montrelln commented 10 months ago

@rolfbjarne this happens because MobileAds.SharedInstance is null with in the AppDelegate.cs FinishedLaunching method. This work around only allows you to build locally, but when you connect to mac you receive a totally different error. Have anyone found a fix where you can actually build using remote device, while paired to a mac?

This should be fixed once we release .NET 8.
