2025-01-06T07:06:59.42+00:00 What's the debug target?
I selecte the project to run in MAC and from menu run the app with/without debugging
and I got this image error above.
Do you run the app on an iOS simulator? If so, what's the Xcode version?
Can you explain how to check both questions?
I'm using VS CODE.

Wenyan Zhang (Shanghai Wicresoft Co,.Ltd.) 34,951 Reputation points Microsoft Vendor
2025-01-06T09:34:50.9866667+00:00 The debug target is from the language status item at the bottom right of VS Code (you can find it clicking the '{}' icon)
I understand you are using VS Code on Mac. If you target on iOS and test on an iOS simulator, we can investigate if the issue is related to Xcode version.

Bruce (SqlWork.com) 69,976 Reputation points2025-01-06T18:43:06.0766667+00:00 the error is pretty clear. when compiling to release (AOT) one of your dependent library is not supported. You might try:
<UseInterpreter>true</UseInterpreter>
in the release build.

2025-01-07T09:30:14.92+00:00 The status bar work as expected.
But i added this to csproj file to enable the interpreter.
try these two options and got same error.
Please help.
The Mono interpreter can be enabled in iOS release builds by setting the
$(UseInterpreter)MSBuild property totruein your .NET MAUI app's project file:XMLCopy
<PropertyGroup Condition="$(TargetFramework.Contains('-ios')) and '$(Configuration)' == 'Release'">The interpreter can also be enabled for Mac Catalyst release builds on ARM64:
XMLCopy
<PropertyGroup Condition="'$(RuntimeIdentifier)' == 'maccatalyst-arm64' and '$(Configuration)' == 'Release'"> -

2025-01-07T17:08:51.07+00:00 you should check with the library owner. see issue:
https://github.com/mono/SkiaSharp/issues/1885
as the bug has been open for 3 years, you will probably need to fork and fix yourself.

2025-01-08T09:27:02.4666667+00:00 OK. It would be easier to diagnose the problem if you shared the text.
As Bruce, the log shows that the issue is from SkiaSharp. When you run an empty template MAUI app, does the issue still exist?

2025-01-15T16:56:40.9233333+00:00 the default project template includes windows, iOS and android targets. this means you either install all the build tools for each platform or edit the project file to limit the targets to only what you want.
also as Maui 8 support ends in May, you should probably install net 9 and Maui 9 to start you project. The newer tools may also have fewer issues.
