Using VS 17.14.0 Preview 1.1 and XCode 16.2 I can not compile a Maui application to a remote iPhone device

Question

Using Visual Studio version 17.12 Preview 1 and XCode 16.0 Beta I was able to connect to a remote iPhone and deploy my Maui app to the physical device. I however can not debug the app. So my development environment/MAC is set up properly.

Updating Visual Studio to 17.14.0 Preview 1.1 and using XCode 16.0 Beta or XCode 16.2 and trying to connect to a Remote Device I get the following error:

This debug engine does not support exception conditions. The condition(s) will be ignored.

Object reference not set to an instance of an object.

Normally I get the screen to connect to the MAC engine but I don't even get this screen anymore. There is clearly a problem with the latest version of Visual Studio.

Ever since XCode 16 was released I have not been able to reliably connect to the MAC and deploy and debug my Maui app.

Hello,

Preview version is not supported on Q&A. About the preview VS issue, you could report the problem with VS - Report a problem with Visual Studio - Visual Studio (Windows) | Microsoft Learn

Xcode16.2 support has been included in the latest VS release version (17.13.2).

Also, you could clean the caches and re-pair to mac after using the latest VS release version.

Please try removing the ~/Library/Caches/Xamarin/XMA/SDKs/dotnet/ folder on the Mac and removing the %localappdata%\Temp\Xamarin\XMA folder on your Windows machine.

Best Regards,

Wenyan Zhang
