I'm having a very annoying issue right now regarding iOS. I can't debug on a physical device because the application is being killed by iOS Watchdog. I don't understand why since it's working fine on the simulator.

Here is the debug output.

The app has been terminated.

Here is my configuration for debug.

</When>

This is why I think it`s the iOS Watchdog.

I think it's also worth it to add but I just tested a standard MAUI .NET 6 application and it's working fine on my iPhone.

Aside from what's mentioned here, I do not know: https://github.com/dotnet/maui/issues/11392#issuecomment-1339584185.

Hot Release is already completely disable in Visual Studio for me. Well let me know if you find anything, it makes debugging impossible for iOS on a real device.

Thanks for the update. We'll comment on the other issue to mention we're blocked. Let's track in Uno with #10748

jeanplevesque Dec 16, 2022

Could we work around the issue by disabling some debugger features? The problem only happens in debug. Is it faster if you enable Just My Code?

Just check. Just My Code is already enable in Visual Studio.
