Hi everyone,

I'm running into an issue with XCode 12 where I can't debut any mac apps. It builds successfully but after a few seconds it seems like the debugger crashes in a method called 'addSwizzler'. The app does not even get to the AppDelegate.

If I then run the app directly from the Products folder then the app runs correctly but I cannot debug it.

Is anyone experienced something similar?

Thanks!!

Is this running Xcode 12 beta on 10.15.x? Or on 11.0 beta?

If you create a new project from the macOS > App template, can you debug that?

I just tried with a totally empty project macOS > App template and the same thing happens: it builds successfully but after a few seconds it seems like the debugger crashes in a method called 'addSwizzler'.

I'm on XCode 12 beta on Big Sur beta 4.

Is it the debugger crashing? Or the app being debugged?

My mac app was crashed with Xcode 12.2 beta on 11.0 beta, at dylddebuggernotification Thread1. But it runs ok at Xcode 11.3 on 10.15.
I build an empty project with macOS app-> objective-c(storyboard), cashed the same.
