Xamarin Studio - Could not connect to the debugger

Posted 2020-10-05

My Xamarin ios app will build successfully, however, during launch it will flash a black screen and immediately return to my phones home screen exiting my app without an error. 
Upon reviewing Xamarin Studio, the status appears at top:

Waiting for debugger to connect to Phone on port 10000 view USB...

and simply hangs for ~90 seconds. Afterwards the message "Could not connect to the debugger" appears within Xamarin Studio

 

编译没问题，release也能运行，就是无法debug，app一运行就闪退，在debug log中没有任何信息。换个iphone就好了。

今天发现解决方法了：

 

去掉iOS Build中Enable device-specific build就好了。??
