When I use an iOS 14.5 mobile phone to run the program, it will crash on the breakpoint. If I change to an iOS 14.2 mobile phone, the breakpoint debugging can be performed normally.


crash log:
Details

Lost connection to the debugger on “iPhone”.
Domain: IDEDebugSessionErrorDomain
Code: 4
Recovery Suggestion: Restore the connection to “iPhone” and run “***” again, or if “***” is still running, you can attach to it by selecting Debug > Attach to Process > ***.

Accepted Answer
Running/debugging apps on iOS 14.5+ devices is not supported with Xcode 12.4.

You should better prepare an upgraded Mac and try with Xcode 12.5.
