Unable to Capture View Hierarchy on physical device

What I already did:

  • Mac / target restarted
  • Devices unpaired
  • Library/Developer removed
  • Xcode 12D4e (Appstore) reinstalled - latest for Catalina

How to reproduce the error:

  1. Empty iOS project (Hello World)
  2. Select a physical device (it works fine in the simulator)
  3. Product --> Run
  4. Debug --> View Debugging --> Capture View Hierarchy

Result:

Error:    Unable to Capture View Hierarchy.

Details:  Log Title: Data source expression execution failure.

Log Details: error evaluating expression “(id)[[(Class)objc_getClass("DBGTargetHub") sharedHub] performRequestWithRequestInBase64:@"…"]”: error: Expression can't be run, because there is no JIT compiled function

Log Method: -[DBGDataSourceConnectionLibViewDebugger _executeLLDBExpression:forRequest:onPotentialThread:iteration:]_block_invoke

Method:   -[DBGViewDebugger _initiateInitialRequestWithDataSourceVersion:]_block_invoke

Environment: Xcode 12.4 (12D4e) debugging iPhone X (Model A1865, A1901, A1902, A1903) iOS 14.7.1 (18G82).

May be your iPhone system version higher than Xcode supported. Try another iPhone which lower version.
