failed to send the qLaunchSuccess packet, can't debug in the device

Question

When I run the application, it is installed in the device, but will crash immediately. I want to debug in the device, below is the information:

error

Answer 1

I see this error all the time IF I was stopped due to a breakpoint and I just hit the run button (not the debugger's resume button). If I remember to hit stop before rerunning, I don't get the error. I can't turn off entitlement as the app I'm developing is one that will be using iCloud. Also, I can prevent the problem by resuming the app so that whatever Run does to stop an executing program handles it cleanly.
