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 solved it by

1. remove derived data,
2. quit Xcode,
3. kill app on device,
4. start Xcode again.

However this problem continues to happen for me, 0-4 times per week. A permanent solution to this problem would be nice.
