Device logs not appearing in Xcode

Better Method to take device logs:

~/Library/Logs/CrashReporter/MobileDevice/<your iPhone’s name>/

The device logs are now contained in SQLite databases in this folder:

~/Library/Developer/Xcode/iOS Device Logs

Clear that out and take control of your CPU from Xcode again! Once its cleared out then maybe you'll get it to show the one you want if to perform the crash again.
