The Xcode real machine in iOS 7 can run after debugging. . . If you don’t run to the startup page directly without xcode, you will be in Flashback.
In Flashback, you can look at the log, and use your mobile phone to connect Xcode to check the log of your mobile phone.
You can also use leaks tests to see where the specific code jumps.
Ps: It is possible to use some functions to run on a real machine. like: Turn on the camera. . .
