Use SDMMobileDevice.framework instead of Apple's private framework MobileDevice.framework. So it can be Sandboxed App for AppStore ^_^
Currently just clean crash log. (Apple has imposed more restrictions, we can not access installed app dir now.) As a guy with obsessive-compulsive disorder, I still feel lucky to be able to clean my iPhones' crash log --!
Where is the crash log?
Settings -> Privacy -> Diagnostics & Usage -> Diagnostics & Usage Data
Do you have or care about the same problem ?
With MyMobileCleaner, now it is not a problem.
The world is clear now ^_^
