I develop app in xcode 6. And then device connected i run app with debug. After i can disconnect device from xcode and again run app. And it's runs.
But today begins some problems i run app with run button in xcode 7 -> app run normally, and work good.
After i disconnect device from my mac, and try run app by press app icon on device and got crash
