App crash after some time.

Hello everyone,


I´ve got a problem. I do not know whether it is normal or not.

If I install an app on my phone via the scheme menu and the play button in XCode, it will work for some, very indefinite, time. After a period of time the app crashes and I have to reinstall it. It does not work anymore. Does anyone know the solution for my problem?


I wish you a nice weekend
