iOS Application exits when not in xcode


We have a chat application that runs fine when it is run via xcode on an iPhone 6 device with the latest firmware (9.0). Xcode is the latest one (7.0.1).

When we disconnect it from xcode and run it directly on the device, the app opens and then closes... We are looking for logs but there are no logs that register this particular crash.

Before upgrading this would not happen... Any idea what could be causing this?

Hi Mario Bernheim,

You can check your device logs in Window -> Device. Make sure you attached your device with xcode and Devices tab.

ALso you may put breakpoint and run app in development mode on your device to find exact problem.

Thanks & Regards,
