Application crashes when not running from Xcode but works fine when run from Xcode

Question

I have this strange issue. When I run application from Xcode (even on device), it works fine without any crash. But as and when I run it on device without Xcode, it crashes when I navigate back from one of the viewController. I am not able to get the reason for crash as I can't use log. Has someone experienced this before?

Answer 1

I recently experienced this after adding an MKMapView to the Storyboard. It ran perfectly when the device was attached to Xcode, but crashed when running without being connected to the computer.

The mistake I made was not checking the Embedded Frameworks.. the app was trying to load the MKMapView without having the MapKit framework imported.

The best way to diagnose this though, is to check your crash logs on the device you're using and you'll get a better understanding on what caused it
