App crashes after two weeks on iOS



I recently just completed my Ionic app and deployed it on my iPhone for testing. The app runs fine for a week or two, and then suddenly just stops working.

When I press the app icon, the app opens, app splash screen is displayed, then the app just crashes with no error message, andI am taken back to the home screen of my phone.

I have not had this issue with android yet (still testing). Does anyone know what could be causing this problem?
