It&#x27;s [weird] that the app can run well without any issues when debugging from Xcode but it crashes if I lunch the app by clicking the icon from my phone.Agreed, but that doesn’t fundamentally change my advice.  Earlier I wrote:Such crashes are usually accompanied by a log message that gives you hints as to the actual problem.If you run the app from the Home screen than these log messages end up in the system log, which you can monitor using the Console app on macOS.Share and Enjoy — Quinn “The Eskimo!” Apple Developer Relations, Developer Technical Support, Core OS/Hardware let myEmail &#x3D; "eskimo" + "1" + "@apple.com"

This crash indicates that there was a problem instantiating the objects in your nib.  Such crashes are usually accompanied by a log message that gives you hints as to the actual problem.  I recommend that you go looking for that.  If you run your app from Xcode, the message should show up in the Console area.Share and Enjoy — Quinn “The Eskimo!” Apple Developer Relations, Developer Technical Support, Core OS/Hardware let myEmail &#x3D; "eskimo" + "1" + "@apple.com"

Hi Eskimo,Thx for your reply. It&#x27;s wired that the app can run well without any issues when debugging from Xcode but it crashes if I lunch the app by clicking the icon from my phone.
