iOS Question Release app quits silently and App Store finds it has crashed

[MitchBu]

In debug mode, my app works just fine in all aspects.

I submitted it to the App Store, and they find it crashed at launch. I confirmed that on my device.

  Guideline 2.1 - Performance - App Completeness We were unable to review your app as it crashed on launch. We have attached detailed crash

They joined three crash logs, but I have to confess being unable to read them. I tried add kscrash to the app, but it never sends out anything.

I will appreciate any help. TIA.

Here are the logs:
Crash log 1
Crash log 2
Crash log 3

Never release to the store before you tested your app in release mode.

Uninstall the store app and install a release build (with a non-store provision profile). Does it work?

No. It quits silently. I am at a loss to guess what is wrong.

That's good. It means that you can reproduce the error.

First step is to find out whether it crashes before your code runs. Comment the code in Application_Start and run it in release mode.
If it doesn't crash then you should use iReleaseLogger to monitor the logs: https://www.b4x.com/android/forum/t...-read-the-logs-in-release-mode.51164/#content
You can also track the logs with a local Mac computer, using Console app. The unfiltered logs are quite extensive. Filter them by your app name.
