问题
I'm having problems with an app that we previously submitted to Apple for submission that they asked us to re-do a simple marketing issue (we needed to remove an image of an app screen which had third party apps).
Unfortunately, now when I have prepared the app for re-submission and I distribute it via Testflight the app crashes on launch. A subsequent launch works, however. This only happens with the Testflight build - when I do a Release build from Xcode using a production provisioning profile it works, and when I do a debug build it works. Thinking I must have made a mistake I pulled the exact commit from my repo for the previous submission, but it is now crashing the exact same way.
Only my ipad mini 2 reports the crash logs via the Xcode Organizer (my iPhone 6 does not), and they read like this (though I checked the box to include the debug symbols):

I can't figure out what's causing this, nor how I'll be able to test and confirm it's fix without re-submitting to Testflight and waiting.
I suspect this may be an Apple problem, but I'm nervous about re-submitting knowing there may be a crash in my app. Does anyone know what might cause this?
