Application failed with EXC_SOFTWARE / UNCAUGHT_NS_EXCEPTION

Question

I get Firebase Crash reports and I'm not sure what causes the crash. I could not replicate the error by testing it in Xcode, but the crash affects several different users, so I know that this is not a single error of a particular device. Below is all that I know about what happens during the crash. However, obviously, since this is being reported through Firebase crash reports, I only have so much information.

• All crashes come from some iPad device, which may or may not be a coincidence.

• I can tell from the event logs that the same crash on different screens for different users, so the crash is probably somewhere in the AppDelegate class, but I'm not sure which problem would occasionally occur this crash.

• The only point in the crash trace that I recognize as something I encoded is main (AppDelegate.swift:15), however, the fifth line in my AppDelegate file is just a declaration of the AppDelegate class, for example:

  class AppDelegate: UIResponder, UIApplicationDelegate {

Therefore, I am not sure what might be wrong in this section.

Let me know if there is any specific information that you think may be related to the failure, and I will try to provide it where possible.
