iPhone 11 Pro Crash - arm64e

[AndrewEQ]

I had a test user report a crash very early in my app experience (they didn't get to main functionality yet), I noticed in the crash report that they were using a iPhone 11 Pro and that its architecture is arm64e, so I'm listing this here as I don't have an iPhone 11 Pro to test but I did find this article which may be the cause: https://developer.apple.com/documentation/security/preparing_your_app_to_work_with_pointer_authentication?language=objc

So I tried adding the "arm64e" to the architectures build setting and when I tried to archive, the following error(s) came up:

Undefined symbols for architecture arm64e:

Dependencies for arm64e has been added, so those linker errors should now be fixed. Hopefully we're one step closer to solving that crash... :)

Shweet man, hopefully 😄

Looks like Firebase is even waiting on Apple's official support: https://firebase.google.com/support/release-notes/ios#version_6210_-_march_24_2020
