Hi!
We've recently released an usual app-update, but suddenly got a bunch of crashes in App Store Connect and almost none in Firebase Crashlytics.
According to customer support, for some users the app insta-crashes. A white screen appears for a flash and then they're returned to the home screen. The app always insta-crashes, only a reinstall fixes it.
It makes sense while Crashlytics isn't reporting any crashes, because it doesn't even get a chance to run and upload the crash reports to their server.
The Xcode organizer does show a bunch of crashes, but with no stack trace. It just says MyApp: NO_CRASH_STACK
. Looking at the explicit 'xccrashpoint' in Finder reveals a couple of crash reports, that I've attached, but they're not that useful.
As far as I can tell, the app crashes while it's trying to load the Swift core, that's embedded in the app, but I'm not sure why that would cause a crash. Maybe it was supposed to use the library embedded in iOS (/usr/lib/swift/libswiftCore.dylib
)?
Any help would be greatly appreciated 🍺!
