Hmm, odd you didn’t get his email. Try this out - turn on debug mode by adding this line before your Fabric.with line:
// Swift
Crashlytics().debugMode = true
Fabric.with([Crashlytics.self()])
// Objective-C
[[Crashlytics sharedInstance] setDebugMode:YES];
[Fabric with:@[[Crashlytics class]]];
Then build and run your app, cause a test crash, and send me the output on relaunch.
