Crashlytics : stuck on "Verifying Installation..." step

setDebugMode = YES

set below code before [Fabric with:@[ TwitterKit ]]; if applied for twitter kit. Or you can simply past below code in didFinishLaunchingWithOptions.

// Swift
Crashlytics().debugMode = true
Fabric.with([Crashlytics.self()])

// Objective-C
[[Crashlytics sharedInstance] setDebugMode:YES];
[Fabric with:@[[Crashlytics class]]];

Now build and run your app and check fabric UI window, it will move ahead to complete screen.

It seems silly but sometimes you need to make a code change (like a simple NSLog statement) to kick the verification.

I resolved the problem. I put my code in applicationDidFinishLaunching(application: UIApplication) instead of func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?)

If you're adding a new app you need to be an Admin of your organization but you may just be a User.
