iOS: '[Fabric] It appears that “Crashlytics” is not a valid Fabric Kit [duplicate]

问题

I have updated the Crashlytics but still I am getting this error on launch:

Error: *** Terminating app due to uncaught exception 'FABException', reason: '[Fabric] It appears that "Crashlytics" is not a valid Fabric Kit. Please make sure you only pass Fabric Kits to [Fabric with:].'

Here is my code:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.
         Fabric.with([Crashlytics.self])
         return true
   }

Please try:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?)
-> Bool 
{
            // Override point for customization after application launch.
             Fabric.with([Crashlytics.class])  // <=========
             return true    
}
