I am trying translate the objective c code bellow to swift, i did so far but i get some error.. any help appreciate.
 dispatch_async(dispatch_get_main_queue(), ^{
        [self.window.rootViewController presentViewController:self.incomingCall animated:YES completion:nil];
in swift version i did in this way but i get an error :
dispatch_async(dispatch_get_main_queue(), { () -> Void in
            // Show the alert
           self.window?.rootViewController?.present(self.iincomingCall(), animated: true, completion: nil)
        })
