I have this call in my loginViewController when Submit button is pressed:
let http = HTTPHelper()
http.post(\"http://someUrl.com/Login/userEmail/\\(username.
I was also having same issue, got resolved by taking reference from above answer. Thank you @Nate
var storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
var vc: UINavigationController = storyBoard.instantiateViewControllerWithIdentifier("AppViewController") as! UINavigationController
NSOperationQueue.mainQueue().addOperationWithBlock {
self.presentViewController(vc, animated: true, completion: nil)
}
