PerformSegueWithIdentifier does not work

Question

I am trying to use use self.performSegueWithIdentifier to change the view on the Storyboard when a JSON file loaded remotely. For this I am using the Swift Class \"

Answer 1

Edited: (I've put a slightly different answer in the first place)

Basically, the problem is that you have entered a side queue

and by just getting the main queue and invoking the segue in it, it will work quite fine.

dispatch_async(dispatch_get_main_queue()) {
   self.performSegueWithIdentifier("toView2", sender: self)
}

Hope it works
