Trust me and try this. I have run into this problem a few times. In Swift 2: dispatch_async(dispatch_get_main_queue(),{ self.performSegue(withIdentifier:mysegueIdentifier,sender: self) }) or for Swift 3: DispatchQueue.main.async { self.performSegue(withIdentifier: mysegueIdentifier,sender: self) } As discussed here and here.
self.navigationController.view.backgroundColor = [UIColor whiteColor]; I solved this problem by setting the background color of the navigation controller’s view.
So basically the segue was freezing because of the UITextView‘s I was using in the destinationViewController. The following fixed the issue: Delete all UITextView‘s Add new UITextView’s you must leave the default lorem imposed text and change this programmatically in the viewDidLoad() This was the fix for me, and from the research I have done … Read more
I was able to fix it by running “clean” under the “Product” menu in Xcode, and resetting the contents and settings in the simulator.

Here is how to set up a segue so that it can be called programmatically. Control drag from the ViewController icon in the first view controller to the second view controller. Click on the segue arrow between the two view controllers, and in the Attributes Inspector on the right, give the segue an Identifier (tableau … Read more

It has the following advantages: Can work anywhere in the view stack, not just the top view (not sure if this is realistically ever needed or even technically possible to trigger, but hey it’s in there). It doesn’t cause a pop OR transition to … Read more
Here is a quick summary of the segues and an example for each type. Show – Pushes the destination view controller onto the navigation stack, sliding overtop from right to left, providing a back button to return – if not embedded in a navigation controller it will be presented modally Example: Navigating in Settings, for … Read more
First, you have to have set up the segue in your storyboard and give it the appropriate identifier. (Click on the segue (left panel) and then click on Attributes (right panel). You can then link this to buttons or selection of table rows from your storyboard, or you can call it in code using performSegueWithIdentifier:sender:. … Read more
It’s possible in iOS 6 and later: You have to implement the method – (BOOL)shouldPerformSegueWithIdentifier:(NSString *)identifier sender:(id)sender In your view controller. You do your validation there, and if it’s OK then return YES; if it’s not then return NO; and the prepareForSegue is not called. Note that this method doesn’t get called automatically when triggering … Read more
