In order to use an unwind segue, you start by setting up a method in the destination view controller. @IBAction func unwind(segue: UIStoryboardSegue) { // unwind } Note, that this method is placed in the destination view controller. The view controller being unwound to. From here, we need not the...
Performwithsegue and programatically switching views - Objective-C
objective-c,segue,viewcontroller
OK, what you are doing here is bypassing the segue completely. You need to do something like this... - (IBAction)Akkoord:(id)sender { [self performseguewithidentifier:@"nextcontroller"] } This is all you need to do. The segue will then create the nextController for you and then the code inside prepareForSegue will pass the variables...
Specify direction of “show” (push) segue
I don't believe there is a built in method for achieve that, however you could use Custom Transitions, which were introduced in iOS7. There are plenty of great tutorials out there, I've added some links below and some sample code demonstrating how you could slide the new view controller down...

How to both dismiss and deinit a (Game)ViewController using swift?
ios,xcode,swift,sprite-kit,segue

Swift - How to properly architect buttons in MVC?
ios,swift,uiview,uibutton,segue
button.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside) button.addTarget(self, action: "saveButton:", forControlEvents: UIControlEvents.TouchDown) The normal thing is that the button should be sending messages to its view controller. That is the standard MVC thing to do - indeed, that is the VC in MVC (the View is letting the Controller know there has...

iOS programmatically triggered segue is performed multiple times on success

Found it: the problem was that the controller kept "listening" even when there was a failed message being sent because of the [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(logInAttemptComplete:) name:@"logInNotification" object:nil]; being inside the function of pressing the log in button. All I had to do was add the [[NSNotificationCenter defaultCenter] removeObserver:self name:@"logInNotification"...

How use adaptive size classes to determine which segue to use?
