Segue performing prematurely in if / else clause - ios

Question

The following code
class ViewController: UIViewController {
#IBOutlet weak var knock: UIButton!
#IBOutlet weak var label: UILabel!
var count: Int = 0
var unlocked: Int = 0
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func knockKnock(sender: UIButton) {
if count < 20 {
label.text = "Knocked \(count) times."
} else if count > 19 && count < 40 {
label.text = "Knocked \(count) times."
label.textColor = UIColor.randomColor()
} else if count > 39 && count < 100 {
label.text = "That's enough."
label.textColor = UIColor.blackColor()
} else if count > 99 && count < 102 {
label.text = "I wish you hadn't done that."
label.textColor = UIColor.redColor()
} else if count == 103 {
label.text = "Fine, come in."
label.textColor = UIColor.greenColor()
count = 126
unlocked += 1
}
if unlocked > 0 {
self.performSegueWithIdentifier("InsideHomeSegue", sender:sender)
}
count += 1
}
is prematurely performing the Segue in
if unlocked > 0 {
self.performSegueWithIdentifier("InsideHomeSegue", sender:sender)
}
The segue is performed immediately the first time the button is pressed, which I do not understand, as at that point the code should be unreachable behind a false if statement, since int unlocked is initialized with 0
I have had similar problems which turned out to be issues with XCode itself rather than my code; I have looked through all the files I can find referencing any variables or objects in Interface Builder, checked for naming inconsistencies, rogue outlets, etc.
I still have a very shaky understanding of Segues, and would appreciate any detailed help anyone can offer.
The larger if / else if block worked properly all the way up to the final increment until Segue code was added.
Originally the self.performSegueWithIdentifier("InsideHomeSegue", sender:sender) line was inside the else if count == 103 { block; var unlocked: Int was added to combat the Segue issue to no avail.
I've read through several pages of the XCode documentation on Segues, but haven't found anything else I can try.
It's possible I've overlooked something incredibly obvious, but regardless, thanks for reading.
Cheers
EDIT: I have checked all outlets, it's the only Segue in the project currently and it isn't hooked up anywhere else. The Segue is activated on a button press, not immediately on View load.

Answer 1

Just like what my comment said, You've connected the segue with your button, so that the segue will alway execute. It has nothing to do with if clause.
You should connect with the ViewController instead of connecting with a button

Answer 2

You have to connect your two ViewController with a segue, giving it an identifier. Then, you can trigger the segue in this way.
self.performSegueWithIdentifier("segue_name_identifier", sender: self)
Here how you can easily set your segue.
I hope that this will help you.
