Cannot assign to property: "description" property is immutable error with ( leftSwipe.description = .Left)

Question

I am following along a YouTube video tutorial on Swipe Gestures. The code I am writing is exactly as being shown in the tutorial, but I an getting the error (Cannot assign to property: "description" property is immutable error) on the line (leftSwipe.description = .Left)

override func viewDidLoad() {
        super.viewDidLoad()

var leftSwipe = UISwipeGestureRecognizer(target: self, action: Selector("handleSwipes"))

leftSwipe.description = .Left
 }

The tutorial author is writing it exactly the same way but not getting the error I am getting. I would be grateful for help. Link to the YouTubeVideo Tutorial I am following is: https://www.youtube.com/watch?v=9r1UFNeVuFA

Answer 1

is not description

 leftSwipe.description = .Left

it is direction

leftSwipe.direction = UISwipeGestureRecognizerDirection.Left 

// or use 

 leftSwipe.direction = .Left 

Answer 2

Not description, you're using the wrong property name, it should be direction.

Answer 3

override func viewDidLoad() 
{      
    super.viewDidLoad()

    var leftSwipe = UISwipeGestureRecognizer(target: self, action:     
    Selector("handleSwipes"))

    leftSwipe.direction = .Left
 }

Answer 4

use

 leftSwipe.direction = .Left
