How can I implement a swipe gesture to change view to and fro?
The best example I've seen so far is the Soundcloud application but I couldn't figure out how to make it work.

This tutorial might be helpful to you: http://www.avocarrot.com/blog/implement-gesture-recognizers-swift/
Basically, you'll need to add a gesture recognizer to your view that listens for swipe gestures. Then when it detects a swipe, push to the next view.
Use this code...
override func viewDidLoad() {
super.viewDidLoad()
var swipeRight = UISwipeGestureRecognizer(target: self, action: "respondToSwipeGesture:")
swipeRight.direction = UISwipeGestureRecognizerDirection.Right
self.view.addGestureRecognizer(swipeRight)
}
func respondToSwipeGesture(gesture: UIGestureRecognizer) {
if let swipeGesture = gesture as? UISwipeGestureRecognizer {
switch swipeGesture.direction {
case UISwipeGestureRecognizerDirection.Right:
println("Swiped right")
//change view controllers
let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
let resultViewController = storyBoard.instantiateViewControllerWithIdentifier("StoryboardID") as ViewControllerName
self.presentViewController(resultViewController, animated:true, completion:nil)
default:
break
}
}
}
override func viewDidLoad()
{
super.viewDidLoad()
let leftSwipe = UISwipeGestureRecognizer(target: self, action: #selector(handleSwipes(_:)))
let rightSwipe = UISwipeGestureRecognizer(target: self, action: #selector(handleSwipes(_:)))
leftSwipe.direction = .left
rightSwipe.direction = .right
view.addGestureRecognizer(leftSwipe)
view.addGestureRecognizer(rightSwipe)
}
@objc func handleSwipes(_ sender: UISwipeGestureRecognizer)
{
if sender.direction == .left
{
print("Swipe left")
// show the view from the right side
}
if sender.direction == .right
{
print("Swipe right")
// show the view from the left side
}
}
You can a UISwipeGestureRecognizer to your UIView and add to this gesture a target and an action to perform when the gesture occurs
