How to send Swipe Action to UIView in Swift

Question

I am trying to clone Tinder, have done with swipe left (dislike person) and right (like person) by Yalantis/Koloda (https://github.com/Yalantis/Koloda). I also have two images for button like/dislike. I wish my mainView will swipe Left/Right when I touch like/dislike image.

let likeImageTap = UITapGestureRecognizer(target: self, action: #selector(HomeViewController.sendSwipeRightAction))
        likeImage.isUserInteractionEnabled = true
        likeImage.addGestureRecognizer(likeImageTap)

How should I put in this func?

    @objc func sendSwipeRightAction() {
        
    }

This is my protocols

extension HomeViewController: KolodaViewDataSource, KolodaViewDelegate {
   //...
       func koloda(_ koloda: KolodaView, didSwipeCardAt index: Int, in direction: SwipeResultDirection)
    {
        if direction == .left {
          //...
          print ("swipe left")
        }
        if direction == .right {
          //...
          print("swipe right")
        }
    }
}

This is my view

@IBOutlet var mainView: KolodaView!

I try to use this func, then call it when image tapped, so I can do what I want same as swipe, but the view not change to next image.

public func swipe(_ direction: SwipeResultDirection, force: Bool = false)
 { 
//..
}

So I want to send swipe action to the view, example:

mainView.sendActions(for: .swipeLeft)

How should I do? Thanks for your suggestion.

Answer 1

There is code in example

kolodaView.swipe(.left)
kolodaView.swipe(.right)

your code will be like this

@objc func sendSwipeRightAction() {
        mainView.swipe(.right)
    }
