uigesturerecognizer - Tap gesture (gesture began) not recognised in Swift

Question

UITapGestureRecogniser began state is not recognised, only ended is recognised.

override func viewDidLoad() {
     let tapgr = UITapGestureRecognizer(target: self, action: #selector(tapTrigger(recongizer:)))
     bottomBar.addGestureRecognizer(tapgr)
}

@objc func tapTrigger(recongizer: UITapGestureRecognizer){
        if recongizer.state == .began{
            print("recognised") // does not print
        }else if recogniser.state == .ended{
           print("ended") //prints
        }
}

What I am trying to do is highlight a view(not the view the recogniser is added) when a touch is recognised and unhighlight when it is cancelled.

Instead of using UITapGestureRecognizer you can use UILongPressGestureRecognizer to get the different state.

Like this:

let tapgr = UILongPressGestureRecognizer(target: self, action: #selector(tapTrigger(recongizer:)))
tapgr.minimumPressDuration = 0
bottomBar.addGestureRecognizer(tapgr)

@objc func tapTrigger(recongizer: UITapGestureRecognizer){
        if recongizer.state == .began{
            print("recognised") 
        } else if recongizer.state == .ended{
           print("ended") //prints
        }
}
