UIView touch event in controller

You will have to add it through code. First, create the view and add it to the hierarchy:

var myView = UIView(frame: CGRectMake(100, 100, 100, 100))
self.view.addSubview(myView) 

After that initialize gesture recognizer. Until Swift 2:

let gesture = UITapGestureRecognizer(target: self, action: "someAction:")

After Swift 2:

let gesture = UITapGestureRecognizer(target: self, action:  #selector (self.someAction (_:)))

Then bind it to the view:

self.myView.addGestureRecognizer(gesture)

    

Swift 3:

func someAction(_ sender:UITapGestureRecognizer){     
  // do other task
}
    

Swift 4 just add @objc before func:

@objc func someAction(_ sender:UITapGestureRecognizer){     
    // do other task
}

Swift UI:

Text("Tap me!").tapAction {
    print("Tapped!")
}
