import UIKit
import PlaygroundSupport
class Responder : NSObject {
    func action() {
        print("Button pressed!")
    }
}

let containerView = UIView(frame: CGRect(x: 0.0, y: 0.0, width: 300.0,    height: 600.0))
PlaygroundPage.current.liveView = containerView
let responder = Responder()

let button = UIButton(frame: CGRect(x: 0, y: 0, width: 50, height: 50))
button.backgroundColor = UIColor.green
button.setTitle("TEST", for: .normal)
button.addTarget(responder, action: #selector(Responder.action), for: .touchUpInside)
containerView.addSubview(button)
