Open Radar

 
Summary:
As discussed here https://forums.developer.apple.com/thread/74872 , on Xcode 8.3 the playgrounds don't detect any kind of gestures (swipes, taps etc)

Steps to Reproduce:
1. Open attached Xcode playground 
2. Open Assistant Editor
3. Run the playground
4. Tap/click on the view on the Assistant Editor

Expected Results:
The Tap Gesture Recognizer to be called (in this case the recognizer would just print "tap" on the console)

Actual Results:
The Tap Gesture recognizer is not called (works fine on Xcode 8.0)

Version:
Xcode 8.3

Configuration:
MacBook Pro (13-inch, Mid 2012) non retina

###
This is the playground that I've attached:

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {
  override func viewDidLoad() {
    super.viewDidLoad()
    view.backgroundColor = .white
    
    let gesture = UITapGestureRecognizer(target: self, action: #selector(tapHandler))
    view.addGestureRecognizer(gesture)
  }
  
  func tapHandler() {
    print("tap")
  }
}

let controller = ViewController()
PlaygroundPage.current.liveView = controller
