Delegate Conforming to Multiple Protocols in Swift 3

Delegates in Swift can conform to multiple protocols by using the & operator. For example:

protocol AbcDelegate {
}

protocol XyzDelegate {
}

class Sample {
  var delegate: AbcDelegate & XyzDelegate
 
  init(delegate: AbcDelegate & XyzDelegate) {
    self.delegate = delegate
  }
}

class MyViewController: UIViewController, AbcDelegate, XyzDelegate {

  func doSomething() {
    let sample = Sample(self)
  }
}
