Answer 1

it works in both SWITF 3 and 4

var activityIndicator = UIActivityIndicatorView()
var myView : UIView = UIView()

func viewDidLoad() {
    spinnerCreation()
}

func spinnerCreation() {

    activityIndicator.activityIndicatorViewStyle =  .whiteLarge

    let label = UILabel.init(frame: CGRect(x: 5, y: 60, width: 90, height: 20))
    label.textColor = UIColor.white
    label.font = UIFont.boldSystemFont(ofSize: 14.0)
    label.textAlignment = NSTextAlignment.center
    label.text = "Please wait...."

    myView.frame = CGRect(x: (UIScreen.main.bounds.size.width - 100)/2, y: (UIScreen.main.bounds.size.height - 100)/2, width: 100, height: 100)

    myView.backgroundColor = UIColor.init(white: 0.0, alpha: 0.7)
    myView.layer.cornerRadius = 5
    activityIndicator.center = CGPoint(x: myView.frame.size.width/2, y:  myView.frame.size.height/2 - 10)
    myView.addSubview(activityIndicator)
    myView.addSubview(label)

    myView.isHidden = true
    self.window?.addSubview(myView)
}

@IBAction func activityIndicatorStart(_ sender: Any) {
    myView.isHidden = false
    self.activityIndicator.startAnimating()
    self.view.isUserInteractionEnabled = false
    self.view.bringSubview(toFront: myView)
}

@IBAction func activityIndicatorStop(_ sender: Any)() {
    myView.isHidden = true
    self.activityIndicator.stopAnimating()
    self.view.isUserInteractionEnabled = true
}
