Adjust UIActivityIndicatorView position in AlertView - Swift

I've been trying to adjust the position of IndicatorView inside UIAlertView, but it never works. i tried to set for loadingIndicator loadingIndicator.center = CGPointMake(alert.bounds.size.width / 2, alert.bounds.size.height - 50) but it didn't apply at all, take a look on this photo :

enter image description here

alert = UIAlertView(title: "Loading...", message: nil , delegate: nil, cancelButtonTitle: nil)
        loadingIndicator = UIActivityIndicatorView(frame: CGRectMake(50, 10, 37, 37))
        loadingIndicator.center = self.view.center
        loadingIndicator.hidesWhenStopped = true
        loadingIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.Gray
        loadingIndicator.startAnimating();

        alert.setValue(loadingIndicator, forKey: "accessoryView")
        loadingIndicator.startAnimating()
        alert.show();

You can use as many \n as necessary in the message to create the space.

In your ViewController.swift:

lazy var alertController: UIAlertController = {
    let alert = UIAlertController(title: "Loading", message: "\n\n", preferredStyle: .alert)
    alert.view.tintColor = .black
    let loading = UIActivityIndicatorView(frame: CGRect(x: 110, y: 35, width: 50, height: 50))
    loading.hidesWhenStopped = true
    loading.style = .gray
    loading.startAnimating();
    alert.view.addSubview(loading)
    return alert
}()

And usage:

// to show loading wheel
present(alertController, animated: true)

// to hide loading wheel
dismiss(animated: true)

Visual output:

Try following code: 

        var alert : UIAlertView = UIAlertView(title: "Loading...", message: nil , delegate: nil, cancelButtonTitle: nil)
        var viewBack:UIView = UIView(frame: CGRectMake(83,0,100,100))

        var loadingIndicator: UIActivityIndicatorView = UIActivityIndicatorView(frame: CGRectMake(50, 10, 37, 37))
        loadingIndicator.center = viewBack.center
        loadingIndicator.hidesWhenStopped = true
        loadingIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.Gray
        loadingIndicator.startAnimating();
        viewBack.addSubview(loadingIndicator)
        viewBack.center = self.view.center
        alert.setValue(viewBack, forKey: "accessoryView")
        loadingIndicator.startAnimating()
        alert.show();

I tried many times add custom view to UIAlertView ,many strange things happen. You can choose to use this library it is not as beautiful as the UIAlertView, it may solve you problem.
