I found a way to display activity Indicator with minimum code:

first of all import your UI Kit

import UIKit;

Then you have to initiate activity indicator

let activityIndicator:UIActivityIndicatorView = UIActivityIndicatorView();

Then just copy paste this functions below which are self explainatory and call them whereever you need them:

func startLoading(){
    activityIndicator.center = self.view.center;
    activityIndicator.hidesWhenStopped = true;
    activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.gray;
    view.addSubview(activityIndicator);

    activityIndicator.startAnimating();
    UIApplication.shared.beginIgnoringInteractionEvents();

}

func stopLoading(){ 

    activityIndicator.stopAnimating();
    UIApplication.shared.endIgnoringInteractionEvents();

}
