Write a simple iPhone application / WebView / xCode Version 8.1 / swift

Hello, We need a simple iOS application to work on iPhones and iPads. We are on xCode Version 8.1 / swift. The application is a UIWebView / Page-wrap of a specific https site. What we need is to add these functions to the code: 1-Introduction First Page and "Enter App" Button. 1-Pull to refresh site (Refreshes the Http site) 2-Back Button (Like in html browser) 3-Forward Button (Like in html browser) 4-Refresh Button (Like in html browser) 5-Close Application Button (Confirmation Yes/No). 6-About Us Page We have the code running fine and it is opening the page on the simulator lacking the required functions above. as follows: ================== import UIKit class ViewController: UIViewController, UIWebViewDelegate { @IBOutlet weak var activityindicator: UIActivityIndicatorView! @IBOutlet weak var WebView: UIWebView! override func viewDidLoad() { [login to view URL]() // Do any additional setup after loading the view, typically from a nib. let url = URL(string: "[login to view URL]") let requestObj = NSURLRequest(url: url!); [login to view URL](requestObj as URLRequest); } override func didReceiveMemoryWarning() { [login to view URL]() // Dispose of any resources that can be recreated. } } ========================== Thank you,
