What I want:

I'm trying to figure out how to set the minimum and maximum zoom onWKWebView.
I've searched through a lot of people who asked similar questions but no solutions has worked in my code.
If there is no option to set the minimum and maximum zoom, I would like to know how to disable zoom on WKWebView entirely.

    import UIKit

import WebKit



class CalendarViewController: UIViewController, WKNavigationDelegate, WKUIDelegate {



    var webView: WKWebView!

    @IBOutlet weak var containerView: UIView!

    @IBOutlet weak var progressView: UIProgressView!



    override func loadView() {

        super.loadView()

    }



    override func viewDidLoad() {

        super.viewDidLoad()





        progressView.setProgress(0.1, animated: true)



        let webConfiguration = WKWebViewConfiguration()

        webConfiguration.applicationNameForUserAgent = "Version/8.0.2 Safari/600.2.5"



        let customFrame = CGRect.init(origin: CGPoint.zero, size: CGSize.init(width: 0.0, height: self.containerView.frame.size.height))



        webView = WKWebView(frame: customFrame, configuration: webConfiguration)

        webView.uiDelegate = self

        webView.navigationDelegate = self

        self.containerView.addSubview(webView)

        self.webView.translatesAutoresizingMaskIntoConstraints = false



        self.view.addConstraint(NSLayoutConstraint(item: webView, attribute: .trailing, relatedBy: .equal, toItem: self.containerView, attribute: .trailing, multiplier: 1, constant: 0))

        self.view.addConstraint(NSLayoutConstraint(item: webView, attribute: .leading, relatedBy: .equal, toItem: self.containerView, attribute: .leading, multiplier: 1, constant: 0))

        self.view.addConstraint(NSLayoutConstraint(item: webView, attribute: .top, relatedBy: .equal, toItem: self.containerView, attribute: .top, multiplier: 1, constant: 0))

        self.view.addConstraint(NSLayoutConstraint(item: webView, attribute: .bottom, relatedBy: .equal, toItem: self.containerView, attribute: .bottom, multiplier: 1, constant: 0))







        progressView.sizeToFit()

        progressView.progressTintColor = UIColor(red: 255/255, green: 204/255, blue: 0/255, alpha: 1.0)



        webView.backgroundColor = UIColor.clear

        webView.backgroundColor = UIColor(red: 0.0196, green: 0.4, blue: 0.2902, alpha: 1.0)

        webView.isOpaque = false



        webView.load(URLRequest(url: URL(string: "https://jwelsh19.wixsite.com/website-1")!))



        self.webView.addObserver(self, forKeyPath: "estimatedProgress", options: .new, context: nil)



        //create a new button

        let button = UIButton.init(type: .custom)

        //set image for button

        button.setImage(UIImage(named: "LogoMin"), for: UIControlState.normal)

        //add function for button

        button.addTarget(self, action: #selector(SportsViewController.acButtonPressed), for: UIControlEvents.touchUpInside)

        //set frame

        button.frame = CGRect(x: 0, y: 0, width: 32, height: 32)

        button.widthAnchor.constraint(equalToConstant: 32.0).isActive = true

        button.heightAnchor.constraint(equalToConstant: 32.0).isActive = true



        let barButton = UIBarButtonItem(customView: button)

        //assign button to navigationbar

        self.navigationItem.leftBarButtonItem = barButton



        let refreshControl = UIRefreshControl()

        refreshControl.addTarget(self, action: #selector(reloadWebView(_:)), for: .valueChanged)

        refreshControl.tintColor = UIColor.white

        webView.scrollView.addSubview(refreshControl)

    }



    @objc func reloadWebView(_ sender: UIRefreshControl) {

        webView.reload()

        sender.endRefreshing()

    }



    override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {

        if keyPath == "estimatedProgress" {

            print(self.webView.estimatedProgress);

            self.progressView.progress = Float(self.webView.estimatedProgress);        }

    }



    @IBAction func home(_ sender: UIButton) {

        let myURL = URL(string: "https://jwelsh19.wixsite.com/website-1")

        let myRequest = URLRequest(url: myURL!)

        webView.load(myRequest)

    }



    @IBAction func refresh(_ sender: UIButton) {



        webView.reload()



    }



    //This method will call when you press button.

    @objc func acButtonPressed() {



        print("button is pressed")

        self.performSegue(withIdentifier: "Account", sender: self)

    }
