How do I change the user agent in my WebView using Swift 4.2?

Question

I'm struggling with changing the user agent on my project using the latest Xcode version with swift 4.2 .

I want to pretend that I'm a Mac visiting a specific website. Please edit this code and post it in the comments

Here's my code so far.

class ViewController: UIViewController {
    @IBOutlet weak var webview: WKWebView!

    override func viewDidLoad() {
        super.viewDidLoad()

        let userAgent = "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.116 Safari/537.36 Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.10"
        let myURL = NSURL(string: "http://website.com")
        let myURLRequest:NSURLRequest = URLRequest(url: myURL! as URL) as NSURLRequest
        webview.load(myURLRequest as URLRequest)
        myURLRequest.setValue(userAgent, forKey: "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2227.1 Safari/537.36")

        webview.load(URLRequest(url: myURL! as URL))
    }
}

If I build it I receive this error:

![Error][2].

WKWebView has a property called customUserAgent exactly for this purpose:

let customUserAgent = "Mozilla/5.0 ..." // Your custom user agent string goes here"
webView.customUserAgent = customUserAgent
