Swift 3 WKWebView 'URLRequest'; did you mean to use 'as' to explicitly convert? ( BUG )

Question

Hello when I use WKWebView codes with Swift 3 gives me this error

'URLRequest'; did you mean to use 'as' to explicitly convert?

I think this is bug I need help or ideas ? My codes under below Thanks

import UIKit
import WebKit

class SocialsViewController: UIViewController, WKNavigationDelegate {


    var webView = WKWebView()


    override func viewDidLoad() {
        super.viewDidLoad()

        let url = NSURL(string: "https://facebook.com")!
        webView.loadRequest(NSURLRequest(url: url))
        webView.allowsBackForwardNavigationGestures = true


    }


}

You need to unwrap the value by using either `!` or `?` – Jigar Tarsariya Jun 20 '16 at 11:19 — Jigar Tarsariya, Jun 20 '16 at 11:19
@JigarTarsariya I did everything with Xcode. – SwiftDeveloper Jun 20 '16 at 11:20 — SwiftDeveloper, Jun 20 '16 at 11:20
Have you tried with `UIWebView` only? – Jigar Tarsariya Jun 20 '16 at 11:21 — Jigar Tarsariya, Jun 20 '16 at 11:21

Use URL and URLRequest instead:

let url = URL(string: "https://facebook.com")!
webView.load(URLRequest(url: url))

This is quite similar to https://stackoverflow.com/a/37812485/2227743: you either use NSURL and have to downcast it as URL, or you directly use the new Swift 3 structs.

If you follow the error message, your example would become:

let url = NSURL(string: "https://facebook.com")!
webView.load(URLRequest(url: url as URL))

It could be even worse:

let url = NSURL(string: "https://facebook.com")!
webView.load(NSURLRequest(url: url as URL) as URLRequest)

All this works but of course it's much better to start using URL and URLRequest in Swift 3, without using all this downcasting.

Try this one

 let myUrl = URL(string: "https://facebook.com")!
    webView.loadRequest(URLRequest(url:myUrl));

No. In Swift 3, it's `load`, not `loadRequest`, and I've already answered with a correct solution. – Eric Aya Nov 30 '16 at 13:46
Yes! Mr Eric you already provide correct solution. I just change name to differentiate argument "url" and variable of URL struct "myUrl". which is little confusing for freshers. Thanks – Nirmal Bajpai Dec 01 '16 at 08:37
