Disable Wkwebview for Opening Links to Redirect to Apps Installed on My Iphone

Prevent universal links from opening in `WKWebView`/`UIWebView`

sourcecode for WebKit:

static const WKNavigationActionPolicy WK_API_AVAILABLE(macosx(10.11), ios(9.0)) _WKNavigationActionPolicyAllowWithoutTryingAppLink = (WKNavigationActionPolicy)(WKNavigationActionPolicyAllow + 2);

if you are using WKWebView, just use WKNavigationActionPolicyAllow + 2 instead of WKNavigationActionPolicyAllow

Present iTunes link inside of a WebView (prevent redirect)?

A possible work-around is to request the desktop-mode of the website, which will display the intended content instead of redirecting you.

Using UIWebView:

UserDefaults.standard.register(defaults: ["UserAgent": "Custom-Agent"])

Make sure you register this custom agent before loading the URLRequest. Note that this method would apply for all UIWebView objects in your application. If you want just some specific views to load the desktop version, you'll need to use WKWebView as follows, seeing as it allows you to use a custom agent per object.

Using WKWebView:

First, you must import WebKit. Then, initialize it like this:

let url = URL(string: "https://itunes.apple.com/us/album/burn-that-broken-bed/id1120162623?i=1120163074&uo=4")!
let wkWebView = WKWebView(frame: self.view.frame, configuration: WKWebViewConfiguration())
wkWebView.uiDelegate = self     // Optional line - must conform to WKUIDelegate
// the line below specifies the custom agent, which allows you to request the desktop version of the website
wkWebView.customUserAgent = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.109 Safari/537.36"
wkWebView.load(URLRequest(url: url))
self.view.addSubview(wkWebView)

Update: (Integrating WKWebView)

Unfortunately, you can't add a WKWebView in IB as of XCode 8, so you'll have to add it programmatically. The good news here is that you can use the frame of the UIWebView you created in IB to slightly ease the programmatic instantiation of the WKWebView object

Check this out: (untested code)

// for ease of use
extension WKWebView {
    func setDesktopMode(on: Bool) {
        if on {
            customUserAgent = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.109 Safari/537.36"
            return
        }
        customUserAgent = nil
    }
}

And in your custom cell file

class MyCustomCell: UICollectionViewCell {
    var wkWebView: WKWebView!    // add this line
    @IBOutlet weak var webView: UIWebView!     // the one you created in IB
}

Then in your UIViewController

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CellIdentifier", for: indexPath) as! MyCustomCell

    let url = URL(string: "url here")!

    cell.wkWebView = WKWebView(frame: cell.webView.frame, configuration: WKWebViewConfiguration())   // using the webView's frame that was created in IB
    cell.wkWebView.uiDelegate = self     // Optional line - must conform to WKUIDelegate
    cell.wkWebView.setDesktopMode(on: true)  // true = loads desktop mode (for your iTunes URLs)
    cell.wkWebView.load(URLRequest(url: url))

    return cell
}
