    WKWebView, introduced in iOS 8 and OS X Yosemite which replaces UIWebView in UIKit and WebView in AppKit UI, it is used to open Safari browser outside the app. It loads web pages faster and more efficiently.

     

     

    So, in this blog we will learn how to Load an iFrame in WKWebView locally in an iOS App.

    Let's see the code Example:

    import UIKit
    import WebKit
    
    let bookData = BookData.sharedInstance
    let quizData = QuizData.sharedInstance
    
    class ViewController: UIViewController, WKUIDelegate {
    
        var webView: WKWebView! 
    
       override func loadView() {
    
    // implementing web view and giving delegate
    
          let webViewConfiguration = WKWebViewConfiguration()
            webView = WKWebView(frame: .zero, configuration: webViewConfiguration)
            webView.uiDelegate = self
            view = webView
        }
    
        override func viewDidLoad() {
            super.viewDidLoad()
    
            // saving it in a local directory
    
            let htmlPath = URL(fileURLWithPath:
                Bundle.main.path(
                    forResource: quizData.questions[quizData.curQuiz][quizData.curQuestion[quizData.curQuiz]].appendix,
                    ofType: "html",
                    inDirectory: "Bookshelf/Books/" + bookData.owned[bookData.bookSelected.ownedId].folder + bookData.owned[bookData.bookSelected.ownedId].version + "/quiz/appendix")!)
            webView.navigationDelegate = self
            webView.loadFileURL(htmlPath, allowingReadAccessTo: htmlPath) 
    
        }
    
        override func didReceiveMemoryWarning() {
            super.didReceiveMemoryWarning()
            // Dispose of any resources that can be recreated.
        }
    }
    
    extension ViewController: WKNavigationDelegate {
        // When page finishes loading then update ViewController title
    
        func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
            self.title = webView.title
        }
