What are dependency injection approaches for WKWebView in Swift?

Dependency injection is a software design pattern that allows for the decoupling of components in your application. In the case of WKWebView in Swift, dependency injection can help test and manage web view instances more effectively. Here we discuss various approaches to implement dependency injection for WKWebView in Swift.

    // Example: Using Dependency Injection for WKWebView

    import UIKit
    import WebKit

    protocol WebViewProviding {
        func makeWebView() -> WKWebView
    }

    class DefaultWebViewProvider: WebViewProviding {
        func makeWebView() -> WKWebView {
            return WKWebView()
        }
    }

    class WebViewController: UIViewController {
        private let webViewProvider: WebViewProviding
        var webView: WKWebView!

        init(webViewProvider: WebViewProviding) {
            self.webViewProvider = webViewProvider
            super.init(nibName: nil, bundle: nil)
            self.webView = webViewProvider.makeWebView()
        }

        required init?(coder: NSCoder) {
            fatalError("init(coder:) has not been implemented")
        }

        override func viewDidLoad() {
            super.viewDidLoad()
            view.addSubview(webView)
            webView.frame = view.bounds
            if let url = URL(string: "https://www.example.com") {
                webView.load(URLRequest(url: url))
            }
        }
    }

    // Usage
    let webViewProvider = DefaultWebViewProvider()
    let webViewController = WebViewController(webViewProvider: webViewProvider)
