A simple SwiftUI Webview

Webview.swift

import SwiftUI
import WebKit

struct ContentView: View {
    var body: some View {
        Webview(url: URL(string: "https://google.com")!)
    }
}

struct Webview: UIViewRepresentable {
	let url: URL

	func makeUIView(context: UIViewRepresentableContext<Webview>) -> WKWebView {
		let webview = WKWebView()

		let request = URLRequest(url: self.url, cachePolicy: .returnCacheDataElseLoad)
		webview.load(request)

		return webview
	}

	func updateUIView(_ webview: WKWebView, context: UIViewRepresentableContext<Webview>) {
		let request = URLRequest(url: self.url, cachePolicy: .returnCacheDataElseLoad)
		webview.load(request)
	}
}

How do I catch if the URL changed using your approach?

Something like that should work for navigation handling:

import SwiftUI
import WebKit

struct SAWebView: View {
    var body: some View {
        Webview(url: URL(string: "https://google.com")!)
    }
}

struct Webview: UIViewRepresentable {
    let url: URL
    let navigationHelper = WebViewHelper()

    func makeUIView(context: UIViewRepresentableContext<Webview>) -> WKWebView {
        let webview = WKWebView()
        webview.navigationDelegate = navigationHelper

        let request = URLRequest(url: self.url, cachePolicy: .returnCacheDataElseLoad)
        webview.load(request)

        return webview
    }

    func updateUIView(_ webview: WKWebView, context: UIViewRepresentableContext<Webview>) {
        let request = URLRequest(url: self.url, cachePolicy: .returnCacheDataElseLoad)
        webview.load(request)
    }
}

class WebViewHelper: NSObject, WKNavigationDelegate {
    func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
        print("webview didFinishNavigation")
    }
    
    func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {
        print("didStartProvisionalNavigation")
    }
    
    func webView(_ webView: WKWebView, didCommit navigation: WKNavigation!) {
        print("webviewDidCommit")
    }
    
    func webView(_ webView: WKWebView, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) {
        print("didReceiveAuthenticationChallenge")
        completionHandler(.performDefaultHandling, nil)
    }
}

Hey man, this is great, thanks! How would you access the currently loaded URL?

Great way to display WebView in SwiftUI, thanks!
