🛠 How to use
The simplest way to use WKView is to call WebView with a URL String.
IMPORTANT: WebView must be presented inside a NavigationView.
import SwiftUI
import WKView
struct ContentView: View {
var body: some View {
NavigationView {
WebView(data: .url("https://rebeloper.com"), hidesBackButton: true)
}
}
}Note: Here we are hiding the Back button of the web view by setting hidesBackButton to false because the ContentView is the root view of our app.
🧳 Features
In the example below you can see one pushed and two presented WebViews. Take a look at the cool ways you may customize the WebView style.
import SwiftUI
import WKView
struct ContentView: View {
@State var isSheetPresented = false
var body: some View {
NavigationView {
VStack(spacing: 12) {
Divider()
// 1. Push a WebView with a url
NavigationLink("Push WebView", destination: WebView(data: .url("https://rebeloper.com"))
Button(action: {
isSheetPresented.toggle()
}, label: {
Text("Present WebView")
}).sheet(isPresented: $isSheetPresented, content: {
NavigationView {
// 2. Present WebView in a modal with hiding the back button
// WebView(url: "https://rebeloper.com", hidesBackButton: true)
// 3. Present a customized WebView in a modal
// WebView(url: "https://rebeloper.com",
// tintColor: .red,
// titleColor: .yellow,
// backText: Text("Cancel").italic(),
// reloadImage: Image(system"figure.wave"),
// goForwardImage: Image(system"forward.frame.fill"),
// goBackImage: Image(system"backward.frame.fill"))
// 4. Present WebView in a modal with a constant title
// WebView(url: "https://rebeloper.com", title: "WKView")
// 5. Present a webview with onNavigationAction and optional: allowedHosts, forbiddenHosts and credential
WebView(url: "https://rebeloper.com"//,
// allowedHosts: ["github", ".com"],
// forbiddenHosts: [".org", "google"],
// credential: URLCredential(user: "user", password: "password", persistence: .none)
){ (onNavigationAction) in
switch onNavigationAction {
case .decidePolicy(let webView, let navigationAction, let policy):
print("WebView -> \(String(describing: webView.url)) -> decidePolicy navigationAction: \(navigationAction)")
switch policy {
case .cancel:
print("WebView -> \(String(describing: webView.url)) -> decidePolicy: .cancel")
isSheetPresented = false
case .allow:
print("WebView -> \(String(describing: webView.url)) -> decidePolicy: .allow")
@unknown default:
print("WebView -> \(String(describing: webView.url)) -> decidePolicy: @unknown default")
}
case .didRecieveAuthChallenge(let webView, let challenge, let disposition, let credential):
print("WebView -> \(String(describing: webView.url)) -> didRecieveAuthChallange challenge: \(challenge.protectionSpace.host)")
print("WebView -> \(String(describing: webView.url)) -> didRecieveAuthChallange disposition: \(disposition.rawValue)")
if let credential = credential {
print("WebView -> \(String(describing: webView.url)) -> didRecieveAuthChallange credential: \(credential)")
}
case .didStartProvisionalNavigation(let webView, let navigation):
print("WebView -> \(String(describing: webView.url)) -> didStartProvisionalNavigation: \(navigation)")
case .didReceiveServerRedirectForProvisionalNavigation(let webView, let navigation):
print("WebView -> \(String(describing: webView.url)) -> didReceiveServerRedirectForProvisionalNavigation: \(navigation)")
case .didCommit(let webView, let navigation):
print("WebView -> \(String(describing: webView.url)) -> didCommit: \(navigation)")
case .didFinish(let webView, let navigation):
print("WebView -> \(String(describing: webView.url)) -> didFinish: \(navigation)")
case .didFailProvisionalNavigation(let webView, let navigation, let error):
print("WebView -> \(String(describing: webView.url)) -> didFailProvisionalNavigation: \(navigation)")
print("WebView -> \(String(describing: webView.url)) -> didFailProvisionalNavigation: \(error)")
case .didFail(let webView, let navigation, let error):
print("WebView -> \(String(describing: webView.url)) -> didFail: \(navigation)")
print("WebView -> \(String(describing: webView.url)) -> didFail: \(error)")
}
