WKView is a lightweight library to present web content in your SwiftUI app with the help of WebKit.
Using Swift Package Manager, add it as a Swift Package in Xcode 11.0 or later, select File > Swift Packages > Add Package Dependency... and add the repository URL:
https://github.com/rebeloper/WKView.git
Download and include the WKView folder and files in your codebase.
- iOS 14+
- Swift 5
Import WKView into your View
import WKView
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.
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):
