Fully functional, SwiftUI-ready WebView for iOS 13+ and MacOS 10.15+. Actions and state are both delivered via SwiftUI @Binding
s, making it dead-easy to integrate into any existing SwiftUI View.
This is a branch from https://github.com/globulus/swiftui-webview to add support for preferredContentMode.
This component is distributed as a Swift package. Just add this URL to your package list:
https://github.com/sethgecko13/swiftui-webview
You can also use CocoaPods:
pod 'SwiftUIWebView', '~> 1.0.9'
-
Pass the config parameter to optionally set various web view properties:
javaScriptEnabled
allowsBackForwardNavigationGestures
allowsInlineMediaPlayback
mediaTypesRequiringUserActionForPlayback
isScrollEnabled
isOpaque
backgroundColor
configuration.defaultWebpagePreferences.preferredContentMode
-
The action binding is used to control the WebView - whichever action you want it to perform, just set the variable's value to it. Available actions:
idle
- does nothing and can be used as the default value.load(URLRequest)
- loads the given request.loadHTML(String)
- loads custom HTML string.reload
goBack
goForward
evaluateJS(String, (Result<Any?, Error>) -> Void)
- evaluate any JavaScript command in the web view and get the result via the callback.
-
The state binding reports back the current state of the WebView. Available data:
isLoading
-true
if the WebView is currently loading a page.pageURL
- the URL of the currently loaded page, ornil
if it can't be obtained.pageTitle
- the title of the currently loaded page, ornil
if it can't be obtained.pageHTML
- the HTML code of the page content. SethtmlInState: true
inWebView
initializer to receive this update.error
- set if an error ocurred while loading the page,nil
otherwise.canGoBack
canGoForward
-
The optional restrictedPages array allows you to specify hosts which the web view won't load.
-
htmlInState dictates if the
state
update will containpageHTML
. This is disabled by default as it's a costly operation. -
Optional schemeHandlers allow you to invoke a custom callback whenever the user navigates to a site with the given scheme.
