# init(handler:) Creates an action that opens a URL. ``` @MainActor @preconcurrency init(handler: @escaping (URL) -> OpenURLAction.Result) ``` ## Parameters `handler` The closure to run for the given URL. The closure takes a URL as input, and returns a [`OpenURLAction.Result`](/documentation/SwiftUI/OpenURLAction/Result) that indicates the outcome of the action. ## Discussion Use this initializer to create a custom action for opening URLs. Provide a handler that takes a URL and returns an [`OpenURLAction.Result`](/documentation/SwiftUI/OpenURLAction/Result). Place your handler in the environment using the [`environment(_:_:)`](/documentation/SwiftUI/View/environment(_:_:)) view modifier: ``` Text("Visit [Example Company](https://www.example.com) for details.") .environment(\.openURL, OpenURLAction { url in handleURL(url) // Define this method to take appropriate action. return .handled }) ``` Any views that read the action from the environment, including the built-in [`Link`](/documentation/SwiftUI/Link) view and [`Text`](/documentation/SwiftUI/Text) views with markdown links, or links in attributed strings, use your action. SwiftUI translates the value that your custom action’s handler returns into an appropriate Boolean result for the action call. For example, a view that uses the action declared above receives `true` when calling the action, because the handler always returns [`handled`](/documentation/SwiftUI/OpenURLAction/Result/handled). --- Copyright © 2026 Apple Inc.
