Environment: OpenURL

@Environment(\.openURL) allows you to open URLs from your SwiftUI views.

What is @Environment(\.openURL)?

@Environment(\.openURL) is a property wrapper that provides a way to open URLs in your SwiftUI application. It gives you access to the OpenURL environment value, which you can use to present a URL in the appropriate way for the current platform.

struct ContentView: View {
    @Environment(\.openURL) var openURL

    var body: some View {
        Button("Open Website") {
            openURL(URL(string: "https://wesleydegroot.nl")!)
        }
    }
}

Custom OpenURLAction

You can also set a custom OpenURLAction for your views. This allows you to define how URLs should be handled when they are opened.

struct ContentView: View {
    var body: some View {
        Text(.init("Visit https://wesleydegroot.nl or [Play a sound](play://sound)"))
        .environment(\.openURL, OpenURLAction { url in
            if let scheme = url.scheme {
                if scheme == "play" {
                    // MusicPlayer.play(url)
                    return .handled
                }
            }
            return .systemAction
        })
    }
}
