How to assign a shortcut on a button in SwiftUI on MacOS for iOS Project(Catalyst enabled)?

问题

I have a button on my view and I want to handle key events to perform something. How to do it? #if os(macOS) is false cause the project is mobile with enabled MacOS via Catalyst.

#if os(macOS)
extension Command {
    static let voiceSelectedText = Command(Selector("voiceSelectedText:"))
}
#endif

var body: some View {
    let button = Button(action: {
    }) {
        Text("Voice (Space)")
    }

    #if os(macOS)
        return button.onCommand(.voiceSelectedText) {

        }
    #else
        return button
    #endif

}

Update

#if targetEnvironment(macCatalyst)
// runs on macOS
#endif

#if os(iOS)
// works always
#endif

You should use .onCommand() modifier.
