TipKitMacros throws an error

Hi folks, I'm trying to implement TipKits to understand more better but I'm facing an error while trying to use @Parameter macro.

Here is the sample code that I've tried as showed on instruction videos below

struct FavoriteLandmarkTip: Tip {
    @Parameter
    static var isLoggedIn: Bool = false

    var title: Text {
        Text("Save as Favourite")
    }

    var message: Text? {
        Text("Your favorite landmarks always appear at the top of the list.")
    }

    var asset: Image? {
        Image(systemName: "star")
    }

    var actions: [Action] {
        [
            Tip.Action(
                id: "learn-more",
                title: "Learn More"
            ),
        ]
    }
}

But I'm getting this error for isLoggedIn property

External macro implementation type 'TipKitMacros.ParameterMacro' could not be found for macro 'Parameter(isTransient:customID:)'; the type must be public and provided by a macro target in a Swift package, or via '-plugin-path' or '-load-plugin-library'

Could you help me to solve this problem ?
