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 ?

I've missed the read release notes, you can solve this problem by adding this lines

Workaround: In the Xcode project Build Settings, set “Other Swift Flags” to: -external-plugin-path $(SYSTEM_DEVELOPER_DIR)/Platforms/iPhoneOS.platform/Developer/usr/lib/swift/host/plugins#$(SYSTEM_DEVELOPER_DIR)/Platforms/iPhoneOS.platform/Developer/usr/bin/swift-plugin-server

	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"
	),
	]
	}
	}
