Can't implement .onReceive(NotificationCenter.default.publisher(for...). What am I missing?

[lexum0]

I'm trying to implement an .onReceive() action but I keep getting errors like:
value of type 'Text' has no member 'onReceive'
value of type 'NotificationCenter' has no member 'publisher'

I even copied the code the Skip Showcase project but I'm still getting the errors. I have imported everything I can think of. Am I missing something or what could be interfering?
Any pointers would be great.
Thanks

Sample code:

Text("")
    .onReceive(NotificationCenter.default.publisher(for: UIApplication.didReceiveMemoryWarningNotification)) { _ in
        print("didReceiveMemoryWarningNotification")
    }

I updated the Showcase app and it has a comment saying Skip Fuse is not supported Skip Fuse does not support NotificationCenter publisher

What are the most suitable workarounds?
Will it be supported soon?
Thanks
