Getting cycle detected when trying to disable view based on published variable.

I have view model that keeps state around like so:

Code Block Swift
class FeedModel: ObservableObject {
    enum CurrenState: Equatable {
        case none
        case loading
        case error
        case done
    }
   private (set) var feed: RssFeed?
   @Published private (set) var currentState: CurrenState = .none

I did this to keep the model's loading state out of the view logic.

The idea is to disable the dialog and overlay a spinner. Like so:

Code Block swift
ZStack {
	VStack(alignment:.leading) {
		Text("Enter a feed address")
		TextField("", text: $text)
			 .frame(idealWidth: 300)
		 HStack {
			Spacer()
			Button("Cancel") {
				 isOpen = false
			}
			.keyboardShortcut(.cancelAction)
			Button("Add") {
				 model.load(address: text)
			 }
			 .keyboardShortcut(.defaultAction)
		}
	 }
	 .padding()
	 .disabled(model.currentState == .loading)
		
		if model.currentState == .loading {
			 ProgressView()
				.progressViewStyle(CircularProgressViewStyle())
		}
      }

The disable causes a cycle detected message. I actually get several of them. I don't want to move this code out of the model the model is managing some loading and knows what state it is in. If there is more to the loading then I want to be able to have the model mange the state.

The other idea is for this model to be reusable
