The state changes in the demo don't work for the (SwiftHI) icon button.

E.g, when I press the button, no image is shown.

The same problems exist with the disabled and selected states.

In the demo, the UIKit button and icon button don't change their appearance whether it's in selected state or not.

In the SwiftUI button there are some state changes not reflected:
Given:

• normal state: none
• highlighted state: text/Image ....
  When: the button is pressed
  Then: the button doesn't change
  Given:
• normal state: Image and attributed text
• highlighted: none
  When: the button is pressed
  Then: an icon is shown

And different combinations such as above

@michael-zimmermann,
Thank you for all your comments 💪

So, I update the code:

• I removed the manager, I replaced it with viewModel protocol (ButtonMainSUIViewModel) and two viewModel (IconButtonSUIViewModel & ButtonSUIViewModel) only for SwiftUI.
• There is no more multiple observable object on the views (just the viewmodel)
• On the demo app: it is no this is no longer possible to have no text in the button for the normal state.
• On the demo app: it is no this is no longer possible to have no image in the icon button for the ** for the normal state**.

I think the ControlStatus can remain as a struct
👍 Looks good
