I use this in C#:

delegate StateDelegate StateDelegate();
StateDelegate state;

What is the Silver equivalent?

I use that for state machine.
The state is a method.
The method return next state or null.

Thanks

Hmm, good Q. I don’t believe you can declare this using Swift’s block/delegate syntax.

Thanks for the confirmation.
Looks like I need to back to old style, switch state using enum.
