Situation: A protocol A implements a protocol B. B has some @optional and some (@)required methods.
Question: Is it possible in protocol A to set a method from B to the opposite (opt. to reeq. and vv.)?
Cheers!
You probably mean protocol A extends/enhances B.
Making a required method optional would break existing code. You can use an implementation of A where B is needed, but you don’t provide a method that is required – so going from req. to opt. doesn’t make sense at all.
The other way around should work from a logical point of view. Have not tested it, though, but firing up your compiler should take less than a minute.
