Thank you David.

I do agree it generates a selector. My objection would be that there are no Objective-C methods named “getter” or “setter”.

>>   let firstNameGetter = #selector(get: Person.firstName)

>>   let firstNameGetter = #selector(getter: Person.firstName)

I could go along with you that it reads as an action, but I also think we could come up with tons of existing toolbox method names that would also read as actions.

Maybe I am hung up on insisting that the expression must be an actual name of an Objective-C method.
