Isn't this more a use case for function attributes, rather than decorators? Decorators seem like overkill in this case.

I don't fully understand the issues, but I believe that the declaration is more like a statement than a mere declaration (very similar to all other "declarations" in Python).

In the specific case, I believe declaring the Objective-C signature also performs some kind of registration of the function with the Objective-C run-time. This cannot be done with function attributes; you would still need to invoke a do_register()/generate_wrappers() functions at some point.

Even if this is a mere declaration, function attributes would harm readability: they would have to go after the function, whereas you want the Objective-C signature close to the Python signature.
