Objective-C doesn't really have named parameters. Objective-C has arguments spliced into the selector at each colon. (Of course, Swift inherits the selector->parameter limitation, but it goes to somewhat greater lengths to hide it.)

I'm pretty sure that Objective-C's named parameters actually have priority over all other forms, being from the nearly identical form they took in Smalltalk. It's only recently that languages have had the looser form of named parameters where their order doesn't matter and they're mostly just a way to disambiguate default arguments.

The Smalltalk form is actually more powerful, since it gives you a kind of multiple dispatch (a.la. C++ argument overloading) that would be quite expensive in a non-statically typed language otherwise.
