Well, I have no idea. I have heard rumours of Apple planning to invest on the language to run on other platforms and that would definitely be a step into this direction, similar to how Microsoft has done to F#. But there isn’t anything official and it is still a long road to go.

I guess Swift has some limitations in what directions it can go needing to maintain a decent level of compatibility with Objective-C. It is by no means going to be a perfect language, but on paper what they have put together looks quite impressive to me.

Thanks for the comment @jemfrost.

You are right, I didn’t cover implementing protocols with extensions, I just mentioned it still does not change the global semantics.

Regarding the argument names, as far as I know, they would be considered different if they expect distinct types. This is somehow what we covered in the last section. Different names were not enough, the compiler complains I am effectively redeclaring a function. Even though this helps alleviate name clashes, it still does not solve the issue of name polluting.
