The problem is that we can write a String extension for example in any swift file in the project, the name of the file has nothing to do with the content of it. But for extensions … I think it is more ordered if we can see all Int extensions for example in same file. I don’t know how this could be done, maybe there is a way to even copy paste it automatically in a single file but for easier access I guess it would be nice to be able to find all extensions of a class in one place. You might not restrict it for anyone to write it in that single file, but you could automatically create a file for each class just to group all extensions of a class. Is that possible ?

I don't know how hard that'd be, but it sounds like a really neat feature for that new layer that Xcode's using to integrate with the compiler!
