I'm curious how far along everyone is in transitioning to Swift. Personally, I've played with Swift but I haven't actually used it in any projects. From time to time when writing Obj-C code, I ask myself why I'm still writing Obj-C code and haven't moved to Swift, yet. IE, today I was looking for how to use map on an NSArray in Obj-C. There's no great answer for it. Of course, Swift just has map as a built in function for Array. And I don't have a reason for why not. I guess I'm still using it for the same reason I'm still using Python 2 - I feel like there's a big hurdle in moving forward. I feel like it'll be easier to keep dealing with the pain of using Obj-C for now and deal with going over that hurdle later. But maybe this just means that the hurdle is only going to grow larger. IDK, has anyone jumped over the hurdle yet? Should I set aside the time to go over all my existing Obj-C code in the project and shift it over to Swift? Or should I wait until later to do that?
