It's been fun following Brent Simmons' Swift Diary, where he documents his journey of learning Swift after doing Objective-C for, like, 20 years. Mostly he's been writing about the difficulties he's faced, but this latest post is quite a bit more positive.
But here’s what happens now. Sometimes I go to write some Objective-C code and I sigh at the effort — because I know the Swift version is half as long. I sigh at jumping to the top of the file and adding an import, and I sigh at switching to the .h file and adding a method.
And that’s where I am now — starting to feel that boost in productivity with Swift, and getting a little bit addicted to it.
