Looks nice. What is your opinion on Swift now that you've used it for a project?
But for a new app, I would recommend Swift to anyone, it's light, and readable, I really like it.
Kids these days... We had to learn new languages with no "syntax highlighting", no "completion engine", no tutorials, no reference sites and no internet in general. If we were lucky we had some kind of printed manual -- not always.
I hope that Xcode/Swift gets better in the debugging department soon. NSLog() is a rough way to see values. It's just so 1996.
Well, XCode also has the Swift Playground, with live values updating next to your code etc. Java/IntelliJ don't have that (of course XCode's implementation is beta too, and might not work on some cases).
