Swift has been out for over 7 months now, and I still learn new patterns and ways to do things all the time. And when I do know how to do something, I end up questioning if there isn't really a better way and if the better way is really better if the code isn't as readable (looking at you Generics and Custom Operators). Plus now with Swift 1.2, I'll have to re-learn and re-do what I "already know". It is sometimes overwhelming, but most of the time really challenging and fun.
