The app looks awesome, and also served as my introduction to Hype Machine. How I haven't managed to hear of this service before is beyond me. Now I'm just sad I didn't know it existed until now.

Also great to hear that Swift development is going smoothly. I just started into learning it, and so far the strangest thing I've found is that I've learned a ton of Objective C by having to struggle through missing documentation/examples and having to learn the Obj C way of doing things and then translating them to Swift. It's been interesting.
