Bit of a tangent: I noticed in the screenshots a Jetbrains-like logo for an IDE called AppCode. Been considering tinkering with Swift/Obj-C development for a bit. I know XCode's reputation as being awful though, so it sounded great that Jetbrains had a product for this. To my dismay they discontinued it[0] last December. There is at least a freemium/community plugin for Swift support on other IDEs[1].
