I built a decently good-looking Asteroids clone using SpriteKit during the iOS 7 beta, and a pretty polished iOS 2048 implementation more recently. Both projects took a little longer than a weekend, and I don't consider myself a particularly talented developer. The iOS ecosystem has lots of tooling and libraries that make building simple games quite easy, so a month per game can be quite doable (depending on the kind of game, of course).
