So here I am just finished my first iPhone game made with SpriteKit, It has passed the review and will be released in few days. I'm now thinking about my next game and how I want to release it on Android platforms, the Android market is too big to ignore, but, unfortunately, it can't happen with SpriteKit. I really like working with SpriteKIt & Swift and I would have loved to continue working with it, but, unfortunately, I can't anymore and I have to start looking for an alternative and start learning another Framework/Language from scratch.
My question here is, why don't Apple separate SpriteKit from Xcode and release it as a Stand-alone app? make it run exclusively on Mac computers, but also, publish to Android. In my opinion, a move like this will see SpriteKit numbers sky-rocket because it already has so many features and after checking some alternatives, I consider it miles ahead all the other 2D frameworks/SDKs.
