I made a cute little particle generating app for our youngest daughter using SpriteKit. It’s best when played on an iPad but an iPhone works too. Looks like it was just approved by Apple and is live in the app store! Hope you like it!
KNOWN BUG: Although the app was approved the In App Purchase is still pending approval. There is a bug where if the product does not exist, the app will crash when attempting to bring up the option screen. We have fixed this bug in version 1.0.1 which is pending approval and have resubmitted the in app purchase for approval as well.
