The Gamery 1.7 iCloud sync beta has expanded to 40 more users. Go here: https://testflight.apple.com/join/yIVv4hX2
A first TestFlight beta is going out in a few minutes to anyone who dropped me an email!
Getting CloudKit sync to work is a lot of work and testing. Here's my little test app that I use to verify everything works as expected. Everything looks fine for now, but I always say that until I find the next ugly bug the next day. Hopefully I can try integrating this into Gamery later this week.
Your Game Library Has Never Looked More Beautiful.
