With license and certificates in pocket, Pixelpickle is developing iPhone apps!
Using TestFlight to send builds out to developers and testers of the game. Although currently still stumbling with the device provisioning. They're added in Apple's device managing portal, but not so much in TestFlight. So will keep at that until it's sorted. Working fine on local devices though!
Edit: All sorted with TestFlight now. Builds are being sent to all the right devices.
