We are currently hitting an issue where builds from UCB crash on our test devices.
I suspect this is related to the fact that we’re building the game locally using Xcode 8.1, but the newest version on UCB is 8 (trying to prove this claim now).
When is Xcode 8.1 (or newer) going to be available on UCB ?
No immediate plans to add Xcode 8.1 in the short term. I don’t think there are any significant differences that would affect a Unity project building for iOS, but if there is a strong reason to deploy a newer version of Xcode we can make that happen.
