The first developer beta of iOS 12.1 is suitable for developers. AppleInsider takes the leap to discover new features or changes that are in it.
We first performed the first beta through back to back Geekbench tests. The scores were slightly lower than the last tests we performed on the official iOS 12 GM, but this is no cause for concern. As a first beta performance, performance is not critical if changes are made and will likely return to normal levels when we reach the public release. For what it is worth, we have not noticed any real delays in use in the real world.
Especially in this beta we see the return of Group FaceTime. This was removed early in the development cycle of iOS 12 and Apple quickly reduced it.
Apple placed iOS 12.1 beta 1 alongside OS 5.1 and TVOS 12.1, just a day after the public release of iOS 12, OS 5 and TVOS 12.
