Apple has issued new builds of iOS 12.1 beta to support the latest iPhone XS and XS Max that includes the delayed group FaceTime Feature.
The first beta of iOS was released earlier this week for existing iPhones, but now that iPhone XS and XS Max are available to customers, additional builds have been released.
This comes at the perfect time for customers eagerly receiving new iPhones today, as it is impossible to restore a new phone from a backup of newer version of iOS. A user’s current iPhone was running iOS 12.1 beta, there is no better way to restore from a backup of that device, running that version of the operating system until the new iPhone XS or iPhone XS Max is updated to the Beta as well.
The iOS beta 12.1 seems to be a minor update this far, mostly just including support for Group FaceTime. Other Minor Changes were found in the code like destined for the new iPads landing this fall.
