Apple has seeded the first official beta of iOS 12.1.3 to both developer and public beta testers. The build, 16D5032a for those keeping score at home, is actually listed as Beta 2 in the release notes from Apple. That is likely because of the whole situation with iOS 12.1.2 earlier this week.
That build was release after the first beta build on Monday, mostly in response to Qualcomm patent claims in China. That build addressed those issues but it is clearly evident now that Apple pushed that release out in a big hurry. With this “first beta” of iOS 12.1.3, things seem to be back in order for the team at Cupertino.
As far as updates or improvements go, this is still in the same vein as the 12.1.2 release. That is, it is a maintenance release. It is focused on bug fixes and other performance improvements, which was the destiny for this “dot” release all along. Don’t expect to see many if any surface changes as most of this will be under-the-hood.
As for when the release will hit the general public, that won’t likely be until mid-January 2019. It is also expect that iOS 12.2 will start its beta cycle in the early part of next year so this .3 release could well be the last we see in the 12.1 train.
If you are a registered developer tester or in the Apple Beta Program, you should have the update ready and available for your devices now. Just head to Settings>General>Software Update on your iPhone to download it and install it.
As always, Average Apple Guy does not recommend installing beta software on your primary iPhone just in case you run into any show stopping bugs.
