After taking some time off for the holidays, Apple has resumed its iOS 12.1.3 beta testing.
Apple today released iOS 12.1.3 beta 3 to registered developers. The update can be downloaded over the air by going to Settings > General > Software Update on your iPhone or iPad, or you can point your computer's web browser to the Apple Developer Center on the web.
As noted by MacRumors, this is actually only the second iOS 12.1.3 beta update released by Apple. It contains the same changes that were included in the first iOS 12.1.2 beta, but Apple released an emergency update to iOS 12.1.2 to avoid a sales ban on iPhones in China due to a legal battle with Qualcomm. The changes that were originally meant for iOS 12.1.2 have been rolled into iOS 12.1.3, and that's how we got to this third beta.
Also released today is the third beta for Apple's watchOS 5.1.3 update. This is likely a minor release that focuses on under-the-hood improvements and fixes.
Apple hasn't said when it'll release iOS 12.1.3 or watchOS 5.1.3 to the public. Stay tuned and we'll let you know when those rollouts commence.
