Today, Apple has seen fit to release a new beta build of its upcoming iOS 12.1.3 update to developers. The update arrives only a few days after the company rolled out iOS 12.1.2 to the general public which brought the eSIM feature and several changes related to the ongoing legal battle with Qualcomm in China. Other than iOS 12.1.3, Apple has also seeded the second developer beta of macOS 10.14.3 and tvOS 12.1.2. Let’s dive in to see some more details on the changes brought forward in the latest beta builds.

If you’re interested, you can download the new beta right now. If you’re a registered developer, you can download iOS 12.1.3 beta from the Apple Developer Center or via the over-the-air mechanism. However, do make sure that an appropriate profile is installed from the Developer Center.
