Along with iOS 12.1 developer beta 1, Apple has also seeded beta 1 of watchOS 5.1 to registered developers and beta testers.
The registered developer can install the latest beta by going to Apple’s Developer Center page and installing the necessary configuration profile. Once the configuration is set, a developer can download the newest beta from the Apple Watch iOS app on iPhone.
Remember that the Apple Watch must be connected to the charger and have at least 50% of the battery life before you could install watchOS 5.1 beta 1 on your Apple Watch.
We have not found any significant changes and updates in this new beta, If found, we will update in next post.
