Following the release of the first iOS 9.3.2 build, Apple has seeded developers with the first beta of watchOS 2.2.1. The build carries the number of 13V413 and can be downloaded via the Apple developer center.
This beta will probably include just bug fixes opposed to user facing changes, as dot-dot updates normally tend to focus on repairs. However, it looks like this build is specific more to developers as in the release notes, Apple mentions issues and workarounds for watchOS 1 WatchKit apps as well as Xcode crashes. But other than that, there’s not much different between watchOS 2.2.1 and 2.2.
We’ll update this post if anything new is discovered in the latest beta!
