Apple distributes second watchOS 10.3 developer beta

Developers can download the new watchOS beta

Developers taking part in the beta program can acquire the latest versions via the Apple Developer Center or by updating their devices with the beta software. Public beta versions are typically available a short time after the developer releases, via the Apple Beta Software Program.

The second developer beta for watchOS 10.3 arrives after the first, which was seeded on December 12.

The second build of watchOS 10.3 is number 21S5635d, replacing the first, 21S5625c.

So far, it doesn't seem like there are any major new features in watchOS 10.3, so it may end up being a bug fix and performance improvement fix release.

AppleInsider and Apple strongly suggest users don't install beta operating systems or other beta software on "mission-critical" or primary devices, as there is the small chance of issues that could result in the loss of data. Testers should instead use secondary or non-essential hardware and ensure they have sufficient backups of their critical data at all times.
