Apple has moved on to the second generation of its current beta, providing developers iOS 17.3 and iPadOS 17.3 to test out on their iPhones and iPads.

Developers participating in the beta program can pick up the latest builds by visiting the Apple Developer Center or by updating their iPhone or iPad through the Settings app. Public beta versions usually appear shortly after the developer versions, and public participants can sign up through the Apple Beta Software Program website.

The second builds of iOS 17.3 and iPadOS 17.3 follow the first, which Apple issued on December 12.

The new beta's build number for iPhone or iPad is 21D5036c, replacing the first, build number 21D5026f.

So far, the beta for iOS has included Stolen Device Protection, as well as the return of collaborative playlists.

AppleInsider and Apple strongly suggest users don't install test operating systems or other beta or RC 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.
