Apple releases iOS 13 GM to developers alongside new betas of iOS 13.1, iPadOS 13.1, tvOS 13 and macOS Catalina

Apple has shifted on to another round of developer betas for testing, with updated third builds of iOS 13.1 and iPadOS 13.1 accompanied by the tenth milestone version beta of tvOS 13, and the gold master version of iOS 13.

The latest builds can be downloaded from the Apple Developer Center for participants in the Developer Beta program, as well as via an over-the-air update for hardware already used for beta software. Public beta versions of the developer builds are usually issued within a few days of their counterparts, and can be acquired from the Apple Beta Software Program site.

The third iOS 13.1 build is number 17A5837a, replacing second build 17A5831c. The new iPadOS 13.1 beta is also build 17A5837a, up from 17A5831c for the second build, mirroring the numbers used for iOS. Beta ten of tvOS 13 is 17J5579a, while the ninth was 17J5573a.

Alongside the betas is the Gold Master Seed of iOS 13, with build number 17A577. The Gold Master is effectively the candidate build for public release.

The latest betas and gold master arrive ahead of the public release of the milestone operating system versions. Apple has revealed it will release iOS 13 and iPadOS 13 to the public on Sept. 19, while version 13.1 of each will arrive on Sept. 30.

The betas for iOS 13.1 and iPadOS 13.1 arrive ahead of the release of iOS 13 and iPadOS 13, and largely consist of features that appeared in earlier betas, but are not ready for the primetime milestone release versions for the public. In the first build, Apple brought back the Shortcuts Automation tab, Conversational Shortcuts, the option to share an ETA while in Maps, new HomeKit device icons, accessory animations within HomeKit, dynamic wallpaper updates, new device icons in AirDrop, and a Family Sharing option within Personal Hotspot.

Apple's macOS 10.15 Catalina received an eighth developer build for testing on Tuesday ahead of a launch in October.

Both AppleInsider and Apple strongly suggest users avoid installing betas on to "mission-critical" or primary devices, due to the potential for data loss or other issues. Instead, the recommendation is to install betas onto secondary or non-essential devices, and to ensure there are sufficient backups of important data before making any major changes.
