14 DAY TRIAL // After releasing the first macOS High Sierra 10.13.3 beta the other day, Apple today seeded the first iOS 11.2.5, watchOS 4.2.2, and tvOS 11.2.5 betas to registered developers for testing.
The iOS 11.2.5 beta 1 (15D5037e), tvOS 11.2.5 beta 1 (15K5531d), and watchOS 4.2.2 beta 1 (15S5530d) builds are now available on your Apple Developer account, and you can download and install them on your registered devices through the OTA (Over-the-Air) update system. They include various bug fixes and improvements over previous releases.
In the release notes for iOS 11.2.5, Apple only included information about some known issues related to the ARKit, Xcode, and the Vision framework, along with their workarounds. On the other hand, tvOS 11.2.5 includes the same details about the foundation issue that also affects tvOS 11.2.5 and macOS 10.13.3 beta.
Public betas of iOS 11.2.5 and tvOS 11.2.5 are coming soon
It usually takes Apple about 24 hours to release public beta versions of its iOS, macOS, and tvOS upcoming operating systems once new developer betas are available, so you should expect to be able to install the first iOS 11.2.5, macOS 10.13.3 High Sierra and tvOS 11.2.5 public betas on your registered devices very soon.
