Apple has released the second developer betas of iOS 15, iPadOS 15, tvOS 15, and watchOS 8. Registered developers can download the betas via Apple’s developer portal.
Or they can be downloaded over-the-air once the proper configuration profile has been installed from the Developer Center. Speaking of the operating systems, Apple will almost certainly preview iOS 15, iPadOS 15, macOS 12, tvOS 15, and watchOS 8 at next week’s Worldwide Developer Conference.
