Apple publishes iOS/iPadOS 15.2 beta 4, watchOS 8.3 beta 4 and tvOS 15.2 beta 4. Unfortunately, no new Xcode betas are released.
No notable changes are reported for this set of beta versions.
iOS and iPadOS 15.2 add support for App Privacy Report, a feature that Apple first highlighted back at WWDC. With App Privacy Report, you can see how often apps are accessing sensitive info granted to them through privacy permissions, such as location, camera, microphone, and contacts.MacRumors
