Apple releases beta 4 for iOS/iPadOS 16, macOS 13 Ventura, watchOS 9 and tvOS 16. Most notable addition is support for Live Activities.
Live Activities and ActivityKit won't be included in the initial publicly released version of iOS 16, but will be publicly available in an update later this year. Once they're publicly available, you can submit your apps with Live Activities to the App Store.
