Apple is releasing the third beta of iOS 13.4 and iPadOS 13.4 for developers which includes new features including iCloud Drive folder sharing.
Among the most important new features, developers can now sell the macOS and iOS versions of their apps as a single purchase. Apple says this feature will be launched next March when iOS 13.4 is expected to be released publicly.
Apple also releases the third beta for macOS Catalina 10.15.4, watchOS 6.2 and tvOS 13.4 developers
The third beta for developers of macOS Catalina 10.15.4, watchOS 6.2 and tvOS 13.4 is available and also the third public beta version, excluding watchOS 6.2 which is available only for developers.
iOS 13.4 restores the toolbar design for the Mail app introduced in iOS 13 and adds support for iCloud Drive folder sharing, which allows you to share a folder once and allow everyone to see its contents as it changes.
iOS 13.4 also includes a new CarKey function that allows users to lock, unlock and start their car with NFC support without the need for keys, but using the iPhone or Apple Watch.
Other minor changes include new Memoji stickers, new Siri controls, hardware key mapping on iPadOS and more.
