Photos
New Features
New keyboard shortcuts are available in Photos on iPadOS, which create quick navigation between Tabs, Search, and Create Albums. While in full-screen mode, you can also delete, duplicate, and enter Edit mode using a keyboard. (57195967)
RealityKit
Known Issues
After updating to iOS & iPadOS 13.4, you won’t be able to synchronize scenes with peers using earlier versions of RealityKit, due to a fundamental change in the physics system. If two peers running a MultipeerConnectivityService have incompatible versions, they will remain connected in the underlying MCSession, but won’t synchronize scenes. iOS & iPadOS 13.4 adds a new NetworkCompatibilityToken class so a host can avoid inviting incompatible clients to its MCSession. Please see the NetworkCompatibilityToken documentation for additional details. (59262764)

New Features
When using a NavigationView with multiple columns, the navigation bar now shows a control to toggle the columns. (49074511)
The
onDragandonDropmodifiers are now available on iOS. (49661347)
Resolved Issues
safeAreaInsets in navigation and tab views now extend to the top edge as expected. If you previously used
edgesIgnoringSafeArea(_:)as a workaround, it should now be removed. (52851281)
