Performance and interactivity improvements
The Platforms State of the Union devoted time to SwiftUI, confirming a set of improvements that directly affect rendering speed and container flexibility. According to MacRumors, nested layouts now resize up to twice as fast as in the previous version — a concrete gain for apps with complex view hierarchies. Native drag-to-reorder and swipe actions in any container have also been added, capabilities that previously required custom implementations.
Automatic image caching and finer toolbar control
Two practical utility additions complete the picture: automatic async image caching (no longer requiring manual implementation per app) and finer control over toolbar visibility as space shrinks. These are details that reduce boilerplate code without changing surface-level APIs.
Spatial Preview Framework for visionOS
The most unexpected addition involves visionOS: MacRumors reports that a new Spatial Preview Framework allows developers to stream 3D models from a Mac directly into the physical space of Apple Vision Pro. This makes the development workflow smoother for those building spatial experiences, eliminating the need to transfer and recompile every change on the headset.
