visionOS 27 introduces ClippingComponent and enhanced ManipulationComponent placement patterns in RealityKit, enabling multiple users in a SharePlay session to simultaneously manipulate, disassemble, and cross-section structured 3D assemblies in shared space.
ā¢ ClippingComponent is new in visionOS 27, letting you define an axis-aligned bounding box that discards geometry outside its bounds at render time ā making complex interiors accessible without destroying the mesh
ā¢ Placing ManipulationComponent at different levels of an entity hierarchy dynamically switches an assembly between "single manipulable object" and "individually grabbable parts" with no geometry changes
ā¢ Combining SharePlay with structured RealityKit hierarchies enables true multi-user spatial collaboration on CAD, architecture, logistics, and any multidimensional dataset
Liquid Glass is Apple's new material and visual design language introduced in iOS 27, bringing translucent, refractive glass-like surfaces to system and custom UI elements. It replaces the frosted vibrancy aesthetic with a more dynamic, depth-aware material that responds to content beneath it.
iOS 27 brings a sweeping set of SwiftUI enhancements including Liquid Glass design adoption, new toolbar visibility and overflow APIs, document architecture improvements with Observable, and resizable iPhone app support ā all designed to modernize app UIs with minimal code changes.
Xcode 27 introduces a fully customizable toolbar and theme system, untitled scratch projects, coding agent integration directly in the editor, and the new Device Hub for evaluating apps across simulators and physical devices side-by-side.
