The Touch Controller framework lets you add fully customizable on-screen touch controls to your game that automatically surface as a GCController object, integrating directly with your existing Game Controller input pipeline and rendering via Metal.
• Extends Game Controller framework support to touch input so existing controller-handling code works unchanged — no new game logic required
• Provides nine anchor points, safe-area APIs, and half-screen collider shapes so controls adapt gracefully across every iPhone and iPad screen size
• Controls act as both input and output — icons update contextually, controls hide when irrelevant, and on-screen buttons can replace overlay UIs entirely
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 introduces new SwiftUI drag and drop APIs including reorderable, reorderContainer, dragContainer, and configuration modifiers that enable reordering within and across collections, multi-item drag, and fine-grained control over how data is transferred during drag and drop operations.
PaperKit is Apple's full-featured canvas framework — previously internal-only — now publicly available in iOS/macOS/visionOS 27. It powers the drawing and markup experience in Notes, Preview, and Freeform, giving developers access to a complete pencil, shapes, images, and text canvas with a rich data model.
