tvOS 27 introduces system-wide Dynamic Type support, allowing users to choose preferred text sizes (Large through Accessibility XXXL) in Settings. Apps built with standard UIKit and SwiftUI text styles adapt automatically, while custom layouts can respond via the dynamicTypeSize environment value.
• Millions of Apple TV users who rely on larger text sizes can now benefit from accessible apps — and the App Store Accessibility Nutrition Label lets developers signal this support to reach them
• Standard UIKit/SwiftUI components (Label, Button, NavigationBar) scale automatically; developers only need to audit custom views for hard-coded fonts and fixed constraints
• Conditional layouts using AnyLayout or UIStackView axis switching let you maintain a great visual design at default sizes while gracefully adapting for accessibility sizes
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.
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.
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.
