iOS 26/27 introduces Liquid Glass, a new design language that separates apps into a UI layer (navigation, tab bars, toolbars) and a content layer (scroll views, imagery, color). This architecture lets brand color and content breathe edge-to-edge while native controls float above and dynamically pick up brand colors.
• Moving brand color into the scroll view content area (rather than solid toolbar backgrounds) lets Liquid Glass controls dynamically reflect your palette while keeping native familiarity
• Custom components still work but should be reserved for high-impact, brand-defining moments — standard components like context menus, sheets with concentric edges, and SwiftUI Zoom Transitions are now more expressive than ever
• Supporting Dark Mode, Dynamic Type with custom fonts, and accent/tint color intentionally are now table-stakes for brand integrity on iOS 27
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.
