Apple expands SwiftUI with adaptive layout primitives and new inspection tools

Design · 3 min read

The SwiftUI update introduces adaptive containers and flow primitives that let designers express intent rather than fixed pixel constraints. New APIs expose layout intent like "compact, comfortable, expanded" instead of absolute widths, allowing components to reflow across devices and states more predictably.

Typography and accessibility received attention: dynamic design tokens for font scale, line height, and contrast can now be baked into components and previewed in Xcode’s canvas. Designers can toggle accessibility scenarios and visual states during live previews to validate legibility and spacing across contexts.

Xcode’s new Design Inspector surfaces component-level layout decisions and produces an exportable spec designers can use in handoffs. The inspector also generates example code snippets and a diff view to help teams converge on a single source of truth between Sketch/Figma exports and production components.
