Xcode 18.3 adds design-token importer and Figma artboard synchronization

Design · 5 min read

Apple's Xcode 18.3 includes a new design-token importer that maps color, spacing, typography and elevation tokens into Swift structs and asset catalogs. Teams can now define tokens in JSON or CSS variables and have Xcode generate immutable Swift types that wire directly into SwiftUI's theming APIs, reducing one-off style drift between design and code.

The release also introduces a first-party Figma sync plugin that preserves component structure and constraints when importing artboards into Interface Builder or SwiftUI previews. Rather than flattening layers to bitmaps, the importer translates Figma auto-layout, constraints and variants into adaptable SwiftUI layouts with editable tokens, speeding up developer iteration.

Xcode 18.3 aims to lower friction at the handoff boundary; the tools export change diffs back to Figma so designers can see how components were adapted for platform constraints. Early adopters report fewer reinterpretation rounds and more reliable cross-functional prototypes.
