Xcode adds AI-assisted SwiftUI code completions and Interface Designer suggestions

Design · 4 min read

Xcode's latest release expands its code-completion system with a SwiftUI-focused AI assistant that suggests view hierarchies, modifiers and accessibility annotations in context. The assistant recommends both high-level layouts and small refinements — for example, proposing suitable alignment and spacing modifiers based on surrounding code and declared design tokens.

Interface Designer has also gained AI-driven layout suggestions: when a developer drops a component onto a canvas, Xcode proposes adaptive constraints and typographic scales consistent with platform guidelines. It can also generate localized variants and accessibility labels, speeding up the handoff from design to implementation.

Apple says all AI inference runs on-device by default using the new CoreMLRunner optimizations, and developers are given clear toggles in preferences to enable or disable telemetry used to improve models. The release notes stress sample-based transparency: generated snippets include comments describing the reasoning behind certain suggestions so teams can review and audit changes.
