Figma ↔ SwiftUI

Translation between Figma designs and SwiftUI code, both directions. This file is a router — actual guidance lives in the references below.

Pick the direction

| Direction | Trigger | Reference | |---|---|---| | Design → code | User wants SwiftUI in their iOS project from a Figma file/frame | references/design-to-code.md | | Code → design | User wants to push SwiftUI views / screens / tokens into a Figma file | references/code-to-design.md |

If the request is ambiguous — a Figma URL and .swift files both present, no verb makes it clear — ask the user which direction before loading a reference.

Shared context (applies to both directions)

These points hold regardless of direction; the direction-specific references assume them.

1. get_design_context is the read tool for Figma. Pass clientLanguages: "swift" and clientFrameworks: "swiftui" so the response is framed as Swift. URL → tool args: figma.com/design/:fileKey/:fileName?node-id=:nodeId → use fileKey, replace - with : in nodeId. For figma.com/design/:fileKey/branch/:branchKey/:fileName, use branchKey as fileKey.
2. The React+Tailwind in get_design_context output is a structural reference, not a literal source. It approximates the visual. Never transliterate position: absolute / pixel frames / mix-blend-mode stacks into SwiftUI or into Figma — the screenshot is the source of truth in both directions.
3. iOS HIG semantic colors are tokens, not hex. var(--backgrounds/primary, …), var(--labels/secondary, …), var(--separators/non-opaque, …) etc. map to Color(.systemBackground), Color.secondary, Color(.separator) in SwiftUI, and to variables in a semantic collection in Figma. Keep the mapping; drop the literal RGBA.
4. SF Symbols round-trip by name in both directions — never by codepoint. Design → code: get_design_context substitutes Figma's SF Symbol glyph runs back into <SFSymbol>{Image(systemName: "...")}</SFSymbol> wrappers in the response. Use those names verbatim. Code → design: call figma.util.getSfSymbolCharacter(name) inside use_figma to convert a symbol name to the matching character — never look up codepoints by hand.
5. Recognize the underlying iOS pattern, not the literal node / view name. The same patterns recur in both directions: large title + back chevron + trailing action = NavigationStack chrome; bottom row of icon+label pairs = TabView; repeating same-height rows with leading/trailing chrome = List. Match those system patterns rather than rebuilding them from primitives.
6. For code → design, use_figma is the API. Always load figma-use before any use_figma call. If the task involves building a full screen, also load figma-generate-design; if it involves building components or a design system, also load figma-generate-library.
