module UI::DesignTokens::AppleGenerator

Overview

Emits a Swift file from a UI::DesignTokens::Tokens instance.

Output is consumed by Phase 3 (SwiftUI bridge). Deterministic: same input bytes → same output bytes.

Mapping rules (per implementation.md §4.2):

• Spacing / radius rem are multiplied by 16 to convert to Apple points.
• Type sizes track the brand's value verbatim; the brief's "HIG default 17pt body" override applies only when the brand has explicitly not set a size. We hold the brand's value through faithfully — the default Tokens already encodes the body at 1.0rem (16pt) which is the standard cross-platform body, and a downstream SwiftUI consumer can substitute SF Dynamic Type if they want HIG-canonical 17pt.
• Font.Weight mapping is documented inline.
• ease_standard → UnitCurve.easeInOut, ease_emphasized round-trips the bezier 4-tuple. spring is dropped — SwiftUI manages its own spring curves via .spring().
