+ <objective>

+ Produces iOS and macOS mockups and developer handoff specs: mapping design tokens to the Dynamic Type scale (iOS) or macOS's fixed text-size variants, semantic colors, device/window viewports, Liquid Glass materials, and macOS-specific conventions (system window chrome, desktop tinting, pointer states).

+ The deliverable is a device-framed (iOS) or window-framed (macOS) HTML mockup at exact viewport dimensions plus a SwiftUI-ready handoff spec (named tokens, text styles, semantic colors, sizing, states, spacing). This skill never writes SwiftUI code — implementation is left to `swift-expert` or an Apple-platform developer.

## Design iOS/macOS — Mockup and Handoff, Not Code

### When

After `design-system` tokens exist. This skill never writes SwiftUI — it produces a

static HTML mockup at exact device/window dimensions plus a spec that `swift-expert` or

an Apple-platform developer implements.

### Input

- `design-system.md` — OKLCH palette, typography direction, motion personality.

- The screen/flow to mock up and the target platform: iPhone / iPad (iOS) or a resizable

window (macOS).

### Steps — iOS

1. **Map tokens to iOS roles.** Typography → Dynamic Type text styles, anchored at Body

17pt down to Caption 2 11pt (never fixed point sizes) — see `references/dynamic-type.md`.

Colors → semantic color roles (never raw RGB/hex) — see `references/semantic-colors.md`.

2. **Pick the device viewport(s)** from `references/viewports.md` — mock up in exact

points at the chosen scale factor.

3. **Build the HTML mockup**: a device-frame `<div>` at the exact viewport dimensions,

`viewport-fit=cover` meta tag, `env(safe-area-inset-*)` for notch/Dynamic Island/home

indicator spacing. See `references/mockup.md`.

4. **Apply Liquid Glass where it fits** — a floating layer of controls *above* regular

content, not a content background. Two variants: **regular** (content-aware, the

default for controls) and **clear** (more transparent — dim the content beneath it

~35% when clear sits over light content, so controls stay legible). Plus control

morphing, concentricity between nested shapes, layered icon treatment. Source:

developer.apple.com/design/human-interface-guidelines/materials (Liquid Glass, iOS 26).

See `references/liquid-glass.md` — do not invent numeric corner-radius values; none are

published.

5. **Verify touch targets and contrast**: 44×44pt minimum touch target (see

`references/touch-targets.md`); **4.5:1 minimum contrast in Dark Mode** for body text

(WCAG AA, HIG-endorsed) — check both light and dark against

`references/semantic-colors.md` roles, not a single-mode check.

6. **Sidebar navigation ≤ 2 levels deep.** If the flow needs a 3rd level, restructure

(tabs, push navigation, or a secondary sidebar) rather than nesting a 3rd disclosure

tier — deeper sidebars are a documented HIG anti-pattern for iPadOS/macOS sidebars.

Source: developer.apple.com/design/human-interface-guidelines/layout.

7. **Write the handoff spec** per `references/handoff-swiftui.md`: named tokens only

(never raw values), Dynamic Type text styles (never fixed sizes), semantic colors,

explicit sizing behavior (fixed/hug/fill) per element, all interaction states

(disabled/pressed/focused), spacing in pt.

### Steps — macOS

1. **Map tokens to macOS text sizes.** macOS uses its own fixed scale, distinct from iOS

Dynamic Type — confirmed anchors: **Large Title 26pt** down to **body ~13pt**, floor

**Caption 2 ~10pt**. Source: developer.apple.com/design/human-interface-guidelines/typography.

**Gap — do not invent**: the full intermediate scale (Title 1–3, Headline, Subhead,

Footnote point values) is not confirmed in this pass; reconfirm on the HIG typography

page or Xcode's SF font catalog before using an intermediate size verbatim.

2. **No Dynamic Type on macOS** — the platform ships fixed size *variants per context*

(e.g. control sizes: regular/small/mini) instead of a user-adjustable type scale. Pick

the variant that matches the control's context, don't apply an iOS Dynamic Type style.

3. **Never draw a custom window chrome.** Title bar, traffic lights, toolbar, and sidebar

are system-drawn; the mockup should frame content inside a standard macOS window shape,

not invent custom chrome. Source: developer.apple.com/design/human-interface-guidelines/windows.

4. **Desktop tinting**: background materials pick up a subtle tint from the desktop

picture/wallpaper behind the window — reflect this as a soft, low-opacity tint layer in

the mockup, not a flat opaque background. Source:

developer.apple.com/design/human-interface-guidelines/materials.

5. **Pointer feedback, not touch feedback**: hover, highlight, and lift states on

interactive elements (buttons, list rows) — macOS is pointer-driven, so every hoverable

control needs a hover state in the mockup and handoff spec, unlike iOS/iPadOS touch-only

flows. Source: developer.apple.com/design/human-interface-guidelines/pointing-devices.

6. **Window sizing is a mockup convenience, not a spec.** Unlike iOS device viewports,

macOS windows are user-resizable — pick a reasonable default canvas (e.g. common

productivity-app widths) for the mockup, but do not present it as an official fixed

dimension; state that explicitly in the handoff spec.

7. **Write the handoff spec** per `references/handoff-swiftui.md`, adapted: macOS text

sizes instead of Dynamic Type styles, hover/pressed/focused states (pointer, not touch),

otherwise same named-token discipline.

### Failure Handling

- Screenshot/preview tooling unavailable → describe the mockup in the handoff spec with

exact pt values instead of blocking on a visual.

- A fact needed isn't in the references below → mark it "to reconfirm on

developer.apple.com" in the output; never invent a number. This applies in particular to

**iOS/macOS spacing and corner-radius grids — neither is published as an official numeric

scale**; do not invent an 8pt-style grid for Apple platforms, point instead to Xcode's

Design Resources / SF Symbols catalog as the source of truth to reconfirm against.

### Output

- Device-framed (iOS) or window-framed (macOS) HTML mockup at exact viewport

points/reasonable default canvas.

- `handoff.md` (or equivalent) with named tokens, text styles, semantic colors, sizing,

states, spacing — ready for `swift-expert`.

### Next → `design-review` (mockup-scoped: screenshot the mockup, verify contrast, no

full site audit loop).
