ios-accessibility

A guide for adding accessibility support to SwiftUI apps on iOS and macOS, including VoiceOver, text scaling, labels, focus, contrast, and touch targets.

In plain words
What is it for?
Use it when building or reviewing accessible controls, Dynamic Type layouts, VoiceOver labels and actions, focus behavior, hit-testing, and contrast.
Why use it?
It helps prevent interfaces that are difficult to use with screen readers, larger text, touch input, or reduced-motion settings.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ios-accessibility scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

iOS Accessibility

Ship usable apps with VoiceOver, Dynamic Type, and HIG accessibility baselines.

Non-negotiables

ALWAYS NEVER
Meaningful accessibilityLabel on icon-only controls Icon-only buttons with no label
Support Dynamic Type (no fixed tiny text) Rely on color alone for meaning
≥ ~44pt touch targets for interactive controls Trap focus / unreadable contrast
Test with VoiceOver on critical flows Ship decorative noise as accessibility elements

Decision tree

  • Image/button without text? → label + optional hint
  • Group of controls? → combine or container labels
  • Custom control? → traits + value + actions
  • Motion-heavy UI? → respect Reduce Motion

Core patterns

Button {
    isFavorite.toggle()
} label: {
    Image(systemName: isFavorite ? "star.fill" : "star")
}
.accessibilityLabel(isFavorite ? "Remove from favorites" : "Add to favorites")
.accessibilityAddTraits(isFavorite ? .isSelected : [])

Text(title)
    .font(.body) // scales with Dynamic Type
    .accessibilityHeading(.h2)
.accessibilityElement(children: .combine)
.accessibilityAction(named: "Delete") { delete() }

Checklist

  • All interactive elements labeled
  • Decorative images: .accessibilityHidden(true)
  • Dynamic Type: no clipped essential text at largest sizes
  • Contrast sufficient for text/icons
  • VoiceOver order matches visual reading order

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
