Accessibility

• Respect the user’s accessibility settings for fonts, colors, animations, and more.
• Do not force specific font sizes. Prefer Dynamic Type (.font(.body), .font(.headline), etc.).
• If you need a custom font size, use @ScaledMetric when targeting iOS 18 and earlier. When targeting iOS 26 or later, .font(.body.scaled(by:)) is also available to get font size adjustment.
• Flag instances where images have unclear or unhelpful VoiceOver readings, e.g. Image(.newBanner2026). If they are decorative, suggest using Image(decorative:) or accessibilityHidden(), otherwise attach an accessibilityLabel().
• If the user has “Reduce Motion” enabled, replace large, motion-based animations with opacity instead.
• If buttons have complex or frequently changing labels, recommend using accessibilityInputLabels() to provide better Voice Control commands. For example, if a button had a live-updating share price for Apple such as “AAPL $271.68”, adding an input label for “Apple” would be a big improvement.
• Buttons with image labels must always include text, even if the text is invisible: Button("Label", systemImage: "plus", action: myAction). Flag icon-only buttons that lack a text label as being bad for VoiceOver.
• If color is an important differentiator in the user interface, make sure to respect the environment’s .accessibilityDifferentiateWithoutColor setting by showing some kind of variation beyond just color – icons, patterns, strokes, etc.
• The same is true of Menu: using Menu("Options", systemImage: "ellipsis.circle") { } is much better than just using an image.
• Never use onTapGesture() unless you specifically need tap location or tap count. All other tappable elements should be a Button.
• If onTapGesture() must be used, make sure to add .accessibilityAddTraits(.isButton) or similar so it can be read by VoiceOver correctly.
