Apple HIG: Selection and Input Controls

Check for .claude/apple-design-context.md before asking questions. Use existing context and only ask for information not already covered.

Key Principles

  1. Clear current state. Users must always see what is selected. Toggles show on/off, segmented controls highlight the active segment, pickers display the current selection.

  2. Prefer standard system controls. Built-in controls provide consistency and accessibility. Custom controls introduce a learning curve and may break assistive features.

  3. Toggles for binary states. On or off. In Settings-style screens, changes take effect immediately. In modal forms, changes commit on confirmation.

  4. Segmented controls for mutually exclusive options. 2-5 items, roughly equal importance, short labels.

  5. Sliders for continuous values. When precise numeric input is not critical. Provide min/max labels or icons for range endpoints.

  6. Pickers for long option lists. Too many options for a segmented control. Works well for dates, times, structured data.

  7. Steppers for small, precise adjustments. Increment/decrement in fixed steps. Display current value next to the stepper with reasonable min/max bounds.

  8. Text fields for short, single-line input. Text views for multi-line. Configure keyboard type to match expected input (email, URL, number).

  9. Combo boxes: text input + selection list. macOS. Type a value or choose from a predefined list when custom values are valid.

  10. Token fields: discrete values as visual tokens. macOS. For email recipients, tags, or collections of discrete items.

  11. Gauges and rating indicators display values. Gauges show a value within a range. Rating indicators show ratings (often stars). Display-only; use interactive variants for input.

Output Format

  1. Control recommendation with rationale and why alternatives are less suitable.
  2. State management -- how the control communicates current state and whether changes apply immediately or on confirmation.
  3. Validation approach -- when to show errors and how to communicate rules.
  4. Accessibility -- labels, traits, hints for VoiceOver.

Questions to Ask

  1. What type of data? (Boolean, choice from fixed set, numeric, free-form text?)
  2. How many options?
  3. Which platforms? (Combo boxes and token fields are macOS-only)
  4. Settings screen or inline form?
