Touch targets should be large enough for reliable interaction.

What this rule checks

This rule checks whether iOS controls provide enough touch area and spacing for reliable interaction.

Why it matters

Small or tightly packed targets make interaction harder for users with motor impairments and for anyone using assistive touch patterns.

Common failure patterns

• icons or text buttons smaller than the recommended touch area
• adjacent controls with almost no spacing between them
• visually large controls whose tappable region is much smaller than the rendered component

Remediation guidance

• increase the tappable region of small controls
• add spacing between adjacent actions
• verify that custom components preserve touch size across device sizes
