FAQPage Schema
How do I choose the right color for UI elements in iOS following Apple's design guidelines?

Apple HIG recommends using semantic colors—primary, secondary, tertiary, and background colors—that adapt automatically to light and dark modes. This Skill resolves which semantic color fits your specific UI element, ensuring consistency across iOS, iPadOS, macOS, watchOS, tvOS, and visionOS.

What's the best way to defend my design decisions to stakeholders using Apple HIG?

This Skill provides quick-lookup references and decision frameworks tied directly to Apple HIG guidance. Use it to find the specific HIG principle supporting your choice—whether for typography, color, spacing, or accessibility—so you can cite authoritative guidelines when justifying design decisions.

How do I ensure my app's typography meets Apple HIG standards?

Apple HIG defines specific font weights, sizes, and line heights for different text roles. This Skill delivers cross-platform typography decisions, helping you select the right weight and scale for body text, headlines, and captions that work consistently across all Apple platforms.

Can I use this for accessibility compliance when designing iOS interfaces?

Yes. This Skill covers accessibility decisions including color contrast, text sizing, and interactive element affordances across iOS, iPadOS, macOS, watchOS, tvOS, and visionOS. It connects to accessibility-diag for deeper validation when you need detailed compliance checks.

What should I do when my design choice doesn't clearly map to a single HIG pattern?

This Skill resolves UI design ambiguities through decision trees and checklists that clarify which HIG principle applies. When multiple patterns could fit, it helps you evaluate trade-offs and select the most appropriate option for your context and platform.

Does this cover dark mode implementation across all Apple platforms?

Yes. This Skill provides color, background, and contrast decisions for dark mode across iOS, iPadOS, macOS, watchOS, tvOS, and visionOS, ensuring your UI remains readable and visually coherent in both light and dark appearances.
