Human Interface Guidelines

Human Interface Guidelines (HIG) is Apple’s comprehensive design framework that defines principles, patterns, and best practices for creating applications across iOS, iPadOS, macOS, watchOS, tvOS, and visionOS. First published in the 1980s for Macintosh and continuously updated to reflect evolving platforms and technologies, HIG provides detailed guidance on interface design, interaction patterns, visual design, typography, color, and platform-specific conventions that help developers create apps that feel native to Apple’s ecosystem.

Mobile developers building for iOS rely on HIG to understand Apple’s design philosophy centered on three fundamental principles: clarity (making content and functionality obvious), deference (letting users interact with content without unnecessary decoration), and depth (using visual layers and realistic motion to convey hierarchy). HIG covers everything from navigation patterns and control specifications to accessibility requirements and app icon design, with platform-specific sections addressing unique capabilities like Face ID, haptic feedback, widgets, and Live Activities. Following HIG is often critical for App Store approval and creating user experiences that feel intuitive to iOS users.

Human Interface Guidelines differ from Material Design in their philosophical approach and platform focus: HIG emphasizes subtlety, translucency, and platform-specific features tailored to Apple’s controlled hardware ecosystem, while Material Design provides more prescriptive component specifications optimized for Android’s diverse devices. HIG is documentation-focused with less emphasis on pre-built component libraries, expecting developers to implement designs using native iOS frameworks like SwiftUI and UIKit.
