# SwiftUI 26 Features

## Overview

Comprehensive guide to new SwiftUI features in iOS 26, iPadOS 26, macOS Tahoe, watchOS 26, and visionOS 26. From the Liquid Glass design system to rich text editing, these enhancements make SwiftUI more powerful across all Apple platforms.

**Core principle** From low level performance improvements all the way up through the buttons in your user interface, there are some major improvements across the system.

## When to Use This Skill

- Adopting the Liquid Glass design system
