How does it handle the transition to the @Observable macro?

It actively promotes @Observable over the legacy ObservableObject for new code and provides clear rules for when to use @State vs @Bindable in the modern paradigm.

Does it enforce a specific architecture like MVVM or TCA?

No, this skill focuses on SwiftUI-native facts and best practices for state and view management without enforcing a specific external architectural pattern.

Can it assist with iOS 26+ Liquid Glass effects?

Yes, it contains specific patterns for GlassEffectContainer and interactive glass styles, specifically for developers targeting the latest Apple design languages.

Does it help with SwiftUI performance issues?

Absolutely. It includes specific patterns for minimizing redundant state updates, using lazy stacks, and ensuring stable identity in lists to prevent layout thrash.

Does this skill support older iOS versions?

Yes, while it prioritizes modern APIs, it includes guidelines to provide sensible fallbacks for features like Liquid Glass using #available checks.

Mobile Development

Builds and refactors modern SwiftUI applications with advanced state management, performance optimizations, and iOS 26+ Liquid Glass adoption.

The SwiftUI Expert Skill provides deep domain-specific guidance for developers building iOS and Apple platform applications. It streamlines the implementation of complex features by enforcing best practices for state management (favoring the @Observable macro), performance-conscious view composition, and the adoption of modern APIs like NavigationStack. Whether you are refactoring legacy ObservableObject patterns, optimizing list performance, or experimenting with futuristic Liquid Glass interfaces for iOS 26+, this skill ensures your code is idiomatic, high-performance, and aligned with Apple's latest design guidelines.

Key Features

01Performance Optimization: Strategies for minimizing view updates, image downsampling, and efficient list rendering.

02Modern State Management: Expert guidance on @Observable, @State, and @Bindable property wrappers.

033 GitHub stars

04API Modernization: Automatically identifies and replaces deprecated modifiers like cornerRadius and navigationView.

05iOS 26+ Liquid Glass: Implementation patterns for futuristic glass effects with reliable legacy fallbacks.

06View Composition: Enforces clean extraction of subviews and maintains view identity for smooth transitions.

Use Cases

01Refactoring legacy SwiftUI codebases to use the modern Swift 5.9+ @Observable macro system.

02Optimizing high-frequency UI updates and list performance in complex iOS applications.

03Implementing type-safe navigation and modern tab structures using the latest Apple platform APIs.
