Skill UI

A comprehensive guide for building professional, high-performance native iOS applications. Covers modern frameworks like SwiftUI and Swift 6, alongside deep expertise in UIKit, Core Data, networking (REST/GraphQL), performance profiling, and full App Store lifecycle management. Ideal for developers needing guidance on modern Apple ecosystem best practices.

Comprehensive iOS 26 Liquid Glass design system covering SwiftUI, UIKit, and WidgetKit with interactive blur, tint, and deformation effects for buttons, cards, sheets, and widgets.

A structured playbook for rapidly diagnosing and resolving production incidents related to Lokalise localization services. It guides users through essential quick diagnostics (API health, token validity, rate limits) and provides a decision tree for common failure modes, such as missing or stale translations, API outages, and upload failures, ensuring swift mitigation and postmortem readiness.

This comprehensive workflow guides the process of building and deploying new features that must maintain consistent functionality and design across multiple operating systems (web, mobile, and desktop). It strictly follows an API-first architecture, starting with defining shared API contracts (OpenAPI/GraphQL) and a unified design system. The process then guides parallel implementation across specialized stacks like React/Next.js, SwiftUI, and Jetpack Compose, ensuring high code consistency and faster time-to-market.

Thread-safe data persistence layer that pairs Swift actors with in-memory caching and atomic file storage, eliminating manual synchronization for offline-first apps.

Covers Swift 6.2's proximity concurrency, where code runs on a single thread by default, @concurrent explicitly offloads hotspots, MainActor default inference manages protocol conformance, and compiler settings prevent implicit background execution.

This expert guides you through building modern, high-performance applications across Apple platforms (iOS, macOS, watchOS, tvOS) using Swift 5.9+. It specializes in SwiftUI state management, Protocol-Oriented Architecture, concurrent programming with async/await and Actors, and implementing best practices for type safety and performance optimization. Ideal for developing complex, robust applications.

Guides building testable Swift code by abstracting filesystem, network, and API dependencies into focused protocols, using default production implementations while injecting mocks via Swift Testing for deterministic, actor-safe scenarios.

A comprehensive skill guide for building, reviewing, and optimizing SwiftUI code. It covers modern best practices for state management, optimal view composition, performance optimization, and adopting the latest Apple APIs, including iOS 26+ Liquid Glass features. Use this when ensuring code quality, refactoring complex views, or adhering to strict Apple design guidelines.

Modern SwiftUI patterns for Apple platforms covering @Observable-driven state management, modular view composition, type-safe navigation, performance best practices, environment injection, and preview-driven workflows for high-performance declarative UIs.

This skill guides developers on using the `@expo/ui/swift-ui` package to integrate native SwiftUI views and modifiers into Expo applications. It is essential for building authentic, platform-specific iOS user interfaces within a cross-platform React Native context, especially when targeting Expo SDK 55. Learn how to wrap SwiftUI trees and embed React Native components.

This skill provides a comprehensive framework for designing and reviewing native iOS applications. It covers adherence to Apple's Human Interface Guidelines (HIG), ensuring consistency across layout, typography, safe areas, and system components (e.g., Dynamic Island). Use this when building or reviewing SwiftUI/UIKit code to guarantee the app feels intuitive, highly polished, and genuinely native to the Apple ecosystem.
