Audit UIKit-based screens for accessibility issues with concrete VoiceOver and Dynamic Type fixes
Build production UI that reads as a deliberate choice for this project rather than an LLM default, and audit shipped UI for the tells that give it away. Use when the user says "build this page", "make this UI not look AI-generated", "this looks like slop", "design this screen", "audit our UI", "make the frontend look good", or "/uikit". Reads a project's DESIGN.md when one exists; never writes it.
Write, review, or improve UIKit code following best practices for view controller lifecycle, Auto Layout, collection views, navigation, animation, memory management, and modern iOS 18–26 APIs. Use when building new UIKit features, refactoring existing views or view controllers, reviewing code quality, adopting modern UIKit patterns (diffable data sources, compositional layout, cell configuration), or bridging UIKit with SwiftUI. Does not cover SwiftUI-only code.
Comprehensively reviews UIKit code for best practices on modern APIs, architecture, and performance. Use when reading, writing, or reviewing UIKit-based iOS projects, including UIViewController, UITableView, UICollectionView, Auto Layout, or programmatic UI code. Also use when migrating legacy UIKit patterns to modern equivalents. Do not use for SwiftUI-only projects or Combine-only logic with no UIKit dependency.
Bridge UIKit and SwiftUI — wrap UIKit views/view controllers in SwiftUI using UIViewRepresentable/UIViewControllerRepresentable, embed SwiftUI in UIKit with UIHostingController, and handle the Coordinator delegate pattern. Use when integrating camera previews, map views, web views, mail compose, document scanners, PDF renderers, text views with attributed text, or any third-party UIKit SDK into a SwiftUI app. Also use when migrating a UIKit app to SwiftUI incrementally, or when needing UIKit features not yet available in native SwiftUI.
Use when wrapping UIKit views/controllers in SwiftUI, embedding SwiftUI in UIKit, or debugging UIKit-SwiftUI interop issues. Covers UIViewRepresentable, UIViewControllerRepresentable, UIHostingController, UIHostingConfiguration, coordinators, lifecycle, state binding, memory management.
Use when bridging UIKit and SwiftUI, debugging Auto Layout constraints, working with Combine, TextKit, or UIKit animations.
Use when building iOS apps with UIKit, implementing MVVM/MVC/Coordinator patterns, or integrating UIKit with SwiftUI.
Master UIKit for iOS app development - views, view controllers, Auto Layout, table/collection views
Use when building UIKit interfaces without storyboards, setting up Auto Layout constraints with anchors, creating reusable UI components, or encountering layout constraint errors and ambiguous layout warnings
Use when CAAnimation completion handler doesn't fire, spring physics look wrong on device, animation duration mismatches actual time, gesture + animation interaction causes jank, or timing differs between simulator and real hardware - systematic CAAnimation diagnosis with CATransaction patterns, frame rate awareness, and device-specific behavior
API reference: UIKit. Query for UIView, UIViewController, controls, table and collection views, navigation controllers, scenes, Auto Layout, images, colors, gestures, presentation, and SwiftUI hosting.
