# uikit-max Reviews UIKit code against 12 architectural domains across iOS 13 through iOS 26. Spots deprecated APIs, layout issues, and thread safety bugs. - plugin · `type=plugin` · Claude Code · ★ 49 - Author: tornikegomareli - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/tornikegomareli/UIKit-Agent-Skill - Updated: 2026-07-05 - HTML: https://affpapa.org/en/nevibecode/plugins/uikit-max ## What it does The plugin runs a 12-step review of UIKit components. It checks Auto Layout anchors and view controller lifecycle methods alongside Swift Concurrency rules. The rule set covers legacy patterns like UIAlertView as well as iOS 26 additions, including `updateProperties()`, Liquid Glass effects, and typed notifications. Reference guides load dynamically. The skill pulls only the documentation needed for the specific task at hand. Each guideline includes explicit iOS version availability tags, providing tested fallback patterns whenever a project targets older system releases. ## Install ### Claude Code (native platform) **Plugin marketplace** In the agent chat (not a shell): ```text /plugin marketplace add anthropics/claude-plugins-community ``` In the agent chat (not a shell): ```text /plugin install uikit-max@claude-community ``` ## When to use it - Replace deprecated UIKit classes like UIWebView with modern alternatives - Audit Auto Layout constraints and Safe Area margins - Verify VoiceOver traits, dynamic font scaling, and 44pt touch targets - Identify main thread blocking calls and retain cycles in view controllers ## Example prompts - /uikit-max - /uikit-max Focus on accessibility - Use UIKit Max to review my view controller for memory leaks ## Source text · SKILL.md · MIT Below is the content of a third-party file.

It covers the full surface of UIKit development from iOS 13 through iOS 26 — deprecated API replacement, the complete iOS 26 UIKit overhaul (Liquid Glass, updateProperties(), automatic Observable tracking, UICornerConfiguration, HDR colors, typed notifications, interruptible transitions, UIGlassEffect, UIScrollEdgeEffect, iPad menu bar, UISplitViewController inspectors), Auto Layout best practices, view controller lifecycle and architecture, diffable data sources and compositional layout, accessibility compliance, concurrency and thread safety, the #Preview macro, @Observable adoption patterns, and Objective-C interop. Every rule is annotated with its iOS version availability and includes fallback guidance for projects targeting older versions. Built on the [Agent Skills](https://agentskills.io) open standard. Works with Claude Code, Codex, Gemini, Cursor, and any agent that supports the specification. ## What the Skill Covers The skill performs a 12-step review of UIKit code, loading only the reference files relevant to the task: | Domain | Key Topics | |--------|------------| | Deprecated API | UIAlertView, UIWebView, legacy cell properties, UIButton.Configuration, UIScene lifecycle mandatory migration, .done to .prominent, .inline to .integrated, all iOS 26 Liquid Glass button/glass/corner/HDR/notification APIs with fallbacks for iOS 13-25 | | Views | UIView lifecycle including updateProperties() (iOS 26), composition vs inheritance, draw(_:) vs CALayer, UICornerConfiguration, .flushUpdates animation, automatic @Observable tracking in layoutSubviews/updateProperties/updateConstraints/draw with back-deployment to iOS 18, conditional observation gotchas, retain cycle risks | | Auto Layout | Anchor API over NSLayoutConstraint(item:), NSLayoutConstraint.activate batching, UIStackView, content hugging/compression resistance, Safe Area, layout margins, scroll view contentLayoutGuide/frameLayoutGuide, NSDirectionalEdgeInsets for RTL | | View Controllers | Full lifecycle order with viewIsAppearing (iOS 13+ back-deployed) and updateProperties (iOS 26+), separate view update cycle (Traits/updateProperties/layoutSubviews/Display), Massive VC avoidance, child containment API, coordinator pattern, UISplitViewController inspectors, UIHostingSceneDelegate, iPad menu bar with UIMainMenuSystem, Observable auto-tracking in 7+ VC methods | | Navigation | Coordinator pattern, UISheetPresentationController detents (iOS 15+) with custom detents (iOS 16+), deep linking, UINavigationBarAppearance, iOS 26 subtitles/largeTitle/identifier/interruptible transitions/sharesBackground/tab bar minimize/UITabAccessory | | Table/Collection Views | Diffable data sources (iOS 13+), compositional layout (iOS 13+), CellRegistration (iOS 14+), UIContentConfiguration (iOS 14+), UIHostingConfiguration for SwiftUI-in-cells (iOS 16+), configurationUpdateHandler (iOS 15+), reconfigureItems (iOS 15+), prefetching, Observable auto-tracking in cell providers (iOS 26+) | | Accessibility | VoiceOver labels/traits/hints/values, Dynamic Type with UIFontMetrics and @ScaledMetric (iOS 14+), 44pt touch targets, Reduce Motion, color differentiation, accessibility notifications, grouped elements | ``` END THIRD-PARTY FILE 81766159b2d238d6 The third-party file has ended.
