Uikit Mvvm

Category: Engineering  ·  Sub-category: testing  ·  Last updated:
Use for hands-on UIKit MVVM questions: setting up Combine bindings between UIViewController and ViewModel (@Published + sink), extracting business logic from massive ViewControllers step by step, testing ViewModels with XCTestExpectation + Combine publishers, fixing [weak self] retain cycles in sink closures, migrating DispatchQueue/GCD completion handlers to Combine, or replacing reloadData() with DiffableDataSource. Also covers Coordinator navigation patterns, constructor injection, ViewState enum, and incremental MVC-to-MVVM refactoring. Trigger on any UIKit architecture decision — even when the user doesn't mention 'MVVM' explicitly.

From the source SKILL.md

Enterprise-grade UIKit MVVM architecture skill. Opinionated: prescribes Combine-bound ViewModels, Coordinator navigation, constructor injection via factories, ViewState enum, DiffableDataSource, and programmatic Auto Layout. Adopts a production-first iterative refactoring approach — every pattern is chosen for testability, reviewability, and safe incremental adoption in large teams. UIKit MVVM remains the dominant production architecture for large-scale iOS apps.

What this skill does

Uikit Mvvm is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/uikit-mvvm/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Uikit Mvvm Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 158,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
