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…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
> **Approach: Production-First Iterative Refactoring** — This skill is built for production enterprise codebases where stability and reviewability matter more than speed. Architecture changes are delivered through iterative refactoring — small, focused PRs (≤200 lines, single concern) tracked in a `refactoring/` directory. Critical safety issues ship first; cosmetic improvements come last. # UIKit MVVM Architecture (iOS 13+) 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. ## Architecture Layers ```text View/ViewController → UIViewController + UIView. Binds to ViewModel via Combine/closures/GCD. Renders state. ViewModel Layer → Zero UIKit imports. Exposes ViewState<T>. Uses @Published (Combine) or closures (GCD). …

How to install
mdr add rusel95/ios-agent-skills/uikit-mvvm@sha256:3c213e953b8d68ddThe line at the top of this page pins the label v1.0.4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
