## What it is
A cheat-sheet and Swift Playground demonstrating the SOLID principles of object-oriented design based on Uncle Bob's articles, with runnable Swift 5 examples. It serves as an educational reference for learning OOD principles in Swift.

## Use cases
- learn SOLID principles with Swift examples
- understand single responsibility principle
- see Liskov substitution principle in code
- study dependency inversion in Swift
- teach object-oriented design to iOS developers
- find a quick OOD principles cheat sheet

## When to choose
- you are an iOS or Swift developer learning object-oriented design
- you want runnable playground examples of SOLID principles
- you need a concise reference based on Uncle Bob's articles

## When to avoid
- you need SOLID examples in a language other than Swift
- you want a comprehensive design patterns catalog rather than principles
- you need production-ready code rather than educational snippets

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, documentation
- domain: education, programming-languages, tutorials
- platform: cross-platform
- tags: solid-principles, object-oriented-design, swift-playground, cheat-sheet, computer-science, swift, macos
