Design-Patterns-In-Swift is a repository that translates classic software engineering design patterns (from sources like the Gang of Four) into Swift code examples, so you can see how those patterns look in a modern, strongly typed, object-/protocol-oriented language. It covers creational, structural, and behavioral patterns: singletons, factories, decorators, observers, strategy, command, mediator, and more.

...The focus of this project is on demonstrating how to structure your code, design your architecture, and the eventual impact of adopting these patterns on testing and maintaining your app. You can use the techniques demonstrated here in many different ways to build apps. Your own particular priorities will impact how you implement the concepts in these projects, so you should not consider these samples to be canonical examples.

...Topics range from language fundamentals (memory management, ARC, value vs. reference types), to UIKit/SwiftUI, concurrency, Grand Central Dispatch, background execution, networking, design patterns, system frameworks, and architecture decisions. Each question is usually backed by sample explanations or code snippets, helping candidates understand not just what to answer but why it matters and how to reason about tradeoffs. Because the repo is maintained, it evolves to reflect changes in the iOS ecosystem: for example, newer Swift concurrency, Combine, SwiftUI, structured concurrency, or recent platform APIs. ...

...Instead of tying state to widget trees, it models state as providers that can be read anywhere, making logic more testable and decoupled from UI. It supports synchronous state, async data (futures/streams) with built-in loading/error handling, and advanced patterns like derived state and provider scopes. Riverpod’s design reduces rebuilds by letting widgets depend on fine-grained slices of state, which leads to predictable performance in complex apps. The ecosystem includes code generation and utilities that help catch invalid provider usage at compile time rather than at runtime. Overall, it encourages a clear separation of concerns and scales cleanly from small prototypes to large, multi-module applications.

Quiver is a comprehensive collection of utility libraries for Dart that extends core functionality and simplifies common programming patterns. It provides reusable tools for asynchronous programming, data structures, caching, time manipulation, string utilities, and more. Originally inspired by Google’s internal libraries, Quiver helps developers write cleaner, more expressive, and testable Dart code. Its modular design allows importing only the needed packages, making it both flexible and lightweight. ...

...Instead of being a simple “how-to” list, it dives into the “why” behind complex behaviors, helping developers reason about Android system design and tradeoffs at a deeper level. This makes the resource suitable for engineers working on performance-critical apps, large codebases, or teams that debug subtle systemic bugs.

AndroidOfferKiller is a curated collection of Android interview resources aimed at helping developers secure stronger job offers. It brings together notes and materials across topics such as Java and JVM basics, Android fundamentals, design patterns, data structures and algorithms, and LeetCode-style problem solutions. The repository also links to deep-dive articles on performance and common pitfalls, for example RecyclerView stutter and optimization strategies, making it a practical study companion rather than just a list of questions. It includes sections about referral channels and hiring information for certain companies, highlighting real-world hiring context in addition to theory. ...

...The repository organizes materials into categories such as video tutorials, books, blogs, and articles, offering a structured path from beginner to advanced topics. It includes both English and Chinese resources, covering Objective-C, Swift, Cocoa frameworks, iOS design patterns, testing, and animation. The project highlights well-known tutorials like Stanford’s iOS development courses, recommended textbooks, and respected blogs from prominent developers in the iOS community. In addition, it provides curated articles that give practical advice on learning strategies, professional development, and best practices for building iOS applications. ...

...You describe your form fields declaratively—types, titles, options, validation hints—and the library generates a UITableView-based UI using appropriate cells and input controls. It supports common patterns like pickers, switches, segmented controls, text fields, and text views, while letting you supply custom cells when your design demands it. The framework handles value binding between the UI and your model object, so you don’t have to wire up outlets or write repetitive save/validate code. Navigation behaviors such as next-field focus and section grouping are built in, improving usability out of the box. ...
