...Like other Rx implementation, RxSwift's intention is to enable easy composition of asynchronous operations and streams of data in the form of Observable objects and a suite of methods to transform and compose these pieces of asynchronous work. KVO observation, async operations, UI Events and other streams of data are all unified under abstraction of sequence. This is the reason why Rx is so simple, elegant and powerful.

...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. Many interviewers and candidates use it as a structured prep tool: reviewing categories, doing mock answers, or drilling tricky concepts.

Tame async code with battle-tested promises. Because async code is hard to write, hard to read, hard to reason about. A pain to maintain. By using a then keyword that enables you to write aSync code that reads like an English sentence. Async code is now concise, flexible and maintainable.

...Xcode 11 introduced Previews which is a fantastic way to quickly validate your UI in multiple scenarios just like Sizes did. If you'd like to know more about Xcode Previews I recommend this WWDC session. You can even use Previews with UIKit so there's no reason to stick to this library.

Katana is a modern Swift framework for writing iOS applications' business logic that are testable and easy to reason about. Katana is strongly inspired by Redux. In a few words, the app state is entirely described by a single serializable data structure, and the only way to change the state is to dispatch a StateUpdater. A StateUpdater is an intent to transform the state, and contains all the information to do so. Because all the changes are centralized and are happening in a strict order, there are no subtle race conditions to watch out for. ...
