Swift Argument Parser is a type-safe, declarative library for building Swift command-line tools by annotating your command types with property wrappers like @Option, @Argument, and @Flag. It handles parsing, validation, automatic help generation, and dispatch to your run() or async entry point, letting you focus on command logic instead of boilerplate. The package supports subcommands, default values, custom parsing strategies, and rich error messages that match platform conventions. It integrates cleanly with Swift Package Manager, works well in CI, and provides incremental improvements such as Sendable conformances for wrappers to help in concurrent contexts. ...

This repository collects a broad, categorized list of interview questions (with expected answers) that are commonly asked in iOS or Swift engineering interviews. 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. ...

Sugar is a sweetener for your Cocoa implementations. Gain easy access to main bundle information. To easily exclude operations from when you as a developer runs the application in the simulator, not subscribing to push notification or running analytics operations etc. Observe the keyboard showing and hiding events, and handle it.

Async is a syntactic sugar in Swift for asynchronous dispatches in Grand Central Dispatch. Now more than syntactic sugar for asynchronous dispatches in Grand Central Dispatch (GCD) in Swift. Custom queues, dispatch block after delay, cancel blocks that aren't already dispatched. The way it work is by using the new notification API for GCD introduced in OS X 10.10 and iOS 8. Each chaining block is called when the previous queue has finished.

...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. We feel that Katana helped us a lot since we started using it in production. Our applications have been downloaded several millions of times and Katana really helped us scale them quickly and efficiently. ...
