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. ...

Reactive extensions to Cocoa frameworks, built on top of ReactiveSwift. ReactiveSwift offers composable, declarative and flexible primitives that are built around the grand concept of streams of values over time. These primitives can be used to uniformly represent common Cocoa and generic programming patterns that are fundamentally an act of observation. ReactiveCocoa wraps various aspects of Cocoa frameworks with the declarative ReactiveSwift primitives. Interactive UI components expose Signals for control events and updates in the control value upon user interactions. ...

...Its async and await helpers allow asynchronous tasks to be written in a more sequential style. Promises can be cancelled through invalidation tokens and executed on configurable Grand Central Dispatch queues. Operators include timeout, retry, recover, validate, map, zip, all, any, defer, pass, and always. Hydra supports Apple platforms and Linux and can be integrated through common Swift dependency-management systems.

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.

Repeat is a lightweight Swift timer library built on Grand Central Dispatch as an alternative to NSTimer. Its compact APIs create repeating or one-time timers that can operate on background queues. Timer instances can be paused, started, resumed, and reset without creating replacements. Multiple observers can subscribe to the same timer, while weak callback references help reduce unwanted retention.
