Reachability is a lightweight Objective-C wrapper around Apple’s SCNetworkReachability that reports whether the network is reachable and via which interface (Wi-Fi or cellular). It exposes both notifications and blocks so you can react to connectivity changes without polling. Typical usage is to gate network requests, disable online-only UI, and show graceful messaging when connectivity drops. The implementation is careful about threading and runloop scheduling so events arrive reliably...

CocoaLumberjack is a fast & simple, yet powerful & flexible logging framework for macOS, iOS, tvOS and watchOS. First, install CocoaLumberjack via CocoaPods, Carthage, Swift Package Manager or manually. Then use DDOSLogger for iOS 10 and later, or DDTTYLogger and DDASLLogger for earlier versions to begin logging messages. Carthage is a lightweight dependency manager for Swift and Objective-C. It leverages CocoaTouch modules and is less invasive than CocoaPods. As of CocoaLumberjack 3.6.0,...

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. ...

...You can also include it into your project by adding the source files directly, but you should probably be using a dependency manager to keep up to date. GCDAsyncSocket is a TCP/IP socket networking library built atop Grand Central Dispatch. Automatically accept incoming connections over both IPv4 and IPv6 with a single instance of this class. No more worrying about multiple sockets. Secure your socket with ease using just a single method call. Available for both client and server sockets. It runs entirely within its own GCD dispatch_queue, and is completely thread-safe. ...

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.

...Instead of simple how-to recipes, the project collects detailed explanations, system internals analyses, and real-world insights into core subsystems like memory management (ARC), threading and Grand Central Dispatch, Objective-C/Swift runtime behavior, UIKit rendering pipelines, and effective use of concurrency. It also covers architectural and performance topics such as dynamic layout optimization, view lifecycle subtleties, Swift language pitfalls, and integration with low-level APIs such as Metal or CoreAnimation. By aggregating authoritative references, experiments, and code snippets, the guide helps developers reason through tradeoffs, debug subtle issues, and architect large-scale iOS systems.
