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...

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. ...

...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. ...

A simple and beautiful chart lib with animation used in Piner and CoinsMan for iOS. PNChart works on iOS 7.0+ and is compatible with ARC projects. If you need support for iOS 6, use PNChart <= 0.8.1. Note that 0.8.2 supports iOS 8.0+ only, 0.8.3 and newer supports iOS 7.0+. It depends on the following Apple frameworks, which should already be included with most Xcode templates, Foundation.framework, UIKit.framework, CoreGraphics.framework, and QuartzCore.framework.

NJKWebViewProgress is a progress interface library for UIWebView. Currently, UIWebView doesn't have an official progress interface. You can implement a progress bar for your in-app browser using this module. NJKWebViewProgress doesn't use CocoaTouch's private methods. It's AppStore safe. This repository contains iOS 7 Safari style bar NJKWebViewProgressView. You can choose NJKWebViewProgressView, UIProgressView or your custom bar. You can determine the current state of the document by...
