This article shares a detailed iOS interview journey—including Baidu, NetEase, and Alibaba rounds—along with algorithm questions, Objective‑C runtime insights, practical coding challenges, and actionable preparation strategies to help developers land their dream mobile development jobs.
This guide shows how to set view corner radius directly in Interface Builder using @IBInspectable, covering simple code approaches, runtime attributes, Swift extensions, and Objective‑C categories, with full code examples for both Swift and Objective‑C implementations.
This article explains how to integrate Apple Pay’s in‑app payment feature into an iOS application, compares it with traditional third‑party payment SDKs, and provides detailed implementation steps, code samples, server‑side decryption, transaction handling, and practical tips for a seamless user experience.
This article walks developers through the motivations, technical differences, and practical steps for creating, using, and publishing iOS frameworks, covering static vs. dynamic libraries, dependency managers, API design, versioning, CI, and release strategies to help produce robust, reusable components.
This step‑by‑step guide shows how to set up a GitHub repository, add the required source, podspec, demo, README and LICENSE files, validate the pod, push the code, and finally submit the podspec to the official CocoaPods Specs so others can use your Swift library.
The article discusses practical technology selection for mobile app development, weighing native versus H5 approaches, choosing between Objective‑C and Swift, and comparing MVC, MVP, and MVVM architectures, emphasizing decisions based on team resources, project timelines, and long‑term maintainability.
This article explains practical Swift optimization techniques—including enabling compiler optimizations, whole‑module compilation, reducing dynamic dispatch with final and private, using value types and ContiguousArray, unchecked arithmetic, generic specialization, unmanaged references, and class‑only protocols—to improve runtime speed and binary size for iOS apps.
From its 1960s origins in Simula and Smalltalk to its evolution through NeXT, Objective‑C introduced groundbreaking dynamic features, yet despite Swift’s rise, Apple continues to invest in the language, ensuring its ongoing relevance in the iOS/macOS ecosystem.
This article examines the architectural differences, performance, consistency, and security trade‑offs between Ceph and Swift object storage in OpenStack, offering guidance on selecting the appropriate solution based on deployment scale, multi‑region needs, and security requirements.
This article provides a comprehensive overview of OpenStack Swift, covering its background, consistent hashing, quorum-based consistency model, ring data structure, hierarchical data model, system architecture, component responsibilities, and RESTful API usage for scalable object storage.
Chris Lattner, the original creator of LLVM and Clang, now leads Apple’s Developer Tools division and has driven the development of Swift since 2010, integrating his compiler expertise, fostering interactive tools like Xcode Playgrounds, and shaping modern programming education.
Apple’s Swift language, introduced at WWDC 2014, offers a modern, LLVM‑compiled syntax with playgrounds, optional typing, clear variable and constant declarations, robust control‑flow constructs, first‑class functions and closures, class inheritance, protocols, extensions, generics, and safe optional handling, making development for macOS and iOS both expressive and less error‑prone.
