This article introduces SwiftUI, compares it with other declarative UI frameworks, explains its rendering pipeline, lifecycle, data‑binding mechanisms, language features, and discusses how Qunar has adopted SwiftUI and migrated parts of its native iOS codebase from Objective‑C to Swift.
The article details how AcFun transitioned its iOS codebase from Objective‑C to Swift, describing Swift's origins, Apple’s strategic push, the company’s architectural evolution, mixed‑language challenges, performance gains, and the adoption of modern frameworks such as SwiftUI, Combine, and RxSwift.
This article explains the concept of Schedulers in the Swift Combine framework, compares the default scheduling behavior with explicit subscribe(on:) and receive(on:) operators, demonstrates various Scheduler implementations (ImmediateScheduler, RunLoop, DispatchQueue, OperationQueue) through detailed code examples, and provides practical guidance for managing thread execution in reactive iOS applications.
This article provides a comprehensive overview of Apple’s Combine framework—explaining its core concepts such as publishers, subscribers, subjects, operators, and lifecycle management—while demonstrating custom implementations, MVVM integration, and performance comparisons with RxSwift through detailed code examples.
