tattn/ios-architectures

This system is an iOS application designed to demonstrate and compare multiple architectural patterns, specifically MVC, MVP, MVVM, and VIPER. It provides a unified codebase where each pattern is implemented as a separate Xcode scheme for easy testing. The project standardizes UI updates to the main thread and manages dependencies like SWXMLHash and Kingfisher.

The project now includes shared Xcode build schemes for each architectural pattern (CleanArchitecture, MVC, MVP, MVVM, and VIPER), allowing developers to easily build and run each variant from the Xcode scheme menu. Additionally, the project has been updated to Swift 4.0, enabling the use of new language features and improved compiler warnings.

A new CatCollectionViewLayout class is introduced to replace inline UICollectionViewFlowLayout configuration across multiple architectural patterns (MVC, MVP, MVVM, VIPER, and Clean Architecture). This change also updates the UI update logic to explicitly dispatch to the main thread using DispatchQueue.main.async, and switches several optional chaining calls to force-unwraps for view models and presenters. Additionally, the app's network security configuration is updated to allow arbitrary loads, and the app icon set is expanded to include 20x20 and 83.5x83.5 sizes for iPad and marketing.

The project's CocoaPods dependencies (SWXMLHash and Kingfisher) have been updated to versions 4.2.5 and 4.5.0 respectively, removing previous version constraints. The README has been updated to include a Swift 4.0 badge, a visual sample app screenshot, and a TODO list of future architecture implementations.
