Description

Since its introduction in 2019, the SwiftUI architecture has sparked ongoing debates. Over the past two years, I've dedicated myself to exploring various patterns and best practices aimed at simplifying the development of SwiftUI applications.I've gained a comprehensive understanding of SwiftUI architecture and how to utilize it in accordance with Apple's guidelines. This course is the culmination of my years of research and hands-on experience. Its aim is to assist you in mastering SwiftUI architecture and embracing best practices throughout your development journey.Course OverviewIn this course, we will cover a wide range of topics crucial for building robust SwiftUI applications. Below is a detailed outline of what you can expect to learn:Limitations of MVVM in SwiftUIModel-View-ViewModel (MVVM) is a popular design pattern in iOS development. However, it presents unique challenges when applied to SwiftUI:- State Management: Managing state across views can become cumbersome.- Complexity: ViewModels can grow large and complex.- Performance Issues: Improper state handling can lead to performance bottlenecks.We will delve into these limitations and explore alternative approaches to streamline your SwiftUI development process.Migrating from MVVM to MVSwiftUI encourages a more straightforward approach to architecture, often favoring a Model-View (MV) pattern over MVVM. In this module, you will learn:- Differences between MVVM and MV: Understanding the core distinctions and when to apply each pattern.- Migration Strategies: Step-by-step guidance on transitioning your existing MVVM codebase to MV.- Best Practices: Leveraging MV to simplify your SwiftUI code.Understanding Aggregate Models/StoresAggregating models and stores can significantly improve data management in SwiftUI applications. Key topics include:- Data Aggregation Techniques: Methods for combining multiple data sources.- State Management: Efficiently managing state in aggregate models.- Practical Examples: Implementing aggregate stores in real-world scenarios.SwiftUI ViewsDesigning and structuring views effectively is critical in SwiftUI. This section will cover:- View Composition: Building reusable and modular views.- Declarative Syntax: Utilizing SwiftUI's declarative syntax to create intuitive and maintainable UIs.- Performance Optimization: Techniques to ensure your views are performant.ValidationInput validation is a common requirement in applications. Here, we will explore:- Validation Patterns: Different approaches to input validation in SwiftUI.- Real-time Feedback: Providing users with immediate feedback on their input.- Best Practices: Ensuring validation logic is maintainable and scalable.NavigationSwiftUI's navigation system offers unique capabilities and challenges. Topics include:- NavigationStack: Understanding and using NavigationStack for hierarchical navigation.- NavigationLinks: Proper usage of NavigationLinks and managing their state.- Complex Navigation Flows: Handling complex navigation scenarios.TestingTesting is essential for ensuring the reliability of your applications. This module will focus on:- Unit Testing: Writing and running unit tests for your SwiftUI components.- UI Testing: Automating UI tests to verify user interactions.- Testing Strategies: Best practices for integrating testing into your development workflow.UIKit & SwiftUI InteroperabilityMany existing projects still rely on UIKit, and interoperability is often required. In this section, you will learn:- Bridging Techniques: How to integrate UIKit components into SwiftUI and vice versa.- Hybrid Applications: Strategies for developing hybrid applications that use both frameworks.- Real-world Examples: Practical examples of interoperability in action.By the end of this course, you will have a solid understanding of SwiftUI architecture and the skills to implement best practices in your projects. Let's embark on this journey to master SwiftUI together!
