FAQPage Schema
How do I migrate my Swift codebase to structured concurrency with async/await?

Migrate to Swift 6 structured concurrency by codifying async/await patterns and enforcing safe concurrency practices. This guide provides specific patterns to restructure closure-based asynchronous code into maintainable, thread-safe implementations.

What is the best way to choose an architecture for a Swift 6 project?

Choosing a Swift 6 architecture requires evaluating MVC, MVVM, and VIPER against your project's complexity. This guide codifies architectural requirements to ensure your chosen pattern aligns with modern concurrency and maintainability standards.

Does this guide cover best practices for both SwiftUI and UIKit?

Yes, it covers best practices for both SwiftUI and UIKit. The guidelines address state management, lifecycle, interoperability, and testing across both UI frameworks to ensure consistent development patterns.

How do I manage dependencies and code style in a scalable Swift 6 codebase?

Manage Swift 6 dependencies and code style by applying consistent formatting and dependency usage guidelines. The guide enforces specific rules for dependency management to ensure your codebase remains scalable and maintainable.

Can I audit an existing iOS project for Swift 6 compliance?

Yes, you can audit an existing Swift 6 project by comparing its current architecture, concurrency patterns, UI implementation, and dependency usage against the codified best practices in this guide.

Why does Swift 6 require updates to my existing architecture and concurrency patterns?

Swift 6 requires architecture and concurrency updates to enforce safe concurrency and eliminate data races. The guide helps align your existing patterns with strict concurrency requirements and modern async/await workflows.
