Swift 6 Migration Resources
Swift 6 was introduced the 16th of September 2024. This site is a collection of resources to help you migrate your Swift code to Swift 6.
This is a collection of resources to help you migrate your Swift code to Swift 6. This site is a work in progress and will be updated as more resources become available. The resources are not exhaustive and may not cover all aspects of the migration process. I’m not affiliated with Apple or the Swift team. This site is not an official resource for Swift 6 migration.
Getting started
Read the Swift 6 release notes to learn about the new features and changes in Swift 6.
Books1

Official migration guide
A great point to start is to read the official migration guide for Swift Concurrency. You can find it here. It covers the most important changes and how to migrate your code to the new concurrency model.
