In this Swift Data Tutorial, We’ll be taking a look at migrations in Swift Data. We’ll take a look at how we can add versioning to our Swift Data Schema and see how it evolves over time by adding new features or tweaking existing functionality.

We’ll also look at custom migrations and lightweight migrations in SwiftData too. To see the difference and when to use each one. We’ll see how to manage this using a Migration Plan in SwiftData and modelling our schema using the VersionSchema API.

We’ll also discuss how to test swiftdata migrations too with some handy tools to help you speed up development.
