It seems like you're asking about "NSStagedMigrationManager," but there is no specific mention of this in the provided context from the WWDC sessions. However, there are several sessions related to migration and data management that might be of interest:
-
Migrate your app to Swift 6: This session discusses the process of migrating apps to Swift 6, including enabling concurrency checking and ensuring data-race safety. It provides a structured approach to migration, which might be relevant if you're dealing with code migration or updates. You can find more details in the session Migrate your app to Swift 6 (03:20).
-
Create a custom data store with SwiftData: This session covers creating custom data stores with SwiftData, including features like migration, history tracking, and CloudKit sync. It might be useful if you're looking into data management and migration strategies. More information can be found in the session Create a custom data store with SwiftData (04:50).
-
Track model changes with SwiftData history: This session focuses on tracking changes in your data store over time, which can be useful for understanding data migrations and updates. You can explore this topic further in the session Track model changes with SwiftData history (05:18).
If you have specific questions about these sessions or need more detailed information, feel free to ask!

What’s new in Swift
Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.

What’s new in SwiftData
SwiftData makes it easy to add persistence to your app with its expressive, declarative API. Learn about refinements to SwiftData, including compound uniqueness constraints, faster queries with #Index, queries in Xcode previews, and rich predicate expressions. Join us to explore how you can use all of these features to express richer models and improve performance in your app. To discover how to build a custom data store or use the history API in SwiftData, watch “Create a custom data store with SwiftData” and “Track model changes with SwiftData history”.

Track model changes with SwiftData history
Reveal the history of your model’s changes with SwiftData! Use the history API to understand when data store changes occurred, and learn how to use this information to build features like remote server sync and out-of-process change handing in your app. We’ll also cover how you can build support for the history API into a custom data store.

Create a custom data store with SwiftData
Combine the power of SwiftData’s expressive, declarative modeling API with your own persistence backend. Learn how to build a custom data store and explore how to progressively add persistence features in your app. To get the most out of this session, watch “Meet SwiftData” and “Model your schema with SwiftData” from WWDC23.

Build a great Lock Screen camera capture experience
Find out how the LockedCameraCapture API can help you bring your capture application’s most useful information directly to the Lock Screen. Examine the API’s features and functionality, learn how to get started creating a capture extension, and find out how that extension behaves when the device is locked.

Support semantic search with Core Spotlight
Learn how to provide semantic search results in your app using Core Spotlight. Understand how to make your app’s content available in the user’s private, on-device index so people can search for items using natural language. We’ll also share how to optimize your app’s performance by scheduling indexing activities. To get the most out of this session, we recommend first checking out Core Spotlight documentation on the Apple Developer website.

Port advanced games to Apple platforms
Discover how simple it can be to reach players on Apple platforms worldwide. We’ll show you how to evaluate your Windows executable on Apple silicon, start your game port with code samples, convert your shader code to Metal, and bring your game to Mac, iPhone, and iPad. Explore enhanced Metal tools that understand HLSL shaders to validate, debug, and profile your ported shaders on Metal.

Migrate your app to Swift 6
Experience Swift 6 migration in action as we update an existing sample app. Learn how to migrate incrementally, module by module, and how the compiler helps you identify code that’s at risk of data races. Discover different techniques for ensuring clear isolation boundaries and eliminating concurrent access to shared mutable state.
