Swift Basics
The session titled "A Swift Tour: Explore Swift’s features and design" from WWDC 2024 provides an overview of Swift's core features and design principles. Here are some key points covered in the session:
-
Value Types: Swift emphasizes the use of value types, such as structs and enums, which are copied when assigned to a new variable or passed to a function. This makes it easier to reason about code, especially in concurrent programming. A Swift Tour: Explore Swift’s features and design
-
Type Safety: Swift is a type-safe language, meaning every variable has a type at compile time. This helps catch errors early in the development process. A Swift Tour: Explore Swift’s features and design
-
Error Handling: Swift provides robust error handling with the use of
throwsandtrykeywords, ensuring that code is structured to handle all possibilities. A Swift Tour: Explore Swift’s features and design -
Code Organization: Swift supports modules and packages for organizing code. A module is a collection of source files built together, and packages can be distributed as a collection of modules. A Swift Tour: Explore Swift’s features and design
-
Concurrency: Swift provides tools for handling concurrency, such as actors, which help manage data races and ensure thread safety. A Swift Tour: Explore Swift’s features and design
These features make Swift a powerful and safe language for developing applications across Apple's platforms and beyond. If you are interested in learning more about Swift's features, you can explore the session A Swift Tour: Explore Swift’s features and design.

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”.
A Swift Tour: Explore Swift’s features and design
Learn the essential features and design philosophy of the Swift programming language. We’ll explore how to model data, handle errors, use protocols, write concurrent code, and more while building up a Swift package that has a library, an HTTP server, and a command line client. Whether you’re just beginning your Swift journey or have been with us from the start, this talk will help you get the most out of the language.
