To make SwiftData constructs, you can start by using the SwiftData framework, which allows you to model and persist your app's data across Apple's platforms. Here's a brief overview of how you can work with SwiftData:
-
Import the Framework: Begin by importing the SwiftData framework into your project.
-
Define Models: Use the
modelmacro to define your data models. This macro is the core of SwiftData, allowing you to specify the schema for your data. -
Customize Schema: You can further refine your models using attributes to specify behaviors on properties and relationships to describe how models relate to one another. SwiftData also supports indexing and unique constraints to optimize queries.
-
Model Container: Use the
modelContainermodifier on your app'sWindowGroupto inform the view hierarchy about your models. This allows your views to query and display data from the model container. -
Custom Data Stores: If needed, you can configure custom data stores to use alternative backends like SQLite or a remote web service.
For more detailed information, you can refer to the session What’s new in SwiftData (00:57) which covers adopting SwiftData, customizing schemas, and optimizing queries.
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”.
Swift Charts: Vectorized and function plots
The plot thickens! Learn how to render beautiful charts representing math functions and extensive datasets using function and vectorized plots in your app. Whether you’re looking to display functions common in aerodynamics, magnetism, and higher order field theory, or create large interactive heat maps, Swift Charts has you covered.
Platforms State of the Union
Discover the newest advancements on Apple platforms.
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.
Support real-time ML inference on the CPU
Discover how you can use BNNSGraph to accelerate the execution of your machine learning model on the CPU. We will show you how to use BNNSGraph to compile and execute a machine learning model on the CPU and share how it provides real-time guarantees such as no runtime memory allocation and single-threaded running for audio or signal processing models.
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.
