How to use SwiftData with a Singleton within a SwiftUI app


To use SwiftData in a Singleton within a SwiftUI app, initialize the modelContext within the initializer. Then apply the container to views for seamless use.
This tutorial is based on our upcoming app Object Capture Pro, which uses a Singleton to manage all the SwiftData operations in a way that is interoperable with standard SwiftUI SwiftData actions and updates.

Step One: Initialize the Singleton SwiftData Container

Add the ModelContainer to the Singleton, and within the init function set it.
Step Two: Apply Container to Views

To apply the modelContext to a view in a way that performs as expected, use code similar to the one below.
Please replace _SINGLETON_ with the name of your singleton class.
.modelContainer(SINGLETON.modelContainer)
Step Three: Use within a View

Within a view, you can now use the model context as expected.
When changes are made, it will also update as expected.
