I actually managed to get it to work in a different way. Before, I was trying to access the static Item variables itself, but what I should have done is fetch from the model context after I inserted the static Item objects into my model.
#Preview {
let preview = Preview(Item.self, Category.self)
preview.addExamples(Category.sampleCategories)
preview.addExamples(Item.sampleItems)
// SOLUTION
let samples = preview.getSamples(Item.self)
return NavigationStack {
ItemDetailsView(item: samples[0])
.modelContainer(preview.container)
}
where getSamples() is a generic function defined in the Preview class as
@MainActor
func getSamples<T: PersistentModel>(_ model: T.Type) -> [T] {
let context = container.mainContext
let request = FetchDescriptor<T>()
do {
let samples = try context.fetch(request)
return samples
} catch {
print("Failed to fetch model: \(error)")
return []
}
}
Not sure if this is the "proper" way of doing it, but it worked.
