What kind of data can be a SwiftData property?

Updated for Xcode 15

SwiftData is capable of storing a variety of data, but specifically the following:

1. Any class that uses the @Model macro.
2. Any struct that conforms to the Codable protocol.
3. Any enum that conforms to the Codable protocol, even if it includes raw values or associated values.

Important

If you intend to use options 2 or 3 in a hybrid app – using both SwiftData and Core Data side by side – it’s important that you use composite attributes in your Core Data code in order to retain compatibility.

For example, we could create a Status enum that has two cases, one of which has an associated value, then use that as one value inside

enum Status: Codable {
    case active, inactive(reason: String)
}

@Model
class User {
    var name: String
    var status: Status

    init(name: String, status: Status) {
        self.name = name
        self.status = status
    }
}
