SwiftData for Server-Side Swift

Share your SwiftData models between iOS apps and Vapor servers. Write once, run everywhere with 100% API compatibility.

Same Models, Everywhere

Define your models once and use them on iOS, macOS, and your Vapor server.

// Works on iOS, macOS, and Server
@Model
final class User {
    var name: String

    @Attribute(.unique)
    var email: String

    @Relationship(deleteRule: .cascade)
    var posts: [Post] = []

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