This isn’t Core Data

This article is intended as a companion to Apple’s video and does not replace it in any way. However, I find having a text file like this much more helpful than just a video but I’m sure you’ll let me know in the comments how useful this is.

Swift Data

Uses the new Swift Macros to make this seamless.

In the repo I’ve added my project with the files, and to make this work in the storage section I selected Swift Data.

Model Macro

@Model defines scheme with code. This adds functionality with additional metadata by decorating a model with the annotation @Model

import SwiftData

@Model
class Trip {
    var name: String
    var destination: String
    var endDate: Date
    var startDate: Date
 
    var bucketList: [BucketListItem]? = []
    var livingAccommodation: BucketListItem?
}
