I have been working on an app and using the SwiftData Model with the @Model macro. I noticed a while back that it doesn’t support the CKAsset data type b/c it does not conform to the PersistentModel protocol. I’m also assuming that’s b/c it does not conform to the Codable protocol.

I was hoping to use CKAsset as my data type b/c I’m uploading media; images, and movies. I’m using the photo picker to store and save media.

imageData = try? await item.loadTransferable(type: Data.self)

e.g. I save the value of imageData to my model to the record asset.

What I did instead was to use the data type Data. So far during development, this has seemed to work ok. Here is my model: (P.S. I’m not sure if importing CloudKit here is necessary yet or not.)

import SwiftUI
import SwiftData
import CloudKit

@Model
class Media: Identifiable {
    var id: UUID = UUID()
    var albumID: UUID = UUID()
    var asset: Data? = nil
    var isCover: Bool = false
    var contentType: String = ""
    var timeStamp: Date = Date()
    var album: Album?
    
    init(albumID: UUID = UUID(), asset: Data? = nil, isCover: Bool = false, contentType: String = "", timeStamp: Date = Date()) {
        self.albumID = albumID
        self.asset = asset
        self.isCover = isCover
        self.contentType = contentType
        self.timeStamp = timeStamp
    }
}

I noticed last night all of the sudden it stopped using my defined asset in my model and created a new record in CloudKit called asset_CKAsset. Is this an issue or is Cloudkit just handling that conversion for me from Data to CKSsset? I wanted to make sure my app continues to work as intended, there aren’t any limitations to using a data type of Data for this that I’m not aware of, etc.

Any thoughts or recommendations would be greatly appreciated.
