So far, everything you’ve modeled in your entities have been primitive data types - Ints, Strings, Dates and Booleans. What if you wanted to model data that didn’t fit into one of these categories? What about media such as audio, video or an image? Can Core Data handle this? It most certainly can.

import UIKit

@NSManaged public var attachment: UIImage?

@State var attachment: UIImage?

.sheet(isPresented: $showImagePicker) {
	ImagePicker(selectedImage: $attachment)
}

launchpad: self.launchpad,
attachment: self.attachment,
tags: tags,

if let attachment = attachment {
	Image(uiImage: attachment)
	  .resizable()
	  .aspectRatio(contentMode: .fit)
} else {
	Button("Pick Image") {
	  showImagePicker.toggle()
	}
}

launchpad: String,
attachment: UIImage?,
tags: Set<Tag> = [],
    
//.....

launch.attachment = attachment

@NSManaged public var attachment: Data?

launch.attachment = attachment?.jpegData(compressionQuality: 1) ?? Data()
