I am trying to store usdz files with SwiftData for now.
I am converting usdz to data, then storing it with SwiftData
My model
import Foundation
import SwiftData
import SwiftUI
@Model
class Item {
var name: String
@Attribute(.externalStorage)
var usdz: Data? = nil
var id: String
init(name: String, usdz: Data? = nil) {
self.id = UUID().uuidString
self.name = name
self.usdz = usdz
}
}
My function to convert usdz to data. I am currently a local usdz just to test if it is going to work.
func usdzData() -> Data? {
do {
guard let usdzURL = Bundle.main.url(forResource: "tv_retro", withExtension: "usdz") else {
fatalError("Unable to find USDZ file in the bundle.")
}
let usdzData = try Data(contentsOf: usdzURL)
return usdzData
} catch {
print("Error loading USDZ file: \(error)")
}
return nil
}
Loading the items
@Query private var items: [Item]
...
var body: some View {
...
ForEach(items) { item in
HStack {
Model3D(?????) { model in
model
.resizable()
.scaledToFit()
} placeholder: {
ProgressView()
}
}
}
...
}
How can I load the Model3D?
I have tried:
Model3D(data: item.usdz)
Gives me the errors:
Cannot convert value of type '[Item]' to expected argument type 'Binding<C>'
Generic parameter 'C' could not be inferred
Both errors are giving in the ForEach.
I am able to print the content inside item:
ForEach(items) { item in
HStack {
Text("\(item.name)")
Text("\(item.usdz)")
}
}
This above works fine for me.
The item.usdz prints something like Optional(10954341 bytes)
I would like to know 2 things:
Is this the correct way to save usdz files into SwiftData? Or should I use FileManager? If so, how should I do that?
Also how can I get the usdz from the storage (SwiftData) to my code and use it into Model3D?
