Hi all,

I am trying to update my audio recorder app to iOS 17 and was wondering how I might be able to use SwiftData to store audio files so that they can be uploaded to CloudKit. Right now I'm using FileManager, but here is what I have so far:

import Foundation
import AVFoundation

@MainActor
class Recorder: NSObject, ObservableObject, AVAudioRecorderDelegate {
    private var audioRecorder: AVAudioRecorder!

    func record() throws {
        let date = Date()
        let dateFormatter = DateFormatter()
        dateFormatter.dateFormat = "h:mm a, MMM d yyyy"

        // The user grants access. Present recording interface.
        let recordingSession = AVAudioSession.sharedInstance()
        do {
            try recordingSession.setCategory(.playAndRecord, mode: .default)
            try recordingSession.setActive(true)
        } catch {
            throw Errors.FailedToInitSessionError
        }
        let path = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
        let fileName = path.appendingPathComponent("\(dateFormatter.string(from: date)).m4a")

        let settings = [
            AVFormatIDKey: Int(kAudioFormatMPEG4AAC),
            AVSampleRateKey: 44100,
            AVNumberOfChannelsKey: 1,
            AVEncoderAudioQualityKey: AVAudioQuality.high.rawValue
        ]

        do {
            audioRecorder = try AVAudioRecorder(url: fileName, settings: settings)
            audioRecorder.prepareToRecord()
            audioRecorder.record()

        } catch {
            throw Errors.FailedToRecordError
        }
    }

    func stop() {
        audioRecorder.stop()
    }

    nonisolated func audioRecorderDidFinishRecording(_ recorder: AVAudioRecorder, successfully flag: Bool) {
        if !flag {
            print("Recording failed")
        }
    }
}

And here is the class I made for SwiftData, but haven't used yet:

import Foundation
import SwiftData
@Model class Recording {
    private var name : String
    private var date : Date
    private var url : URL

    init(url: URL) {
        self.name = ""
        self.date = .now
        self.url = url
    }    
}

Any guidance towards the right direction would help immensely, thanks so much in advance!
