Swift local notification custom alert sound with label.text value

Question

I am trying to implement label text read and assign to local notification sound. Whenever local notification trigger It should make sound like "Hey your +label.text+ file downloaded.

Please help me to make above scenarion.

let content = UNMutableNotificationContent()
content.title = "Title"
content.body = "Body"
content.sound = UNNotificationSound.default()

let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 5, repeats: false)

let request = UNNotificationRequest(identifier: "TestIdentifier", content: content, trigger: trigger)
UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)

I have text to speech but I don't how to merge both

import AVFoundation

let string = "Hello, World!"
let utterance = AVSpeechUtterance(string: string)
utterance.voice = AVSpeechSynthesisVoice(language: "en-US")

let synth = AVSpeechSynthesizer()
synth.speak(utterance)

Answer 1

It does not look like possible in iOS. Custom notification sound should be an instance of the UNNotificationSound class, AVSpeechSynthesisVoice can't help you with this.

content.sound = UNNotificationSound(named: soundName)
