How to connect iOS AVFoundation FrameWork to Adobe Animate with Adobe Air?

Thanks, I already saw that.
But there is no SWC or ANE.
I attached the path to AIR and that's not enough.

import flash.media.AVSpeechSynthesizer;
import flash.media.AVSpeechUtterance;

var synthesizer:AVSpeechSynthesizer = new AVSpeechSynthesizer();
var utterance:AVSpeechUtterance = new AVSpeechUtterance("Hello, world!");

Scéna 1, Layer 'skript', Frame 1, Line 20, Column 19 1172: Definition flash.media:AVSpeechSynthesizer could not be found.

Does this mean I have to program the ANE addon in xCode?
