Make sure you setup and activate your AVAudioSession.

import AVFoundation
let session: AVAudioSession = AVAudioSession.sharedInstance()
do {
    try session.setPreferredSampleRate(44_100)
    // https://stackoverflow.com/questions/51010390/avaudiosession-setcategory-swift-4-2-ios-12-play-sound-on-silent
    if #available(iOS 10.0, *) {
        try session.setCategory(.playAndRecord, mode: .default, options: [.allowBluetooth])
    } else {
        session.perform(NSSelectorFromString("setCategory:withOptions:error:"), with: AVAudioSession.Category.playAndRecord, with:  [AVAudioSession.CategoryOptions.allowBluetooth])
    }
    try session.setMode(AVAudioSessionModeDefault)
    try session.setActive(true)
} catch {
}

SRT Usage

let srtConnection: SRTConnection = SRTConnection()
let srtStream: SRTStream = SRTStream(connection: srtConnection)
srtStream.attachCamera(DeviceUtil.device(withPosition: .back))
srtStream.attachAudio(AVCaptureDevice.defaultDevice(withMediaType: AVMediaTypeAudio))
srtStream.publish("hello")
srtConnection.connect("srt://host:port?option=foo")

var hkView: HKView = HKView(frame: view.bounds)
hkView.attachStream(srtStream)

// add ViewController#view
view.addSubview(hkView)
