ios – audio participant stutters when slider updates tvOS Swift app

I’m utilizing TvOSSlider in my television app to create a seek-bar and play audio monitor with AVAudioPlayer. My downside is that it’s stuttering each time i replace the seekbar/slider by means of code. So at present it’s set to stutter each 1.0seconds. UISlider is unavailable in tvOS that’s the reason i’m utilizing this completely different library.

func playAudio(url: URL, completion: (() -> Void)? = nil) {
    stopAudio()
    do {
        audioPlayer = strive AVAudioPlayer(contentsOf: url as URL)
        audioPlayer?.delegate = self
        audioPlayer?.prepareToPlay()
        audioPlayer?.play()
        isPaused = false
        // Begin the playback timer to replace the search bar
        DispatchQueue.important.async { [self] in
            // That is the place timer is about and replace Slider methodology is known as. I attempted to set it from 0.1 sec to five sec
            playbackTimer = Timer.scheduledTimer(timeInterval: 1.0, goal: self, selector: #selector(updateSlider), userInfo: nil, repeats: true)
        }
        completion?()
    } catch let error as NSError {
        print("Error initializing AVAudioPlayer: (error.localizedDescription)")
        completion?()
    }
}
// Replace the slider worth based mostly on the present playback time
@objc func updateSlider() {  // This perform will get known as above
    guard let audioPlayer = audioPlayer else { return }
    slider?.setValue(Float(audioPlayer.currentTime / audioPlayer.period), animated: true) // This line causes the stuttering
}

I’ve tried background DispatchQueue however it crashes the app saying slider.setvalue should be known as from important thread because it updates ui. I additionally tried taking part in audio within the background thread however that was a doomed thought to start with. Following is my audio supervisor code

import AVFAudio
import TvOSSlider

class AudioManager {
    static let shared = AudioManager()
    
    personal var audioPlayer: AVAudioPlayer?
    var playbackTimer: Timer?
    personal var isPaused = false
    var slider: TvOSSlider? // Add a reference to the slider
    
    personal init() { }
    
    func playAudio(url: URL, completion: (() -> Void)? = nil) {
        stopAudio()
        do {
            audioPlayer = strive AVAudioPlayer(contentsOf: url as URL)
            audioPlayer?.prepareToPlay()
            audioPlayer?.play()
            isPaused = false
            // Begin the playback timer to replace the search bar
            DispatchQueue.important.async { [self] in
                playbackTimer = Timer.scheduledTimer(timeInterval: 1.0, goal: self, selector: #selector(updateSlider), userInfo: nil, repeats: true)
            }
            completion?()
        } catch let error as NSError {
            print("Error initializing AVAudioPlayer: (error.localizedDescription)")
            completion?()
        }
    }
    
    func togglePlayPause() {
        guard let audioPlayer = audioPlayer else {
            return
        }
        
        if audioPlayer.isPlaying {
            audioPlayer.pause()
            playbackTimer?.invalidate()
            playbackTimer = nil
            isPaused = true
        } else {
            audioPlayer.play()
            playbackTimer = Timer.scheduledTimer(timeInterval: 1.0, goal: self, selector: #selector(updateSlider), userInfo: nil, repeats: true)
            isPaused = false
        }
    }

    func stopAudio() {
        audioPlayer?.cease()
        audioPlayer = nil
        isPaused = false
        
        playbackTimer?.invalidate()
        playbackTimer = nil
    }
    
    // MARK: - Slider strategies
    
    // Replace the slider worth based mostly on the present playback time
    @objc func updateSlider() {
        guard let audioPlayer = audioPlayer else { return }
        slider?.setValue(Float(audioPlayer.currentTime / audioPlayer.period), animated: true)
    }
    
    // Search to the specified place within the audio
    @objc func sliderValueChanged(_ sender: TvOSSlider) {
        guard let audioPlayer = audioPlayer else { return }
        let targetTime = TimeInterval(sender.worth) * audioPlayer.period
        audioPlayer.currentTime = targetTime
    }
    
}

And right here is my use of this in my opinion controller

import TvOSSlider

class MyViewController: UIViewController {
...

    @IBOutlet weak var tvosSlider: TvOSSlider!

    override func viewDidLoad() {
        tremendous.viewDidLoad()
        
        setupView()
        playSongFromUrl()
        getData()
        
    }

    func setupView(){
        
//        // Set the AudioManager's slider property
        AudioManager.shared.slider = tvosSlider
        AudioManager.shared.slider?.addTarget(AudioManager.shared, motion: #selector(AudioManager.sliderValueChanged(_:)), for: .valueChanged)
        ...
    }

    func play(url: URL) {
        AudioManager.shared.playAudio(url: url){
            self.stopLoader()
        }
    }
...
}
    

Now i’m unable to search out
