There is no native iOS API to detect if the mute switch is enabled/disabled on a device.

The general principle to check if the device is muted is to play a short sound and detect the length it took to play. From this length we can determine if it was muted or not.

This library is effectively a Swift variant of SoundSwitch.

Has a trigger rate of 1 second.


To run the example project, clone the repo, and run pod install from the Example directory first.


import UIKit
import Mute

class ViewController: UIViewController {

    @IBOutlet weak var label: UILabel! {
        didSet {
            self.label.text = ""

    override func viewDidLoad() {

        // Notify every 2 seconds
        Mute.shared.checkInterval = 2.0

        // Always notify on interval
        Mute.shared.alwaysNotify = true

        // Update label when notification received
        Mute.shared.notify = { [weak self] m in
            self?.label.text = m ? "Muted" : "Not Muted"

        // Stop after 5 seconds
        DispatchQueue.main.asyncAfter(deadline: .now() + 5.0) {
            Mute.shared.isPaused = true

        // Re-start after 10 seconds
        DispatchQueue.main.asyncAfter(deadline: .now() + 10.0) {
            Mute.shared.isPaused = false




Mute is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'Mute'
