You can install SoundKit using Swift Package Manager. Simply add the following line to your Package.swift file:

dependencies: [
    .package(url: "", from: "1.0.0")



SoundPlayer is the main class in SoundKit responsible for playing sounds. Here’s how you can use it:

  1. Start the sound engine by calling SoundPlayer.start(). It’s recommended to call this method as soon as possible (e.g. in your AppDelegate or SceneDelegate) to prevent delays when playing the first sound.

  2. Play a sound by calling, passing in an object that conforms to the Sound protocol.

Here’s an example:

// Start the sound engine

// Play a sound

You can also customize the volume and number of loops for each sound by setting the corresponding properties in your Sound object. If you want a sound to loop indefinitely, simply set the isLoop property to true.


Sound is a protocol that you can adopt to define your own sounds. Here are the properties you can customize:

  • fileName: The name of the sound file (without the extension).
  • fileExtension: The extension of the sound file (e.g. “mp3”).
  • haptic: An optional object that conforms to the Haptic protocol. If provided, the haptic will be played whenever the sound is played.
  • numberOfVariations: The number of variations of the sound file (e.g. if you have “sound.mp3” and “sound_1.mp3”, set this to 2).
  • volume: The volume of the sound (0.0 to 1.0).
  • isLoop: Whether the sound should loop indefinitely.

Here’s an example:

struct MySound: Sound {
    var fileName = "my_sound"
    var fileExtension = "mp3"
    var haptic = MyHaptic()
    var numberOfVariations = 3
    var volume: Float = 0.5
    var isLoop = true


Haptic is a protocol that you can adopt to define your own haptics. Here are the properties you can customize:

  • style: The feedback style of the haptic.
  • intensity: The intensity of the haptic (0.0 to 1.0).

Here’s an example:

struct MyHaptic: Haptic {
    var style = .heavy
    var intensity: CGFloat = 1.0
