SwiftySound is a simple library that lets you deal with Swift sounds easily.

Static methods
Sound.play(file: "dog.wav")
Sound.play(url: fileURL)

More advanced example:

Sound.play(file: "dog", fileExtension: "wav", numberOfLoops: 2)

The above will play the sound three times.

Specify a negative number of loops to play the sound continously in an infinite loop:

Sound.play(file: "dog", fileExtension: "wav", numberOfLoops: -1)

Stop currently playing sounds:


Enable/disable all sounds:

Sound.enabled = true
Sound.enabled = false

The value of Sound.enabled property will be automatically persisted in UserDefaults and restored on the next launch of your app.

Change sound categories. SwiftySound provides a simple way of changing sound category:

Sound.category = .ambient

This changes the category of the underlying shared AVAudioSession instance. The default value is SoundCategory.ambient. Due to AVAudioSession architecture, this property is not available on macOS.

Creating instances of Sound class

You can also create an instance of a Sound class and store it somewhere in your app.

let mySound = Sound(url: fileURL)

Creating an instance has more benefits like the ability to adjust the volume and playback callbacks.

Change the volume

You can change the volume of each Sound instance.

mySound.volume = 0.5

The value of volume property should be between 0.0 and 1.0, where 1.0 is the maximum.


You can pass a callback to the play method. It will be played after the sound finished playing. For looped sounds, the callback will be called once after the last loop has been played.

mySound.play { completed in
    print("completed: \(completed)")

The callback is not called if the sound was stopped, interrupted or in case of a playback error.

Installation with CocoaPods

CocoaPods is a dependency manager which automates and simplifies the process of using third-party libraries in your projects. See the Get Started section for more details.

platform :ios, '8.0'
pod 'SwiftySound'

Installation with Carthage

Carthage is a lightweight dependency manager for Swift and Objective-C. It leverages CocoaTouch modules and is less invasive than CocoaPods.

To install with carthage, follow the instruction on Carthage

github "adamcichy/SwiftySound"

Installation with Swift Package Manager

The Swift Package Manager is a tool for managing the distribution of Swift code. Just add the url of this repo to your Package.swift file as a dependency:

import PackageDescription

let package = Package(
    name: "YourPackage",
    dependencies: [
        .Package(url: "https://github.com/adamcichy/SwiftySound.git",
                 majorVersion: 0)

Then run swift build and wait for SPM to install SwiftySound.

Manual installation

Drop the Sound.swift file into your project, link against AVFoundation.framework and you are ready to go.
