Build Status

SwiftAudio is an audio player written in Swift, making it simpler to work with audio playback from streams and files.


To see the audio player in action clone the repo and run the example project!
To run the example project, clone the repo, and run pod install from the Example directory first.


iOS 10.0+


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

pod 'SwiftAudio'



let player = QueuedAudioPlayer()
let audioItem = DefaultAudioItem(audioUrl: "someUrl", sourceType: .stream)
player.add(item: audioItem)

The player will load the track and start playing when ready. To disable this behaviour use add(item:playWhenReady:) and pass in false. This is true by default. To get notified of events during playback and loading, implement AudioPlayerDelegate and the player will notify you with changes.

If you want a simpler audio player without queue functionality, use:

let player = SimpleAudioPlayer()
let audioItem = DefaultAudioItem(audioUrl: "someUrl", sourceType: .stream)
player.load(item: audioItem)

NOTE: Do not use AudioPlayer directly. Use one of the above types.


The AudioPlayer has a state property, to make it easier to determine appropriate actions. The different states:

  • idle: The player is doing nothing, no item is set as current. This is the default state.
  • ready: The player has its current item set and is ready to start loading for playback. This is when you can call play() if you supplied playWhenReady=false when calling load(item:playWhenReady).
  • loading: The player is loading the track and will start playback soon.
  • playing: The player is playing.
  • paused: The player is paused.


The QueuedAudioPlayer maintains a queue of audio tracks.
The arrangement of the tracks are: [Previous]-[Current]-[Next].

When a track is done playing, the player will load the next track and update the queue, as long as automaticallyPlayNextSong is true (This is by default).

Items can be added to the queue by calling player.add(item:) or player.add(items:).
Use removeItem(atIndex:) and moveItem(fromIndex:toIndex:) to manipulate the queue.

The queue can be navigated by using next(), previous() and jumpToItem(atIndex:)

Audio Session

Remember to activate an audio session with an appropriate category for your app. This can be done with AudioSessionCategory:

try? AudioSessionController.set(category: .playback)
// You should wait with activating the session until you actually start playback of audio.
// This is to avoid interrupting other audio without the need to do it.
try? AudioSessionController.activateSession()

If you want audio to continue playing when the app is inactive, remember to activate background audio:
App Settings -> Capabilities -> Background Modes -> Check ‘Audio, AirPlay, and Picture in Picture’.

Now Playing Info

The AudioPlayer will automatically update the MPNowPlayingInfoCenter with artist, title, album, artwork, time if the passed in AudioItem supports this.
If you need to set additional properties for some items use AudioPlayer.add(property:). Available properties can be found in NowPlayingInfoProperty.

Remote Commands

The player will handle remote commands received from MPRemoteCommandCenter‘s shared instance, enabled by:

audioPlayer.remoteCommands = [
    .skipForward(intervals: [30]),
    .skipBackward(intervals: [30]),

These commands will be activated for each AudioItem. If you need some audio items to have different commands, implement RemoteCommandable. These commands will override the commands found in AudioPlayer.remoteCommands so make sure to supply all commands you need for that particular AudioItem.

Remember to go to App Settings -> Capabilites -> Background Modes -> Check ‘Remote notifications’


Currently some configuration options are supported:

  • automaticallyWaitsToMinimizeStalling: Whether the player should delay playback start to minimize stalling. If you are streaming large audio files and playback start is slow, it can help to set this to false. Default is true.
  • bufferDuration: The amount of seconds to be buffered by the player. Does not have any effect if automaticallyWaitsToMinimizeStalling is set to true.
  • timeEventFrequency: This decides how ofen the delegate should be notified that a time unit elapsed in the playback.
  • volume: The volume of the player. From 0.0 to 1.0.
  • automaticallyUpdateNowPlayingInfo: If you want to handle updating of the MPNowPlayingInfoCenter yourself, set this to false. Default is true.
