I am looking for a swift coding playing sound out of the player list and not sounds added as resource to your project.
I mainly found the usage of
NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("sound_name", ofType: "wav"))
println(alertSound)
but for this you need to have the sound file in your bundle. But I couldn't find any example
selecting audio files bought thru itunes and play them.
Any idea how to do this? Can I access my music layer playlist files and using them in my app?
Thanks for any code lines.

These music files are represented by MPMediaItem instances. To fetch them, you could use an MPMediaQuery, as follows:
let mediaItems = MPMediaQuery.songsQuery().items
At this point, you have all songs included in Music App Library, so you can play them with a MPMusicPlayerController after setting a playlist queue:
let mediaCollection = MPMediaItemCollection(items: mediaItems)
let player = MPMusicPlayerController.iPodMusicPlayer()
player.setQueueWithItemCollection(mediaCollection)
player.play()
You might need to filter songs by genre, artist, album and so on. In that case, you should apply a predicate to the query before fetching the media items:
var query = MPMediaQuery.songsQuery()
let predicateByGenre = MPMediaPropertyPredicate(value: "Rock", forProperty: MPMediaItemPropertyGenre)
query.filterPredicates = NSSet(object: predicateByGenre)
let mediaCollection = MPMediaItemCollection(items: query.items)
let player = MPMusicPlayerController.iPodMusicPlayer()
player.setQueueWithItemCollection(mediaCollection)
player.play()
Cheers!

When playing a video through AVPlayerViewController, its artist metadata does not show up in the player below the title in iOS control center / Lock Screen player.
Right now, I'm setting metadata to the AVPlayerItem itself in a function within an AVPlayerItem extension, along the lines of this:
func setMetadata(title: String, artist: String) {
let titleItem = AVMutableMetadataItem()
titleItem.identifier = AVMetadataIdentifier.commonIdentifierTitle
titleItem.value = title as (NSCopying & NSObjectProtocol)
self.externalMetadata.append(titleItem)
let artistItem = AVMutableMetadataItem()
artistItem.identifier = AVMetadataIdentifier.commonIdentifierArtist
artistItem.value = artist as (NSCopying & NSObjectProtocol)
self.externalMetadata.append(artistItem)
}
The title item works properly, but the artist is not updating. Any thoughts? Do videos have some other metadata field shown in the player that isn't artist?
I've tried .commonIdentifierDescription and .iTunesMetadataTrackSubtitle as alternate metadata identifiers but these are not working as expected.
I try to get file list from the Music Library (iPod Music Library), but I can't do it, my list is always empty. I sure that I have tracks in Music Library, I check it in other app - and it works. But as I remember that application sent me a request to access the Music Library. Perhaps I also need to create such a request? Help me solve the problem. I use this code to get file list:
func fetchFileList() {
let mediaItems = MPMediaQuery.songs().items
let mediaCollection = MPMediaItemCollection(items: mediaItems ?? [])
print("mediaCollectionItems: \(mediaCollection.items)") //It's always empty
//Then I'd like to get url of the track
//let item = mediaCollection.items[0]
//let pathURL = item.value(forProperty: MPMediaItemPropertyAssetURL) as? URL
//print("pathURL: \(pathURL)")
}
If you want to access the Music Library, you have to add NSAppleMusicUsageDescription key to your Info.plist with a description about what you want to do with the music.

I am trying to use an AVPlayer to play a video that has been recorded in my app. However, the player won't play the video. I know for a fact that this is a properly recorded mp4 file, because I can take it and play it on my Mac just fine. Here's the setup for the player:
let documents = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask).first!
let URL = NSURL(fileURLWithPath: "tempVideo", relativeToURL: documentsDirectory)
let asset = AVAsset(URL: URL)
let item = AVPlayerItem(asset: asset)
//videoPlayer is a property on the view controller being used
videoPlayer = AVPlayer()
//videoPlayerLayer is a property on the view controller being used
videoPlayerLayer = AVPlayerLayer(player: videoPlayer)
videoPlayerLayer.frame.size = view.frame.size
videoPlayerLayer.backgroundColor = UIColor.redColor().CGColor
view.layer.addSublayer(videoPlayerLayer!)
//wait 5 seconds
videoPlayer.play()
I know for sure that the videoPlayer is, in fact, ready to play, because I've checked its status property. I also know that videoPlayerLayer has properly been added to view.layer because its visible and takes up the whole screen. When I call videoPlayer.play(), the music playing on the device stops, but videoPlayerLayer doesn't show anything.
Any ideas? Thank you in advance for the help!
EDIT: I forgot to show that videoPlayerLayer is indeed connected to videoPlayer, I have updated my question to reflect this.
The correct answer was given by #Dershowitz123, but he or she left it in a comment so I can't mark it as correct. The solution was to change the URL to include the .mp4 extension. Thank you for your help.
I want to make a simple media player in Swift. I want to make a table with all Albums on the iphone and after selecting the album i want to play the songs of it. But i can not get the album titles (and artwork).
I tried:
var query = MPMediaQuery.albumsQuery()
let mediaCollection = MPMediaItemCollection(items: query.items)
println(mediaCollection.items)
let player = MPMusicPlayerController.systemMusicPlayer()
player.setQueueWithItemCollection(mediaCollection)
player.play()
MPMediaItem has valueForProperty() function. The properties which you need are MPMediaItemPropertyAlbumTitle and MPMediaItemPropertyArtwork.
I have uploaded few files on parse framework and I am live streaming those files and play them in AVPlayer.
let url = currentAudioPath
let playerItem = AVPlayerItem( URL:NSURL( string:url ) )
player1 = AVPlayer(playerItem:playerItem)
player1.rate = 1.0;
self.configurePlayer()
player1.play()
I have not downloaded the entire file at once. But is there a way to retrieve the length of the song?
"AVPlayerItem" has a ".duration" property that might help you.
Look at the notes though: You won't be able to get the duration "until the status of the AVPlayerItem is AVPlayerItemStatusReadyToPlay." You could also set a KVO on the property so you could update your UI once the item duration is determined by the AVFoundation layer.
