Find the location of an song in iPod library in swift?

Question

I have the reference of a MPMediaItem when user selects an audio from the iPod library. I am getting the asset url of that item by using

let url = item.valueForProperty(MPMediaItemPropertyAssetURL)But this is not giving me the exact physical location of the file, instead it is giving me an url w.r.t iPod library.

ipod-library://item/item.mp3?id=1840064795502796074

Is there a way to get the physical url of a song from iPod library?

EDIT - actually I want to extract NSData from the physical file and send it to my backend server, so i need the physical file URL and not the relative URL

You can't do that. The file is outside your app's sandbox so you can't access it directly. You can only ask the MPMediaPlayer to play it for you. — Paulw11

Music files are represented by MPMediaItem instances. You could use retrieve them through a MPMediaQuery, for example :

// All
let mediaItems = MPMediaQuery.songsQuery().items
// Or you can filter on various property
// Like the Genre for example here
var query = MPMediaQuery.songsQuery()
let predicateByGenre = MPMediaPropertyPredicate(value: "Rock", forProperty: MPMediaItemPropertyGenre)
query.filterPredicates = NSSet(object: predicateByGenre)

At this point, you have all (or some if you filter) 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.systemMusicPlayer()
player.setQueueWithItemCollection(mediaCollection)

player.play()

There is probably the possibility to access somehow the metadata (title, genre, artist, ...) from the songs.

This probably won't work on simulator.
