Is it possible to append Data of audio file in AVAudioPlayer?

Question

i'hv added 10 audio files (1.m4a,2.m4a,...,10.m4a) in my local project and i convert first part into data and append into NSMutableData then load in player. working good. Now i have button, onClick of button i append 3 parts of music files, but its now playing in avaudioplayer. Does anyone know how can i do this?

 func loadFirstnPlay() {
    if let url = Bundle.main.url(forResource: "1", withExtension: "m4a"){
        if let rawData = NSData(contentsOf: url) {
            arrSongsData.append(rawData as Data)
            do {
                avAudioPlyer = try AVAudioPlayer(data: arrSongsData as Data)
                avAudioPlyer.prepareToPlay()
                avAudioPlyer.delegate = self
                avAudioPlyer.play()
                print("Play")
            }catch{
                print("Error : ",error)
            }
        }
    }
}

onButtonClick

 func onButtonClick() {
    for i in 2...4{
        if let url = Bundle.main.url(forResource: "\(i)", withExtension: "m4a"){
            if let rawData = NSData(contentsOf: url) {
                arrSongsData.append(rawData as Data)
                print("\(i) : ",arrSongsData.length)
            }
        }
    }
}

@JayeshThanki yes, but if my previous track is playing then audio data need to append in currently playing Data — Pratik Prajapati, Feb 09 '18 at 09:27
@SemyonTikhonenko nop i use `Extended Audio File Services` to play queue songs, its suitable for my need. — Pratik Prajapati, Apr 26 '18 at 04:34

If you want to play audio one by one then you can also use AVQueuePlayer with AVPlayerItem.

var arrSongItem:[AVPlayerItem] = []
var avQueuePlayer:AVQueuePlayer!

func loadFirstnPlay() {
    for i in 1...10 {
        if let url = Bundle.main.url(forResource: "\(i)", withExtension: "m4a"){
            let item = AVPlayerItem.init(url: url)
            arrSongItem.append(item)
        }
    }
    avQueuePlayer = AVQueuePlayer(items: arrSongItem)
    avQueuePlayer.play()
}

You can also insert items, remove items and next the current item using AVQueuePlayer object.

yeah! but i want to append playing raw data, like queue. 1st track is playing then 2nd track need append, not play directly – Pratik Prajapati Feb 09 '18 at 09:29
you can this `insert(_:after:)` function to insert item dynamically in queue. – Jayesh Thanki Feb 09 '18 at 09:32
Thanks for replying, i know this, but my main goal is to append NSData in player not item. at the end its work like single file – Pratik Prajapati Feb 09 '18 at 09:45
so you have to merge audio files in one file and then you have to convert into `NSData` to play audio. – Jayesh Thanki Feb 09 '18 at 09:48
