Play audio file and save to document directory in iOS (Swift)

Play audio , save in document directory.

Some time we need to play a songs in application by using URL or pre save audio file. for this we need to follow some steps:

Steps are :

1: Avaudio player provides this facility;

Declare AVaudio player

import UIKit
import AVFoundation
var audioPlayer:AVAudioPlayer!


class ViewController: UIViewController{

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        let url = Bundle.main.url(forResource: "music", withExtension: "mp3")!
        do {
            audioPlayer = try AVAudioPlayer(contentsOf: url)
            guard let player = audioPlayer else { return }
            
            player.prepareToPlay()
        } catch let error {
            print(error.localizedDescription)
        }

    }

import UIKit

import AVFoundation

var audioPlayer:AVAudioPlayer!

class ViewController: UIViewController{

override func viewDidLoad() {

super.viewDidLoad()

// Do any additional setup after loading the view, typically from a nib.

let url = Bundle.main.url(forResource: "music", withExtension: "mp3")!

do {

audioPlayer = try AVAudioPlayer(contentsOf: url)

guard let player = audioPlayer else { return }

player.prepareToPlay()

} catch let error {

print(error.localizedDescription)

}

Note: here “music ” is local store mp3 file .

2: by using URL:

for this we need to first download and play.

@IBAction func downloadFile(_ sender: Any) {
        
        if let audioUrl = URL(string: "http://freetone.org/ring/stan/iPhone_5-Alarm.mp3") {
            
            // then lets create your document folder url
            let documentsDirectoryURL =  FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
            
            // lets create your destination file url
            let destinationUrl = documentsDirectoryURL.appendingPathComponent(audioUrl.lastPathComponent)
            print(destinationUrl)
            
            // to check if it exists before downloading it
            if FileManager.default.fileExists(atPath: destinationUrl.path) {
                print("The file already exists at path")
                
                // if the file doesn't exist
            } else {
                
                // you can use NSURLSession.sharedSession to download the data asynchronously
                URLSession.shared.downloadTask(with: audioUrl, completionHandler: { (location, response, error) -> Void in
                    guard let location = location, error == nil else { return }
                    do {
                        // after downloading your file you need to move it to your destination url
                        try FileManager.default.moveItem(at: location, to: destinationUrl)
                        print("File moved to documents folder")
                    } catch let error as NSError {
                        print(error.localizedDescription)
                    }
                }).resume()
            }
        }
        
    }

@IBAction func downloadFile(_ sender: Any) {

if let audioUrl = URL(string: "http://freetone.org/ring/stan/iPhone_5-Alarm.mp3") {

// then lets create your document folder url

let documentsDirectoryURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!

// lets create your destination file url

let destinationUrl = documentsDirectoryURL.appendingPathComponent(audioUrl.lastPathComponent)

print(destinationUrl)

// to check if it exists before downloading it

if FileManager.default.fileExists(atPath: destinationUrl.path) {

print("The file already exists at path")

// if the file doesn't exist

} else {

// you can use NSURLSession.sharedSession to download the data asynchronously

URLSession.shared.downloadTask(with: audioUrl, completionHandler: { (location, response, error) -> Void in

guard let location = location, error == nil else { return }

do {

// after downloading your file you need to move it to your destination url

try FileManager.default.moveItem(at: location, to: destinationUrl)

print("File moved to documents folder")

} catch let error as NSError {

print(error.localizedDescription)

}

}).resume()

}

3: For access the downloaded file and again play.

@IBAction func playdownload(_ sender: Any) {
        
        if let audioUrl = URL(string: "http://freetone.org/ring/stan/iPhone_5-Alarm.mp3") {
            
            // then lets create your document folder url
            let documentsDirectoryURL =  FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
            
            // lets create your destination file url
            let destinationUrl = documentsDirectoryURL.appendingPathComponent(audioUrl.lastPathComponent)

        //let url = Bundle.main.url(forResource: destinationUrl, withExtension: "mp3")!
        
        do {
            audioPlayer = try AVAudioPlayer(contentsOf: destinationUrl)
            guard let player = audioPlayer else { return }
            
            player.prepareToPlay()
            player.play()
        } catch let error {
            print(error.localizedDescription)
        }
        }
        
    }

@IBAction func playdownload(_ sender: Any) {

if let audioUrl = URL(string: "http://freetone.org/ring/stan/iPhone_5-Alarm.mp3") {

// then lets create your document folder url

let documentsDirectoryURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!

// lets create your destination file url

let destinationUrl = documentsDirectoryURL.appendingPathComponent(audioUrl.lastPathComponent)

//let url = Bundle.main.url(forResource: destinationUrl, withExtension: "mp3")!

do {

audioPlayer = try AVAudioPlayer(contentsOf: destinationUrl)

guard let player = audioPlayer else { return }

player.prepareToPlay()

player.play()

} catch let error {

print(error.localizedDescription)

}

4: you can also perform play and pause command .

  @IBAction func play(_ sender: Any) {
        
        
       if  audioPlayer.isPlaying{
           audioPlayer.pause()
       }else{
        audioPlayer.play()
        }
        
            
            
       
        
    }

@IBAction func play(_ sender: Any) {

if audioPlayer.isPlaying{

audioPlayer.pause()

}else{

audioPlayer.play()

}
