I'm trying play simple .wav file in my application.
Here is the code:
func alarmSound() {
var player: AVAudioPlayer?
guard let path = Bundle.main.path(forResource: "emergency021", ofType: "wav") else {
print("Can't find audio file")
return
}
let url = URL(fileURLWithPath: path)
do {
player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileType.wav.rawValue)
if let prepare = player?.prepareToPlay() {
print("Player prepared: \(prepare)")
}
player?.volume = 1.0
player?.play()
} catch {
print("Playing sound error: \(error)")
}
}
Everything ok, file in the bundle, url is ok, player prepared, but.. there is no any sound. I have tried .mp3 file - same result.
Any ideas, why?
Issue was declaring player: AVAudioPlayer locally in function body, when I moved it up to ViewController all works.

I want to play a sound after each network request is successful. I have some objects that I want to send to the server using a for loop. In each iteration I'm sending a request to the server and after each request is complete, I want to play a sound.
I've tried this:
for object in objects {
sendObjectToServer(object)
}
func playSound() {
let url = Bundle.main.url(forResource: "sound", withExtension: "mp3")!
let player = try! AVAudioPlayer(url)
player.play()
}
func sendObjectToServer(object: Object) {
URLSession.shared.dataTask(with url: object.url) {(data,response,error) in
DispatchQueue.main.async {
playSound() // doesn't play sound synchronously
}
}
}
Why are you using the main thread for background-related operations. Only update your UI in the Dispatch.main.async code:
Try this on a physical device (tested and worked)
import AVFoundation
for object in objects {
DispatchQueue.global(qos: .background).async {
sendObjectToServer(object)
}
}
var player: AVAudioPlayer?
func playSound() {
guard let url = Bundle.main.url(forResource: "sound", withExtension: "mp3") else { return }
do {
try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default)
try AVAudioSession.sharedInstance().setActive(true)
/* The following line is required for the player to work on iOS 11. Change the file type accordingly*/
player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileType.mp3.rawValue)
/* iOS 10 and earlier require the following line:
player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileTypeMPEGLayer3) */
guard let player = player else { return }
player.play()
} catch let error {
print(error.localizedDescription)
}
}
func sendObjectToServer(object: Object) {
URLSession.shared.dataTask(with url: object.url) {(data,response,error) in
// Custom Logic
playSound()
}
}
I have a struct with my audio player in it:
struct MT_Audio {
func playAudio(_ fileName:String, _ fileExtension:String, _ atVolume:Float) {
var audioPlayer = AVAudioPlayer()
if let audioPath = Bundle.main.path(forResource: fileName, ofType: fileExtension) {
let audioURL = URL(string:audioPath)
do {
audioPlayer = try AVAudioPlayer(contentsOf: audioURL!)
audioPlayer.volume = atVolume
audioPlayer.prepareToPlay()
audioPlayer.play()
} catch {
print(error)
}
}
}
}
//I'm calling it in viewDidLoad like this:
guard let fileURL = Bundle.main.url(forResource:"heartbeat-01a", withExtension: "mp3")
else {
print("can't find file")
return
}
let myAudioPlayer = MT_Audio() //<--RESOLVED THE ISSUE BY MAKING THIS A PROPERTY OF THE VIEWCONTROLLER
myAudioPlayer.playAudio("heartbeat-01a", "mp3", 1.0)
Since it doesn't crash and burn on the guard I know the file is there. I've also put a break point in after the try and I am getting to the audio player. When I go to the actual file and click on it in Xcode it plays. This fails on both the sim and device. Any help would be appreciated.
Looks like your audioPlayer is only stored within your playAudio function.
Try to keep the audioPlayer as an variable inside your class like this:
struct MT_Audio {
var audioPlayer: AVAudioPlayer?
mutating func playAudio(_ fileName:String, _ fileExtension:String, _ atVolume:Float) {
// is now member of your struct -> var audioPlayer = AVAudioPlayer()
if let audioPath = Bundle.main.path(forResource: fileName, ofType: fileExtension) {
let audioURL = URL(string:audioPath)
do {
let audioPlayer = try AVAudioPlayer(contentsOf: audioURL!)
audioPlayer.volume = atVolume
audioPlayer.prepareToPlay()
audioPlayer.play()
} catch {
print(error)
}
}
}
}
I have been trying to make a game to teach myself swift, and cant seem to get this code to work. I am extremely new to this, and can't seem to find out why it won't work... XCode doesn't flag any problems, build sucseed, and debugger even prints "Got to Stage 1 & Got to Stage 2... anything help?
I Imported AVFoundation..
class GAME {
class func SuperStartGame(playerwhowon1: SKSpriteNode) {
var player = AVAudioPlayer()
func PlaySound() {
guard let URL = Bundle.main.url(forResource: "PowerUp", withExtension: "mp3")
else {
print("Didn't Find URL")
return
}
do {
print("Got to Stage 1")
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
try AVAudioSession.sharedInstance().setActive(true)
player = try AVAudioPlayer(contentsOf: URL, fileTypeHint: "mp3")
player.prepareToPlay()
player.play()
print("Got to Stage 2")
} catch let error as NSError {
print("error: \(error.localizedDescription)")
}
RoundNumber += 1
Round.text = "Round \(RoundNumber)"
if playerwhowon1 == Mine {
MyScore.run(addscoreM) {
PlaySound()
Round.run(NewRoundForRound) {
...
Code keeps going.. thats the only part that is relevant to the sound. I added the sound file to Xcode, and made sure it was added tot he project target... it is in my main bundle.
Make sure that your device isn't muted
mp3 file is copied to bundle
Example VC playing sound:
class ViewController: UIViewController {
var game = Game()
#IBAction func playAction(_ sender: UIButton) {
game.playSound()
}
}
class Game {
var player: AVAudioPlayer?
func playSound() {
guard let URL = Bundle.main.url(forResource: "SampleAudio", withExtension: "mp3") else {
print("Didn't Find URL")
return
}
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
try AVAudioSession.sharedInstance().setActive(true)
player = try AVAudioPlayer(contentsOf: URL, fileTypeHint: "mp3")
player?.prepareToPlay()
player?.play()
} catch let error as NSError {
print("\(error.localizedDescription)")
}
}
}
I have a code in Swift which plays a bird game. A bird collects eggs. I want to play a coin sound upon bird touching the egg. I tried code below but it's not playing upon contact. How can I accomplish it?
do {
// Preperation
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
} catch _ {
}
do {
try AVAudioSession.sharedInstance().setActive(true)
} catch _ {
}
// Play the sound
do {
audioPlayer = try AVAudioPlayer(contentsOfURL: alertSound)
} catch _{
}
audioPlayer.prepareToPlay()
audioPlayer.play()
Create a path to the sound file
let path = NSBundle.mainBundle().pathForResource("(sound name)", ofType: (type) )!
Url for the path
var url = NSURL()
Variable to hold sound
var soundEffect: AVAudioPlayer!
Then when you want to play the sound
url = NSURL(fileURLWithPath: path)
do {
let sound = try AVAudioPlayer(contentsOfURL: url)
soundEffect = sound
sound.play()
} catch {
}
Hi I am trying to play a music file with a following code in swift 2. Basically I just dragged the audio file with a name f.mp3 to the asses folder and it my code breaks with the following message:
unexpectedly found nil while unwrapping an Optional value. Where exactly I need to put my mp3 file so the IOS can find it. Thank you
var audioPlayer: AVAudioPlayer! = nil
func playMyFile() {
let path = NSBundle.mainBundle().pathForResource("f", ofType: "mp3")
let fileURL = NSURL(fileURLWithPath: path)
do {
try audioPlayer = AVAudioPlayer(contentsOfURL: fileURL)
} catch {
print("error")
}
audioPlayer.prepareToPlay()
audioPlayer.delegate = self
audioPlayer.play()
}
Your code is working fine with my project and here is my complete code:
import UIKit
import AVFoundation
class ViewController: UIViewController {
var audioPlayer: AVAudioPlayer! = nil
override func viewDidLoad() {
super.viewDidLoad()
playMyFile()
}
func playMyFile() {
let path = NSBundle.mainBundle().pathForResource("f", ofType: "mp3")
let fileURL = NSURL(fileURLWithPath: path!)
do {
try audioPlayer = AVAudioPlayer(contentsOfURL: fileURL)
} catch {
print("error")
}
audioPlayer.prepareToPlay()
audioPlayer.play()
}
}
Make sure your audio is added into Copy Bundle Resources like this:
If not added then add it this way:
