Uploading recording to Firebase with Swift - ios

Question

I've been trying to upload audio recording right after user stops recording to the Firebase. But it doesn't do anything apart from creating a new folder named "audio".
Code I'm using for starting and stopping recording
#IBAction func recordAudio(_ sender: AnyObject) {
recordingLabel.text = "Recording in progress"
stopRecordingButton.isEnabled = true
recordButton.isEnabled = false
let dirPath = NSSearchPathForDirectoriesInDomains(.documentDirectory,.userDomainMask, true)[0] as String
let recordingName = "recordedVoice.wav"
let pathArray = [dirPath, recordingName]
let filePath = URL(string: pathArray.joined(separator: "/"))
let session = AVAudioSession.sharedInstance()
try! session.setCategory(AVAudioSessionCategoryPlayAndRecord, with:AVAudioSessionCategoryOptions.defaultToSpeaker)
try! audioRecorder = AVAudioRecorder(url: filePath!, settings: [:])
audioRecorder.delegate = self
audioRecorder.isMeteringEnabled = true
audioRecorder.prepareToRecord()
audioRecorder.record()
}
#IBAction func stopRecording(_ sender: AnyObject) {
print("Stop recording button was pressed")
recordButton.isEnabled = true
stopRecordingButton.isEnabled = false
recordingLabel.text = "Tap to Record"
audioRecorder.stop()
let audioSession = AVAudioSession.sharedInstance()
try! audioSession.setActive(false)
}
code I'm using for uploading to Firebase
func audioRecorderDidFinishRecording(_ recorder: AVAudioRecorder, successfully flag: Bool) {
print("finished recording")
let storageRef = Storage.storage().reference().child("audio/recordedVoice.wav")
if let uploadData = AVFileType(self.recordedVoice.wav!) {
storageRef.put(uploadData, metadata: nil) {(metadata, error) in
if error != nil {
print(error)
return
}
}
}
}
Please help me!

Answer 1

Try:
let audioName = NSUUID().uuidString //You'll get unique audioFile name
let storageRef = Storage.storage().reference().child("audio").child(audioName)
let metadata = StorageMetadata()
metadata.contentType = "audio/wav"
if let uploadData = AVFileType(self.recordedVoice.wav!) {
storageRef.putData(uploadData, metadata: metadata) { (metadata, err) in
if err != nil {
//print(err)
return
}
if let _ = metadata?.downloadURL()?.absoluteString {
print("uploading done!")
}
}
}

so I have been working on this for hours and here is my answer:
func getDocumentsDirectory() -> URL {
let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
return paths[0]
}
func getFileURL() -> URL {
let path = getDocumentsDirectory()
let filePath = path.appendingPathComponent(K.fileName)
return filePath
}
let referance = storage.reference()
let mediaFolder = referance.child("media")
let id = UUID().uuidString // using uuid to give uniq names to audiofiles preventing overwrite
let mediaRef = mediaFolder.child(id + K.fileName) // creating file referance using uuid + filename
let path = getFileURL() // getting filepath
do {
let data = try Data(contentsOf: path) // getting data from filepath
mediaRef.putData(data) { metadata, error in
if error != nil {
self.showAlert(title: "Error", message: error?.localizedDescription, cancelButtonTitle: "cancel", handler: nil)
} else {
mediaRef.downloadURL { url, error in
let url = url?.absoluteString
print(url)
}
}
}
print("record has come")
} catch {
print("error cant get audio file")
}
I'm relatively new at coding and still learning. So that my answer may not be the best and shortest. But This worked for me.
