My scenario, I am trying to create audio record and save file into iPhone documentdirectory.

I have done recording functionality but I need to implement save file name based on user input. After audio record, If user click save button I am asking file name to user by alertviewcontroller with textfield.

Here, my audio file saving by static file name(audio.m4a) because inside viewdidload I implemented save document directory code but I dont know how to implement save file name based on user input within save action.

override func viewDidLoad() {

  super.viewDidLoad() 

  let session = AVAudioSession.sharedInstance()

        try? session.setCategory(AVAudioSessionCategoryPlayAndRecord)

        try? session.overrideOutputAudioPort(.speaker)

        try? session.setActive(true)

        if let basePath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first {

            let baseComponents = [basePath,"audio.m4a"]

            if let audioURL = NSURL.fileURL(withPathComponents: baseComponents) {

                var settings: [String: Any] = [:]

                self.audioURL = audioURL

                settings[AVFormatIDKey] = Int(kAudioFormatMPEG4AAC)

                settings[AVSampleRateKey] = 44100.0

                settings[AVNumberOfChannelsKey] = 2

                audioRecorder = try? AVAudioRecorder(url: audioURL, settings: settings)

                audioRecorder?.prepareToRecord()

            }

        }

}



@IBAction func record_click(_ sender: Any) {

        if let audioRecorder = self.audioRecorder {

            if (audioRecorder.isRecording) {

                audioRecorder.stop()

           } else {

                audioRecorder.record()

            }

        }

    }



// Within below action I am calling alertview with textfield for asking file name

@IBAction func save_click(_ sender: Any) {

   self.savefileAlertView()

}

If you want to set name of file which has been already saved you can rename it.

You can create this function

func renameAudio(newTitle: String) {

    do {

        let path = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]

        let documentDirectory = URL(fileURLWithPath: path)

        let originPath = documentDirectory.appendingPathComponent("audio.m4a")

        let destinationPath = documentDirectory.appendingPathComponent("(newTitle).m4a")

        try FileManager.default.moveItem(at: originPath, to: destinationPath)

    } catch {

        print(error)

    }

}

And in your alert controller use it and as parameter pass text of text field inside alert.
