Recording

The first scene was created to let the user choose the video that he/she wanted to edit. Now, we have to create another scene where the user will watch the movie while recording his/her narrative over it.

Add a new file called RecorderViewController.swift to your project and import UIKit, AVFoundation, and Photos, as shown in the following code:

import UIKit
import AVFoundation
import Photos

Create a class called RecorderViewController, which inherits from UIViewController and implements the AVAudioRecorderDelegate protocol with the following code:

class RecorderViewController: UIViewController, AVAudioRecorderDelegate {

This scene will have only a view, where the user will watch the movie, and a button to record the audio. Based on this information, we are going to add UIView and UIButton as attributes. Place the following code to add the needed UI attributes:

    @IBOutlet weak var videoView: UIView!
    @IBOutlet weak var recordButton: UIButton!

This class still needs more attributes...
