Type 'AVCaptureDevice' has no member 'defaultDevice'

Question

Working on a QR code reader. I am new to programming so this might be an easy fix. The error is "Type 'AVCaptureDevice' has no member 'defaultDevice'" Thanks for the help in advance!

 //Creating session
    let session = AVCaptureSession()
    //Define capture device
    let captureDevice = AVCaptureDevice.defaultDevice(withMediaType: AVMediaTypeVideo)

    do
    {
        let input = try AVCaptureDeviceInput(device: captureDevice)
        session.addInput(input)
    }

Answer 1

You are using the old Swift 2 API. The line:

let captureDevice = AVCaptureDevice.defaultDevice(withMediaType: AVMediaTypeVideo)

should be:

let captureDevice = AVCaptureDevice.default(for: .video)

Answer 2

This is swift 3.0

let captureDevice = AVCaptureDevice.defaultDevice(withMediaType: AVMediaTypeVideo)

In swift 4.1

AVCaptureDevice.default(for: AVMediaType.video)
{
   let input = AVCaptureDeviceInput(device: captureDevice)
   session.addInput(input)
}

I hope this will help you
