Accessing front Camera with swift?
<p>I've done some searching and most answers are either in Obj-C or not applicable to this code.</p>

<p>I'm using this guide : <a href="http://drivecurrent.com/devops/using-swift-and-avfoundation-to-create-a-custom-camera-view-for-an-ios-app/" rel="nofollow">http://drivecurrent.com/devops/using-swift-and-avfoundation-to-create-a-custom-camera-view-for-an-ios-app/</a></p>

<p>and I've got this code from it: </p>

<pre><code>     super.viewWillAppear(animated)

    captureSession = AVCaptureSession()
    captureSession!.sessionPreset = AVCaptureSessionPresetPhoto

    let backCamera = AVCaptureDevice.defaultDeviceWithMediaType(AVMediaTypeVideo)
    let frontCamera = ????

    var error: NSError?
    var input: AVCaptureDeviceInput!
    do {
        input = try AVCaptureDeviceInput(device: backCamera)
    } catch let error1 as NSError {
        error = error1
        input = nil
    }
</code></pre>

<p>The back camera is the default but I'm not seeing how to straight up access the front camera in order to let people swap back and forth.</p>
