Can I use AVCaptureDevicePosition to toggle between front and back camera inputs?

Is it as easy as:

-(IBAction)switchCameraTapped: (id)sender{
if (AVCaptureDevicePosition == 1) {
    AVCaptureDevicePosition == 2;
} else if (AVCaptureDevicePosition ==2){
    AVCaptureDevicePosition == 1;}
}

?

Do I have to create a new capture session or remove any existing inputs?

No, it's not that simple - the position is a read-only property on AVCaptureDevice:

@property(nonatomic, readonly) AVCaptureDevicePosition position;

You don't need to destroy the capture session, you can instead call

[session stopRunning];

and reconfigure the inputs with removeInput and addInput.

Don't forget to call startRunning when you've finished.
