How to use AVCapturePhotoOutput

Question

I have been working on using a custom camera, and I recently upgraded to Xcode 8 beta along with Swift 3. I originally had this:

var stillImageOutput: AVCapt         


        

Answer 1

The capture delegate function has been changed to photoOutput. Here's the updated function for Swift 4.

func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photoSampleBuffer: CMSampleBuffer?, previewPhoto previewPhotoSampleBuffer: CMSampleBuffer?, resolvedSettings: AVCaptureResolvedPhotoSettings, bracketSettings: AVCaptureBracketedStillImageSettings?, error: Error?) {            
        if let error = error {
            print(error.localizedDescription)
        }

        if let sampleBuffer = photoSampleBuffer, let previewBuffer = previewPhotoSampleBuffer, let dataImage = AVCapturePhotoOutput.jpegPhotoDataRepresentation(forJPEGSampleBuffer: sampleBuffer, previewPhotoSampleBuffer: previewBuffer) {
            print("image: \(String(describing: UIImage(data: dataImage)?.size))") // Your Image
        }
}
