let imageManager = PHImageManager.default()
var photo : PHAsset
var options : PHImagerequestOptions

imageManager.requestImageData(for: photo,options: options,resultHandler: {
                imageData,dataUTI,orientation,info in
let ciImage = CIImage(data: imageData!)
if #available(iOS 10.0,*) {
    data = CIContext().jpegRepresentation(of: ciImage!,colorSpace: CGColorSpaceCreateDeviceRGB())!
    // upload image data
}
