Swift 4 update:

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    let mediaType = info[UIImagePickerControllerMediaType] as! CFString
    let assetPath = info[UIImagePickerControllerReferenceURL] as! URL

    self.dismiss(animated: true, completion: nil)
    switch mediaType {
        case kUTTypeImage, kUTTypeLivePhoto, kUTTypeGIF:
            if let selectedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
                if (assetPath.absoluteString.hasSuffix("GIF")) || (assetPath.absoluteString.hasSuffix("gif")){
                    print("GIF")
                    let options = PHImageRequestOptions()

                    options.isNetworkAccessAllowed = false
                    options.deliveryMode = .highQualityFormat

                    guard let asset = PHAsset.fetchAssets(withALAssetURLs: [assetPath], options: nil).lastObject else { return }
                    PHImageManager.default().requestImageData(for: asset, options: options) { data, uti, orientation, info in
                    guard let info = info else { return }

                    if let error = info[PHImageErrorKey] as? Error {
                        print("Cannot fetch data for GIF image: \(error)")
                        return
                    }

                    if let isInCould = info[PHImageResultIsInCloudKey] as? Bool, isInCould {
                       print("Cannot fetch data from cloud. Option for network access not set.")
                        return
                    }
                    if let gifImageData = data {
                        // do something with data (it is a Data object)
                    }
                }
            } else {
                // this is the basic image 
            }
        }
        case kUTTypeMovie:
            if let videoURL = info[UIImagePickerControllerMediaURL] as? URL {
                // using video type
            }
        default:
            print("Others")
        }
    }
