Using ImageIO and Swift to convert a UIImage to Data

UIImageToDataIO.swift

func UIImageToDataIO(image: UIImage, compressionRatio: CGFloat, orientation: Int = 1) -> Data? {
    return autoreleasepool(invoking: { () -> Data in
        let data = NSMutableData()
        let options: NSDictionary = [
            kCGImagePropertyOrientation: orientation,
            kCGImagePropertyHasAlpha: true,
            kCGImageDestinationLossyCompressionQuality: compressionRatio
        ]
        
        let imageDestinationRef = CGImageDestinationCreateWithData(data as CFMutableData, kUTTypeJPEG, 1, nil)!
        CGImageDestinationAddImage(imageDestinationRef, image.cgImage!, options)
        CGImageDestinationFinalize(imageDestinationRef)
        return data as Data
    })
}
