Answer 1

Please try this one.

func rotateImage(image: UIImage) -> UIImage? {
        if (image.imageOrientation == UIImage.Orientation.up ) {
            return image
        }
        UIGraphicsBeginImageContext(image.size)
        image.draw(in: CGRect(origin: CGPoint.zero, size: image.size))
        let copy = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return copy
    }

Happy Codding :)
