Losing image orientation while converting an image to CGImage

Question

I\'m facing an image orientation issue when cropping a square portion of an image out of a rectangular original image. When image is in landscape, it\'s fine. But when it is

SWIFT 5. I added the following as an extension to UIImage. Idea is to force the image inside you UIImage to match that of the UIImage orientation (which only plays a role in how it's displayed on the UI!). Redrawing the actual image data inside the UIImage "container" will make the corresponding CGImage has the same orientation

func forceSameOrientation() -> UIImage {
    UIGraphicsBeginImageContext(self.size)
    self.draw(in: CGRect(origin: CGPoint.zero, size: self.size))
    guard let image = UIGraphicsGetImageFromCurrentImageContext() else {
        UIGraphicsEndImageContext()
        return self
    }
    UIGraphicsEndImageContext()
    return image
}
