Value of type UIImage has no member cgImageOrientation - swift

Question

I am new coreml and I was reading a book I came across a code snippet and when I tried to run it I got the above error , I Googled but got no luck ,
here is my code
import UIKit
import Vision
extension UIImage {
func detectFaces(completion:#escaping ([VNFaceObservation]?)->()){
guard let image = self.cgImage else {
completion(nil)
return
}
let request = VNDetectFaceRectanglesRequest()
DispatchQueue.global().async {
let handler = VNImageRequestHandler(cgImage: image, orientation: self.cgImageOrientation)
//above error here I think cgImageOrientation is no longer available but what's the solution anyways
}
}
}
here I am using swiftUI and lifecycle methods are also selected as swiftui
,
The book name is "Practical Artificial intelligence with swift" by orielly

You need to continue working through the tutorial before you'll be able to compile it. The next section of the book talks about creating Views.swift, and step 8 of that section includes this extension:
extension UIImage {
func fixOrientation() -> UIImage? {
UIGraphicsBeginImageContext(self.size)
self.draw(at: .zero)
let newImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return newImage
}
var cgImageOrientation: CGImagePropertyOrientation {
switch self.imageOrientation {
case .up: return .up
case .down: return .down
case .left: return .left
case .right: return .right
case .upMirrored: return .upMirrored
case .downMirrored: return .downMirrored
case .leftMirrored: return .leftMirrored
case .rightMirrored: return .rightMirrored
}
}
}
