Xcode 11.1 Only Takes Square Photos - Need 4:3 - xcode

Question

I'm using the camera to capture images for an app. Once I touch the photo button, I am
only able to save the photo in a square format. I want to preserve the 4:3 format for
older cameras and eventually allow the user to choose 16:9 if desired. I have not been
able to find any code to programmatically chose aspect ratio. I only get square. I even
tried locking the Camera Mode in Camera Settings on the device. Thankfully, that
didn't work.
It is a SwiftUI app. In the CameraViewController below, if I remove the allowsEditing
option, the picker freezes - neither the Use Photo, nor Retake buttons function. The
app does not crash, just the view is frozen. I am able to swipe down the view to
dismiss and continue using the app.
I call the PhotoCaptureView below from a button in what would be the detail view of
a master/detail equivalent.
PhotoCaptureView:
import SwiftUI
struct PhotoCaptureView: View {
#EnvironmentObject var cameraSettings: CameraSettings
#Binding var photos: [UIImage]
var body: some View {
return VStack {
CameraViewController(photos: $photos)
.frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity)
}.edgesIgnoringSafeArea(.all)
}
}
And the model view CameraViewController:
import UIKit
import SwiftUI
import MobileCoreServices
import AVFoundation
struct CameraViewController: UIViewControllerRepresentable {
#EnvironmentObject var cameraSettings: CameraSettings
#Binding var photos: [UIImage]
func updateUIViewController(_ uiViewContyroller: UIImagePickerController, context: Context) {
//no code here
}
func makeUIViewController(context: UIViewControllerRepresentableContext<CameraViewController>) -> UIImagePickerController {
let vc = UIImagePickerController()
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerController.SourceType.camera) {
vc.sourceType = .camera
vc.allowsEditing = true
vc.delegate = context.coordinator
return vc
}
return UIImagePickerController()
}
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
class Coordinator: NSObject, UINavigationControllerDelegate, UIImagePickerControllerDelegate {
var parent: CameraViewController
init(_ imagePickerController: CameraViewController) {
self.parent = imagePickerController
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
guard let image = info[.editedImage] as? UIImage else {
print("no image found")
return
}
print("Image taken successfully, with size \(image.size)")
parent.photos.append(image)
picker.dismiss(animated: true) {
print("in dismiss after successful picture")
}
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
picker.dismiss(animated: true) {
print("in did cancel")
}
}
private func pickerController(_ controller: UIImagePickerController, didSelect image: UIImage?) {
controller.dismiss(animated: true, completion: nil)
}
}
}
The CameraSettings are just Bools to determine whether to present the camera option.
class CameraSettings: ObservableObject {
#Published var isAuthorized: Bool = false
#Published var isCameraAvailable: Bool = false
}
Xcode 11.1 (11A1027) I am using an iPhone X iOS 13.1.2
Any guidance would be appreciated.

The info setting of didFinishPickingMediaWithInfo needs to specify "originalImage" to avoid the square only picture. Even with the edited version, however, it seems you can only move the image around - not change the aspect.
change the info line above to:
guard let image = info[.originalImage] as? UIImage else {
Then set:
vc.allowsEditing = false
Importantly the documentation tells me that: "The UIImagePickerController class supports portrait mode only."
