I made several tests: the issue is that neither the text nor the image are shown to bother for the callback function!At any rate openCamera is in the main class, otherwise the compliler would not even compile.

Nope: I also tried to insert the picker in the main class by putting the callback in an extensione with exactly the same result: I both opened a bug report and a TSI. I hope someone shall take care:extension ViewController: UIImagePickerControllerDelegate, UINavigationControllerDelegate{
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
picker.dismiss(animated: true, completion:{
self.maySubmit=true
})
cancelImageCallback?()
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
self.dismiss(animated: true, completion: nil)
var finalImage: UIImage?
if let image = info[.livePhoto] as? UIImage {
finalImage=image
} else if let image = info[.editedImage] as? UIImage {
finalImage=image
} else if let image = info[.originalImage] as? UIImage {
finalImage=image
}
pickImageCallback?(finalImage)
picker.dismiss(animated: true, completion: {
self.maySubmit=true
})
}
func navigationController(_ navigationController: UINavigationController, didShow viewController: UIViewController, animated: Bool) {
print("navigation will show")
let bar = navigationController.navigationBar
bar.isHidden=false
if let barItem=bar.topItem {
let camera = UIBarButtonItem(title: "camera", style: .plain, target:self, action: #selector(openCamera))
barItem.rightBarButtonItem=camera
let dismiss = UIBarButtonItem(barButtonSystemItem: .cancel, target: self, action: #selector(cancel))
barItem.leftBarButtonItem=dismiss
}
}
}

As you may see, in my code I had:func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool)changing it to:func navigationController(_ navigationController: UINavigationController, didShow viewController: UIViewController, animated: Bool)changes absolutely nothing.At any rate I tried virtually anything: NavigationController, ViewController, self, picker...

At any rate I changed the code to the following, given presenting a view controller over another view controller was not a great idea:import UIKit
class PickerViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate{
var pickImageCallback : ((UIImage?) -> ())?
var cancelImageCallback : (() -> Void)?
var cameraView: UIView!
var cameraButton:UIButton!
var picker: UIImagePickerController!
override func viewDidLoad() {
super.viewDidLoad()
picker=UIImagePickerController()
picker.delegate=self
picker.sourceType = .photoLibrary
self.add(asChildViewController: picker)
}
func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {
print("m in")
viewController.navigationItem.title = "Home"
let camera = UIBarButtonItem(title: "camera", style: .plain, target:self, action: #selector(openCamera))
viewController.navigationItem.leftBarButtonItem = camera
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
//self.navigationItem.leftBarButtonItem=UIBarButtonItem(image: UIImage(named:"camera"), style: .plain, target: self, action: #selector(openCamera))
//self.cameraView=UIView(frame: CGRect(x: 0, y: 0, width: self.view.frame.width, height: 40))
//self.cameraView.backgroundColor=UIColor.clear
//cameraButton=UIButton(frame: CGRect(x: 60, y: 12, width: 50, height: 35))
//cameraButton.setBackgroundImage(UIImage(named:"camera"), for: .normal)
//cameraButton.reversesTitleShadowWhenHighlighted=true
//cameraButton.addTarget(self, action: #selector(openCamera), for: .touchUpInside)
//self.cameraView.addSubview(cameraButton)
//self.view.addSubview(cameraView)
}
private func add(asChildViewController viewController: UIViewController) {
// Add Child View Controller
addChild(viewController)
// Add Child View as Subview
view.addSubview(viewController.view)
// Configure Child View
viewController.view.frame = view.bounds
viewController.view.autoresizingMask = [.flexibleWidth, .flexibleHeight]
// Notify Child View Controller
viewController.didMove(toParent: self)
viewController.navigationItem.leftBarButtonItem=UIBarButtonItem(image: UIImage(named:"camera"), style: .plain, target: self, action: #selector(openCamera))
}
@objc func openCamera(){
if(UIImagePickerController.isSourceTypeAvailable(.camera)){
let picker=UIImagePickerController()
picker.delegate=self
picker.sourceType = .camera
picker.showsCameraControls=true
self.add(asChildViewController: picker)
} else {
let title=NSLocalizedString("Warning", comment:"")
let message=NSLocalizedString("You don't have camera", comment:"")
let dismiss=NSLocalizedString("Dismiss", comment:"")
let alertController = UIAlertController(title: title, message: message, preferredStyle: .alert)
let cancelAction = UIAlertAction(title: dismiss, style: .cancel) { (action) in
}
alertController.addAction(cancelAction)
if let viewController=UIApplication.topViewController() as? ViewController{
viewController.proxyPresentViewController(alertController, animated: true, completion: nil)
}
}
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
cancelImageCallback?()
self.dismiss(animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
self.dismiss(animated: true, completion: nil)
var finalImage: UIImage?
if let image = info[.livePhoto] as? UIImage {
finalImage=image
} else if let image = info[.editedImage] as? UIImage {
finalImage=image
} else if let image = info[.originalImage] as? UIImage {
finalImage=image
}
pickImageCallback?(finalImage)
self.dismiss(animated: true, completion: nil)
}
}

On my part I get: An error occurred while preparing the installation. Try running this application again. While I try to install Catalina after pushing reboot. I tried checking the date an rebooting and reinstalling several times to no effect. Moreover nothing appears in the profile pane, notwithstanding I also downloaded the beta profile for Catalina several times.
