// Do any additional setup after loading the view, typically from a nib.

Here's my stripped working code. I use two pickers - one for camera, one for library - because of some odd iOS bug with tint color. To avoid "massive view controller" issues, I tend to move everything possible related to a a UIImagePickerController into a separate file and extension.

UIImagePickerController

class OpenViewController: UIViewController

let pickerLibrary = UIImagePickerController()
override func viewDidLoad()
super.viewDidLoad()
pickerLibrary.delegate = self




extension OpenViewController: UIImagePickerControllerDelegate, UINavigationControllerDelegate

@objc func showImagePicker()
pickerLibrary.allowsEditing = false
pickerLibrary.sourceType = .photoLibrary
present(pickerLibrary,
animated: true,
completion: nil)
pickerLibrary.popoverPresentationController?.sourceView = self.view

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
let selectedImage = info[UIImagePickerControllerOriginalImage] as! UIImage
dismiss(animated: true, completion: nil)

func imagePickerControllerDidCancel(_ picker: UIImagePickerController)
dismiss(animated: false, completion: nil)




While the present code looks correct, I notice several things you didn't post in your code. Maybe because you just didn't post it, but I would definitely check these things:

present

ViewController

ViewController.view

UIImagePickerControllerDelegate, UINavigationControllerDelegate

Now as your error suggests, something else is likely the issue - a UIViewController can present another view controller. In this case you've given us no way to duplicate that error. In other words, I'm assuming that (1) You are seeing a UIButton attached to Alert() - BTW, Swift conventions use lower case for that - and (2) You've proven that when that button is tapped, `Alert() is actually executed.

UIViewController

present

UIButton

Alert()
