IBOutet is not being recognized as an UIimage

I am trying to allow users to take photos when the button action is clicked. Ive added an UIImage into storyboard which has a UIImage linked to my View Controller.I’ve set the name for this image as imageView, yet when I implement imageView.image = image I am getting an error "Cannot find ‘imageView’ in scope" i’ve also tried to set this as self.imageView = image and I get the error "Cannot find self in scope". I am unsure why my imageView which is connected to the @IBOutlet is not being found?

    import UIKit

class HomeScreenViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {
     @IBOutlet weak var imageView: UIImageView!
     var button: UIButton! {
         imageView.backgroundColor = .secondarySystemBackground
        self.button.backgroundColor = .systemBlue
        
    }
    override func viewDidLoad() {
        super.viewDidLoad()
        
    }
    @IBAction func didTapButton(){
        let picker = UIImagePickerController()
        picker.sourceType = .camera
        picker.delegate = self
        present(picker, animated: true)
    }
}

func imagePickerControllerDidCancel(_ picker: UIImagePickerController){
    picker.dismiss(animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey: Any])      {
    picker.dismiss(animated: true, completion: nil)
    
    guard let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage  else {
        return
    }
    
    imageView.image = image
    
}

>Solution :

You function is not inside your class!! You should put inside it:

class HomeScreenViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey: Any]){
       // any code
    }
}
