Pass Captured/Gallery Image from one ViewController to another - swift

Question

I want to capture a photo or pick it from the gallery and then pass it inside an imageView to another ViewController. I make the sequel successfully but I don't know how to pass the image from the imagePickerController.
First ViewController
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if let selectedImage = info[.originalImage] as? UIImage{
imagePicker.dismiss(animated: true){
self.performSegue(withIdentifier: "goToCropScreen", sender: self)
}
}
}
//Navigation to other screens
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "goToCropScreen"{
let destinationVC = segue.destination as! CropViewController
destinationVC.imageToCrop = //Here is the problem. Idont know what image to use.
}
}
Second ViewController
class CropViewController: UIViewController {
#IBOutlet weak var cropImageView: UIImageView!
var imageToCrop : UIImage?
override func viewDidLoad() {
super.viewDidLoad()
cropImageView.image = imageToCrop
}
}
I know that I can't use selectedImage because its inside the imagePickerController. Is there a way to use it like globally.

Answer 1

Create a variable in FirstViewController. And store the selected image in this variable and pass the value in prepare for segue method
class FirstViewController: UIViewController {
var selectedImage: UIImage?
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if let selectedImage = info[.originalImage] as? UIImage{
imagePicker.dismiss(animated: true){
self.selectedImage = selectedImage
self.performSegue(withIdentifier: "goToCropScreen", sender: self)
}
}
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "goToCropScreen"{
let destinationVC = segue.destination as! CropViewController
destinationVC.imageToCrop = self.selectedImage
}
}
}
