How to unselect an image from Image Picker in SwiftUI - ios

Question

I am creating a message app with SwiftUI.
I have made an Image Picker to allow sending photos.
Here is the code of my Image Picker :
import SwiftUI
struct ImagePicker: UIViewControllerRepresentable {
#Binding var image: UIImage?
#Binding var didSet: Bool
private let controller = UIImagePickerController()
var sourceType: UIImagePickerController.SourceType = .photoLibrary
func makeCoordinator() -> Coordinator {
return Coordinator(parent: self)
}
class Coordinator: NSObject, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
let parent: ImagePicker
init(parent: ImagePicker) {
self.parent = parent
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
parent.image = info[.originalImage] as? UIImage
parent.didSet = true
picker.dismiss(animated: true)
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
picker.dismiss(animated: true)
}
}
func makeUIViewController(context: Context) -> some UIViewController {
controller.sourceType = sourceType
controller.allowsEditing = false
controller.delegate = context.coordinator
return controller
}
func updateUIViewController(_ uiViewController: UIViewControllerType, context: Context) {
}
}
When a picture is selected, it is shown in a view, so that, the user can see it before sending it.
I would like to implement a button that would unselect the image shown, but I don't know how to do it. I would like to know if there is a way to unselect the image.
Do you have any ideas ?
Thank you.
