Swift 4.2 imagePickerController issue

like this

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

In Swift 4.2 imagePickerController delegate methods has changed a bit. Kindly check out the below code.

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {

    var selectedImage: UIImage?
    if let editedImage = info[.editedImage] as? UIImage {
        selectedImage = editedImage
        self.profileImage.image = selectedImage!
        picker.dismiss(animated: true, completion: nil)
    } else if let originalImage = info[.originalImage] as? UIImage {
        selectedImage = originalImage
        self.profileImage.image = selectedImage!
        picker.dismiss(animated: true, completion: nil)
    }

}

This will work for sure.

The method signature has changed to

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any])

You should see a warning message for the func name

Instance method 'imagePickerController(:didFinishPickingMediaWithInfo:)' nearly matches optional requirement 'imagePickerController(:didFinishPickingMediaWithInfo:)' of protocol 'UIImagePickerControllerDelegate'

Candidate has non-matching type '(UIImagePickerController, [String : Any]) -> ()'

Move 'imagePickerController(_:didFinishPickingMediaWithInfo:)' to another extension to silence this warning

Make 'imagePickerController(_:didFinishPickingMediaWithInfo:)' private to silence this warning

Requirement 'imagePickerController(_:didFinishPickingMediaWithInfo:)' declared here (UIKit.UIImagePickerControllerDelegate)
