Swift 4.2 imagePickerController issue

Trying to pass chat client from swift 4 to swift 4.2 and with picker i found trouble.

UIImagePickerControllerEditedImage Cannot subscript a value of type '[String : Any]' with an index of type 'UIImagePickerController.InfoKey'

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

    if let pickedImage = info[UIImagePickerControllerEditedImage] as? UIImage {
        self.userProfileImage.contentMode = .scaleAspectFit
        self.userProfileImage.image = pickedImage
    }

    picker.dismiss(animated: true, completion: nil)
}
Solution

  • 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)
