Swift 4.2 imagePickerController问题

UIImagePickerControllerEditedImage //无法使用索引类型为“UIImagePickerController.InfoKey”的类型'[String：Any]’下标

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)
}

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

您应该看到func名称的警告消息

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)
