    Thanks! Your tutorials are amazing, and they help me understand and work more than when I did not find your helpful videos. Keep publishing excellent tutorials and help us more!!
    Here is a question: how newly added ones can be deleted after it is launched? I do not want some to remain in the list. Do I need to make a function that serves as a delete button? Then could you show me the code to do that? It would be helpful for others as well. Thanks again 🙂

    Hey Rod, for some reasons I can't find the reply button below your comment.
    If you want to save an image in CoreData, when you choose the attribute type in an entity, select binary data type.

    Excellent tutorial, thank you very much for providing this information to us. Only suggestion: in a few instances, you were talking while typing and changing some entries you had made — for those of us typing along with you and whose eyes must leave the screen for a few moments to check our own typing, we sometimes miss such changes. Other than that, I found this extremely helpful.
