Hello, I get the error in the class "InteresesViewController.swift" and in this part of the code:  for index in arr{         selectInteres.append(feedInterests[indexPath.row] as! String)       } From that data that is shown to the table, the user must select the data, whatever it is, and the selected data must be stored in an array. The intention is that only the "jsonElement [" interesNombre "]" string are saved in the array. Thanks!

Hello, thank you very much for the help! I really appreciate your patience and enthusiasm for supporting me. With great regret I tell you that I do not have enough knowledge in Swift. What I have in the app is based on tutorials that I have seen and that I have learned over time. I will take your recommendations into account as it inspires me to improve my development with Swift. Thank you very much for your help. I send you a hug!
