  11. Implicit Sharing

  12. Inheritance too intrusive • You can only have 1 super

    class • Bloating your super class • If superclass have stored properties ◦ You have to accept them, which bloat it ◦ You have to initialize it ◦ Make sure that you understand how to interact with your superclass

  13. Lost Type Relationships

  14. Protocol Solves the Problems
