- - - - Array sample: var myFirstArray = ["Hoff", "Mariana"]

      - No item can appear twice in a set; all items must be unique.
      - Set sample: var myFirstSet = Set(["Hoff", "Mariana"])
- - - - You can’t add or remove items from a tuple;
      - You can’t change the type of items in a tuple;
      - You can access items in a tuple using numerical positions or by naming them.
      - Tuple sample: var myFirtTuple = (iAm: "Hoff", sheIs:"Mariana")
      - You have two ways to get a value from a tuple
        
        myFirstTuple.0
        
        myFirstTuple.first
