  1. Why do you think arrays in Swift only support a ​collection of objects of the same type. This is so that the array can be read easier and things can be kept clean. For example if you'd like to create a function where you are adding two numbers from the array and the index that you are using falls on a string, the program will return an error.

  2. How can you access objects within an array one at a time? you would call them based on their index for example arrayX.5

  3. How might you check if an array is empty? This can be done by checking isEmpty.arrayX
