Arrays for Days

Swift supports a collection of objects of the same type in order to write safe code that only works with properties and methods on the type declared in the array definition.

If one wants to access all the objects in an array one at a time, one could use a loop to do this, more specifically, one might use the for…in loop to accomplish this.

To check if an array is empty, one might could use the .isEmpty property, otherwise, one might check the .count == 0, if it does not, then the array is not empty.
