Searching for: Lists in Swift
Arrays are used to assign a series of elements of the same type in consecutive memory locations; to define a list of elements. They work similar to variables, except they contain multiple values at different indices.
A switch case is used test variable equality for a list of values, where each value is a case. When the variable is equal to one of the cases, the statements following the case are executed. In Swift, a switch case can contain a temporary let constant, which contains the variable's value. This let constant can be used in a booleanExpression, which if true, will evaluate statements
