Matching a Range

A single case in a switch statement can match a range of values.

let number = 20
switch number {
case 0:
    print("Zero")
case 1..<10:
    print("Between One and Ten")
case 10..<20:
    print("Between Ten and Twenty")
case 20..<30:
    print("Between Twenty and Thirty")
default:
    print("Greater than Thirty or less than Zero")
}
