8.5 Range Matching in a switch Statement

The case statements within a switch construct may also be used to implement range matching. The following switch statement, for example, checks a temperature value for matches within three number ranges:

let temperature = 83

 

switch (temperature)

{

      case 0...49:

        print("Cold")

 

      case 50...79:

        print("Warm")

 

      case 80...110:

        print("Hot")

 

      default:

        print("Temperature out of range")

}
