Swift - Switches with range


Switches in Swift can use ranges as cases.

You can create code that runs when the value you're testing falls between certain ranges:


var someNumber = 15 
switch someNumber { 
case 0...10: // ww  w.java  2s . c  om
    print("Number is between 0 and 10") 
case 11...20: 
    print("Number is between 11 and 20") 
case 21: 
    print("Numer is 21!") 
    print("Number is something else") 


If multiple cases in a switch statement overlap-for example, case 0...10 and case 5...15-then the first matching case will be used.
