Switches in swift don't need break statement as a case statement doesn't fall through by default.
You don't need to add a break to the end of all your cases.
To fall through a case to those below, Swift has the fallthrough keyword for this very reason:
let fallthroughSwitch = 10 switch fallthroughSwitch { case 0..<20: // w w w. ja v a2 s . c om print("Number is between 0 and 20") fallthrough case 0..<30: print("Number is between 0 and 30") default: print("Number is something else") }
