Swift Language Switch Using the where statement in a switch
Example
The where statement may be used within a switch case match to add additional criteria required for a positive match. The following example checks not only for the range, but also if the number is odd or even:
switch (temperature) {
case 0...49 where temperature % 2 == 0:
print("Cold and even")
case 50...79 where temperature % 2 == 0:
print("Warm and even")
case 80...110 where temperature % 2 == 0:
print("Hot and even")
default:
print("Temperature out of range or odd")
}
