Matching Ranges and Tuples

Switch on numeric ranges and tuple shapes.

Matching a Range

A case can match a whole range of values using range operators like 1...5. If the value falls in the range, the case runs.

let score = 85
switch score {
case 0..<50:
    print("Fail")
case 50...100:
    print("Pass")
default:
    print("Invalid")
}

Use closed ranges (...) to include the upper bound and half-open ranges (..<) to exclude it. Pick boundaries that do not overlap.

let age = 18
switch age {
case 0..<13:
    print("Child")
case 13..<20:
    print("Teen")
default:
    print("Adult")
}
