    Parameters

    pattern

    A range.

    bound

    A value to match against pattern.

    You can use the pattern-matching operator (~=) to test whether a value is included in a range. The pattern-matching operator is used internally in case statements for pattern matching. The following example uses the ~= operator to test whether an integer is included in a range of single-digit numbers:

    let chosenNumber = 3
if 0..<10 ~= chosenNumber {
    print("\(chosenNumber) is a single digit.")
}
// Prints "3 is a single digit."
