Operator

...(_:_:)

Returns a closed range that contains both of its bounds.

Declaration

static func ... (minimum: Unicode.Scalar, maximum: Unicode.Scalar) -> ClosedRange<Unicode.Scalar>

Parameters

minimum

The lower bound for the range.

maximum

The upper bound for the range.

Discussion

Use the closed range operator (...) to create a closed range of any type that conforms to the Comparable protocol. This example creates a ClosedRange<Character> from “a” up to, and including, “z”.

let lowercase = "a"..."z"
print(lowercase.contains("z"))
// Prints "true"

static func ..< (Unicode.Scalar, Unicode.Scalar) -> Range<Unicode.Scalar>
