Operator

...(_:_:)

Returns a closed range that contains both of its bounds.

Declaration

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

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"
