Returns a half-open range that contains its lower bound but not its upper bound.
static func ..< (minimum: Self, maximum: Self) -> Range<Self>
The lower bound for the range.
The upper bound for the range.
Use the half-open range operator (
..<) to create a range of any type that conforms to the
Comparable protocol. This example creates a
Range<Double> from zero up to, but not including, 5.0.
let lessThanFive = 0.0..<5.0 print(lessThanFive.contains(3.14)) // Prints "true" print(lessThanFive.contains(5.0)) // Prints "false"
