contains(_:)
Returns a Boolean value indicating whether the given element is contained within the range.
Declaration
func contains(_ element: Bound) -> BoolParameters
- element:
The element to check for containment.
Return Value
true if element is contained in the range; otherwise, false.
Discussion
Because Range represents a half-open range, a Range instance does not contain its upper bound. element is contained in the range if it is greater than or equal to the lower bound and less than the upper bound.
