Subscript

subscript(_:)

Returns the object at the specified index of the set.

Declaration

subscript(idx: Int) -> Any { get }

Parameters

index

The object located at index.

Return Value

If index is beyond the end of the ordered set (that is, if index is greater than or equal to the value returned by count), an rangeException is raised.

Discussion

This method is the same as object(at:).
