# subscript(unchecked:) Accesses the element at the specified index in the `Span`. ``` subscript(unchecked position: Span.Index) -> Element { get } ``` ## Parameters `position` The offset of the element to access. `position` must be greater or equal to zero, and less than `count`. ## Overview This subscript does not validate `position`. Using this subscript with an invalid `position` results in undefined behaviour. > Complexity: O(1) --- Copyright © 2026 Apple Inc.
