# remove(at:) Removes and returns the element at the specified position. ``` @discardableResult mutating func remove(at position: Self.Index) -> Self.Element ``` ## Parameters `position` The position of the element to remove. `position` must be a valid index of the collection that is not equal to the collection’s end index. ## Return Value The removed element. ## Discussion All the elements following the specified position are moved to close the gap. This example removes the middle element from an array of measurements. ``` var measurements = [1.2, 1.5, 2.9, 1.2, 1.6] let removed = measurements.remove(at: 2) print(measurements) // Prints "[1.2, 1.5, 1.2, 1.6]" ``` Calling this method may invalidate any existing indices for use with this collection. > Complexity: O(*n*), where *n* is the length of the collection. --- Copyright © 2026 Apple Inc.
