# min() Returns the minimum element in the sequence. ``` @warn_unqualified_access func min() -> Self.Element? ``` ## Return Value The sequence’s minimum element. If the sequence has no elements, returns `nil`. ## Discussion This example finds the smallest value in an array of height measurements. ``` let heights = [67.5, 65.7, 64.3, 61.1, 58.5, 60.3, 64.9] let lowestHeight = heights.min() print(lowestHeight) // Prints "Optional(58.5)" ``` > Complexity: O(*n*), where *n* is the length of the sequence. --- Copyright © 2026 Apple Inc.
