# max() Returns the maximum element in an asynchronous sequence of comparable elements. ``` @warn_unqualified_access func max() async rethrows -> Self.Element? ``` ## Return Value The sequence’s maximum element. If the sequence has no elements, returns `nil`. ## Discussion In this example, an asynchronous sequence called `Counter` produces `Int` values from `1` to `10`. The `max()` method returns the max value of the sequence. ``` let max = await Counter(howHigh: 10) .max() print(max ?? "none") // Prints "10" ``` --- Copyright © 2026 Apple Inc.
