# min() Publishes the minimum value received from the upstream publisher, after it finishes. ``` func min() -> Publishers.Comparison ``` ## Return Value A publisher that publishes the minimum value received from the upstream publisher, after the upstream publisher finishes. ## Discussion Use [`min(by:)`](/documentation/Combine/Publisher/min(by:)) to find the minimum value in a stream of elements from an upstream publisher. In the example below, the [`min(by:)`](/documentation/Combine/Publisher/min(by:)) operator emits a value when the publisher finishes, that value is the minimum of the values received from upstream, which is `-1`. ``` let numbers = [-1, 0, 10, 5] numbers.publisher .min() .sink { print("\($0)") } // Prints: "-1" ``` After this publisher receives a request for more than 0 items, it requests unlimited items from its upstream publisher. --- Copyright © 2026 Apple Inc.
