min()
Publishes the minimum value received from the upstream publisher, after it finishes.
Declaration
func min() -> Publishers.Comparison<Self>Return Value
A publisher that publishes the minimum value received from the upstream publisher, after the upstream publisher finishes.
Discussion
Use min(by:) to find the minimum value in a stream of elements from an upstream publisher.
In the example below, the 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.
