ControlNotificationStream.contains(_:)

Description#

In this example, an asynchronous sequence called Counter produces Int values from 1 to 10. The contains(_:) method checks to see whether the sequence produces the value 5:

let containsFive = await Counter(howHigh: 10) .contains(5) print(containsFive) // Prints "true"

• Parameter search: The element to find in the asynchronous sequence.
• Returns: true if the method found the element in the asynchronous sequence; otherwise, false.
