ControlNotificationStream.allSatisfy(_:)

Description#

In this example, an asynchronous sequence called Counter produces Int values from 1 to 10. The allSatisfy(_:) method checks to see whether all elements produced by the sequence are less than 10.

let allLessThanTen = await Counter(howHigh: 10) .allSatisfy { $0 < 10 } print(allLessThanTen) // Prints "false"

The predicate executes each time the asynchronous sequence produces an element, until either the predicate returns false or the sequence ends.

If the asynchronous sequence is empty, this method returns true.

• Parameter predicate: A closure that takes an element of the asynchronous sequence as its argument and returns a Boolean value that indicates whether the passed element satisfies a condition.
• Returns: true if the sequence contains only elements that satisfy predicate; otherwise, false.
