    Parameters

    search

    The element to find in the asynchronous sequence.

    Returns

    true if the method found the element in the asynchronous sequence; otherwise, false.

    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"
