let stream = AsyncStream<Int> { continuation in
    continuation.yield(0)
    continuation.yield(1)
    continuation.yield(2)
    continuation.finish()
}

let start = Date.now
for element in try await self.stream.delay(for: 0.5) {
    print("\(element) - \(Date.now.timeIntervalSince(start))")
}

// Prints:
// 0 - 0.5
// 1 - 1.0
// 2 - 1.5
