Рассмотрим функцию query

func query(address: String) -> String {
    let url = URL(string: address)
    let semaphore = DispatchSemaphore(value: 0)
    
    var result: String = ""
    
    let task = URLSession.shared.dataTask(with: url!) {(data, response, error) in

import Foundation

func query(address: String) -> String {
    let url = URL(string: address)
    let semaphore = DispatchSemaphore(value: 0)
    
    var result: String = ""
    
    let task = URLSession.shared.dataTask(with: url!) {(data, response, error) in
        result = String(data: data!, encoding: String.Encoding.utf8)!

    .delayWhen(idx => Rx.Observable.timer(delayFunction(idx)));

// usage
const withIncrementalBackoff = observable.retryWhen(backoff(3, nRetry => nRetry * 1000));
const withExponentialBackoff = observable.retryWhen(backoff(3, nRetry => nRetry * nRetry * 1000));
