When developing an iOS application, it is a common need to handle the frequency at which information is processed. For example, when making changes to a search field, we might want to request a remote API for each update. However, sending too many requests in quick succession can cause the server to become overloaded. To avoid this issue, it is important to pace the requests in order to prevent overloading the server. One solution to this problem is to use reactive programming and apply a Debounce operator to a stream of user inputs. However, if you don't want to use reactive programming, async sequences, or third-party libraries, you can explore a solution using pure Swift concurrency. In this article, we will look at how to use this approach to manage the frequency of information processing in an iOS application.
