Throttling calls for searching in Swift

Updated 4 July 2023


Throttling is mainly used for the searching tasks whenever a user types fast to make sure that, backend server doesn’t receive multiple requests. if you send multiple requests to the server and canceling the request it increases the load on the server if the server is paid and it also increases the cost too much.

Best way to implement is throttler by using the RxSwift but the question is for the single task why you use RxSwift the better way you can use the GCD for this.

For implementing throttler you can use the DispatchWorkItem from this you can set a pause to the request or on a task and cancel the previous task. Check the implementation of throttler:-

How to use it:-

I hope from this, it will make you more comfortable dealing with Throttling calls. Thanks for tuning in once again!
