Question 1

How to use Throttler for debouncing user input in a SwiftUI search bar?

Accepted Answer

Wrap the search update logic in a debounce call with a custom identifier, such as debounce(.seconds(0.5), identifier: 'search') { // fetch results }. This delays execution until after input pauses, reducing unnecessary network calls.

Question 2

Throttler vs Combine: which is better for throttle operations?

Accepted Answer

Throttler is simpler and more lightweight for basic throttle/debounce tasks, requiring less code and no reactive programming knowledge. However, Combine is built into Swift and offers a wider range of operators if you need more complex reactive pipelines.

Question 3

Can I run multiple throttle instances with different settings in Throttler?

Accepted Answer

Yes, by using custom identifiers, you can manage separate throttle or debounce instances independently. For example, throttle(identifier: 'apiCall') and throttle(identifier: 'uiUpdate') will operate without interfering with each other.

Question 4

How to migrate from Throttler's struct-based methods to actor-based in V2.0.0?

Accepted Answer

Replace deprecated struct calls with the new function-based API, such as using throttle() directly instead of Throttler struct methods. Update your code to rely on Swift's actor model, and ensure your app targets the required OS versions (iOS 16.0+).

Question 5

Is Throttler thread-safe when modifying shared variables?

Accepted Answer

Yes, Throttler ensures thread safety by using Swift's actor model within closures. As shown in the thread-safe test example, you can safely increment shared variables across multiple threads without data races.

Question 6

What are the key differences between throttle and debounce in Throttler?

Accepted Answer

Throttle limits execution to once per time interval, while debounce delays execution until after a pause in triggers. Throttler adds options like 'ensureLast' to guarantee the final call in throttle, and 'runFirst' for immediate execution in debounce.
