Question 1

How do I use Queuer with Swift's async/await?

Accepted Answer

Set manualFinish to true in your ConcurrentOperation and call finish(success:) inside the async task, as detailed in the README. This ensures proper lifecycle management, but adds boilerplate and risk if finish() is forgotten.

Question 2

What's the difference between Queuer and using OperationQueue directly?

Accepted Answer

Queuer provides a higher-level abstraction with built-in features like automatic retry and chained operations, reducing boilerplate for common tasks. However, it adds a layer that might obscure low-level GCD control for advanced use cases.

Question 3

Can Queuer handle background tasks on iOS?

Accepted Answer

Yes, Queuer leverages OperationQueue and GCD, which are designed for background execution. You can configure quality of service and use schedulers for recurring tasks, as shown in the usage examples for cross-platform compatibility.

Question 4

How to implement retry logic with Queuer?

Accepted Answer

Enable automatic retry by setting operation.success to false in the execution closure and defining maximumRetries. For manual retry, set manualRetry to true and call retry() as needed, but be cautious to avoid blocking the queue.

Question 5

Is Queuer compatible with the latest Swift version?

Accepted Answer

According to the requirements table, Queuer 3.0.0 supports Swift 5.9 to 5.10 and all major Apple platforms including visionOS, plus Linux. Always check the GitHub repo for updates to ensure compatibility.

Question 6

What happens if I forget to call finish() in an async operation?

Accepted Answer

The queue will be blocked indefinitely, as warned in the README's caution notes. Always set manualFinish and ensure finish() is called to prevent deadlocks in your application.
