Swift Concurrency - Best Practices?

I'm currently working on a new iOS app and I'm trying to get a handle on Swift concurrency. I'm struggling to understand the best practices for using `async/await` effectively. Specifically, I'm wondering about how to avoid race conditions and ensure data consistency when dealing with multiple concurrent tasks. Are there any specific patterns or libraries you'd recommend?

Great question! Using `async/await` correctly is crucial. One common approach is to use locks or barriers to synchronize access to shared resources. However, excessive locking can actually hurt performance, so it's important to use them judiciously. Another option is to consider using `DispatchQueues` with their associated serial and concurrent modes. For simple cases, the serial queue will often be sufficient. You should also explore the `Task` struct and its `value` property, which can be used to pass data between tasks.

Thanks for the insights! I'll definitely look into `DispatchQueues`. It sounds like avoiding excessive locking is key. Also, could you recommend any good resources for learning more about Swift concurrency in general?
