Hello, Regarding EKEventStore, the WWDC session mentions that “you should only have one of these for your application.” In my app, I need to use the instance on both the main thread and a background thread, and I would like to share a single instance across them. However, EKEventStore is a non-sendable type, so it cannot be shared across different isolation domains. I would like to know what the recommended best practice is for this situation. Also, do I need to protect the instance from data races by using a lock? Thank you.
