We leverage “Nonisolated Core, Isolated Shell” by introducing the StoreActor: a Store-like object that runs in the background on the cooperative thread pool, maximizing parallelism for tests and non-UI features.

Have you used Swift’s revamped NotificationCenter APIs? Do you know how they differ from the 22 year old APIs they replace? It’s all about concurrency, sendability, and actor isolation.

NotificationCenter’s old observation APIs take @‌Sendable closures because they can be executed on any thread that posts the message.

But @‌Sendable closures make very basic operations, like mutating your app’s state, quite difficult to do.

NSNotificationCenter was built for NeXTSTEP in Objective-C way back in 1994, but it had a major update for Swift concurrency just last year!

This week we look at the original API as it landed in Swift, preconcurrency, the good and the bad. pointfree.co/episodes/ep385…

Let’s explore another example of designing code with isolation in mind, inspired by NotificationCenter. We’ll take a trip down memory lane to see how Swift adopted the original NeXTSTEP implementation, before concurrency, and its trade-offs.
