Just ran into a question on how to implement NotificationCenter long-running listeners with modern AsyncSequence API, and have them torn down correctly. This seems to work.

#SwiftUI #StateObject

Yesterday we got some important info about how to initialize a StateObject with external values. https://mastodon.social/@lucabernardi/109948882720031817

Here’s a small exercise I did around that. All the behavior makes sense. You see all the ViewModels are only initialized once.

It’s not clear to me why the documentation uses a closure in example code for “Initialize state objects using external data”. StateObject initializer wrappedValue is already an autoclosure.
