Has anyone had success using #SwiftLang new #Observations with 6.2 strict concurrency to track #SwiftData #Model properties outside of #SwiftUI?

Can anyone (@twostraws.bsky.social @mecid.bsky.social @fatbobman.com @donnywals.bsky.social et al) help with some #Observations problems. I am trying to link a calculation method to modification of a few #SwiftData #Model types specific properties.

@mecid.bsky.social I am working with Observations and tried using your extension of Observable this morning and it throws errors about self of non-sendable Self and about KeyPath not being Sendable do you have any hints to resolve this?

It has been a process but the release of the #APCSA #CED is finally here. I have been waiting to be able to share about all the new content! It has been a pleasure working with so many FANTASTIC CS faculty. Shout out to all my friends!! apcentral.collegeboard.org/media/pdf/ap...
