I recently started learning Swift and Swift UI and was surprised at how complicated the language is. Especially regarding reactive instance variables. eg. @observableObject. Didn't understand it. There are like five different ways to do it. Ended up playing whack a mole until it worked.

I had the same experience until I worked with swiftdata which was rather nice, especially by comparison.

If you’re targeting newer OSs you can try the @Observable macro instead of ObservableObject. It fixes a lot of the weird problems with the latter (although does introduce some new, weird edge cases).

TBF, reactivity in UI is still basically an unsolved problem with frameworks going in circles between data-binding, dependency-tracking, memoization & compilation. SwiftUI initially promoted their ReactiveX alternative.
