Using @Observable is great, but it has one small caveat. The initializer of the @Observable objects will be called multiple times, even with @State

Yesterday I joined a book club session with iOS developers at Expedia who have been reading SwiftUI Fundamentals (books.nilcoalescing.com/swiftui-fund...). We talked through less obvious parts of SwiftUI, and they shared very positive feedback about the book. Made writing it feel worthwhile 😊

Initializing `@Observable` objects in SwiftUI views isn't as simple as it looks. 🧐
@natpanferova.bsky.social explains why you need `@State` and how to handle the lifecycle correctly.
