It's not an issue with `State` it looks a compiler issue.

```swift
struct S {
  var a: Int?
  var b: Optional<Int>

  init() {
    // error: Return from initializer without initializing all stored properties
  }
}

```

`a` will automatically be initialized with `nil` as a convenience feature, but `b` will not!

@Slava_Pestov @jrose maybe we should aim to remove this for Swift 6? The example of confusion about the effects it causes for `State` is a fair motivation. On top of that explicit `Optional` isn't treaded the same by the compiler anyways.

Edit: 🤦‍♂️ I meant to reply in this thread [SwiftUI @State PW exact same code different result if another optional is added!? :=(](https://forums.swift.org/t/swiftui-state-pw-exact-same-code-different-result-if-another-optional-is-added/62789) but accidentally replied here and just realized that @mayoff already explained the puzzle.
