• 1Choice 1.

  objectWillChange is published right before a @Published property changes, and SwiftUI receives it and re-evaluates the subscribed views' bodies in the next render cycle

• 2Choice 2.

  When just one @Published property on an object changes, every view that subscribes to that object through @StateObject or @ObservedObject becomes a candidate for re-evaluation

• 3Choice 3.

  @Published notifies after the value changes, so the view can always read the latest value, and there is no willChange moment

• 4Choice 4.

  Updating @Published from a background thread produces the "Publishing changes from background threads is not allowed" warning and can leave the UI out of sync

• 5Choice 5.

  @Published can also be declared inside a struct and SwiftUI observes it the same way
