 ## Using with SwiftUI
 
+### ObservableObject support
+
 `AsyncValue` can be adapted to work seamlessly with `ObservableObject` with a single line of code:
 
 ```swift
 class MyObservableObject: ObservableObject {
-    @AsyncValue var myValue: String = "Test" {
-        // IMPORTANT: you must use `willSet` as that is what `@Published` uses under the hood
-        willSet { objectWillChange.send() }
-    }
+    @AsyncValue var myValue: String = "Test"
 }
 ```
 
+Any changes to an `AsyncValue` will trigger a view update in the same way `@Published` does.
