EnvironmentObject

@propertyWrapper
public class EnvironmentObject<ObjectType> : DynamicProperty where ObjectType : ObservableObject

Used to reference and observe environment objects previously set. Environment objects are identified by their type, meaning only one of the same type can exist at a time as an environment object.

Important

Referencing an environment object not previously set will trigger an exception.

  • A wrapper of the underlying ObservableObject that can create Bindings to its properties using dynamic member lookup.
