# init(_:) Creates an environment property to read an observable object from the environment, returning `nil` if no corresponding object has been set in the current view’s environment. ``` init(_ objectType: T.Type) where Value == T?, T : AnyObject, T : Observable ``` ## Parameters `objectType` The type of the `Observable` object to read from the environment. ## Discussion> Important: This initializer only accepts objects conforming to the > `Observable` protocol. For reading environment objects that conform to > `ObservableObject`, use ``EnvironmentObject`` instead. Don’t call this initializer directly. Instead, declare an optional property with the `Environment` property wrapper, passing the object’s type to the wrapper: ``` @Observable final class Profile { ... } struct MyView: View { @Environment(Profile.self) private var currentProfile: Profile? // ... } ``` If no object has been set in the view’s environment, this property will return `nil` as its wrapped value. SwiftUI automatically updates any parts of `MyView` that depend on the property when the associated environment object changes. You can’t modify the environment object using a property like this. Instead, use the `View/environment(_:)` view modifier on a view to set an object for a view hierarchy. --- Copyright © 2026 Apple Inc.
