# subscript(dynamicMember:) Returns the attribute container that corresponds to a specified key path. ``` subscript(dynamicMember keyPath: KeyPath) -> ScopedAttributeContainer where S : AttributeScope { get set } ``` ## Discussion Use this subscript when you need to work with an explicit attribute scope. For example, the SwiftUI [`foregroundColor`](/documentation/Foundation/AttributeScopes/SwiftUIAttributes/foregroundColor) attribute overrides the attribute in the AppKit and UIKit scopes with the same name. If you work with both the SwiftUI and UIKit scopes, you can use the syntax `myAttributeContainer.uiKit.foregroundColor` to disambiguate and explicitly use the UIKit attribute. --- Copyright © 2026 Apple Inc.
