# bundle() Expands to a bundle instance that’s most likely to contain resources for the calling code. ``` @freestanding(expression) macro bundle() -> Bundle ``` ## Overview Use the `#bundle` macro when you want to load resources like localized strings, images, or other items in a bundle regardless of whether your code executes in an app, a framework, or a Swift package. When invoked from an app, app extension, framework, or similar context, the expanded macro instantiates the bundle associated with that target. For code in a Swift package target, the macro provides the resource bundle associated with that target. For example, the following code sets the localized text of a UIKit `UILabel` by explicitly loading the bundle associated with one of the app’s view controllers: ```swift label.text = String(localized:"Game Over.", bundle: Bundle(for: MyViewController.self), comment: "Text for game over banner.") ``` You can simplify the `bundle:` parameter by invoking the `#bundle` macro instead, like this: ```swift label.text = String(localized:"Game Over.", bundle: #bundle, comment: "Text for game over banner.") ``` The `#bundle` macro back-deploys to earlier versions of the OS, as indicated by the macro’s availability. --- Copyright © 2026 Apple Inc.
