Ownership follows the [The Create Rule](https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFMemoryMgmt/Concepts/Ownership.html#//apple_ref/doc/uid/20001148-103029). ## Return Value `true` if `bundle` is loaded or upon inspection appears to be loadable, otherwise `false`. ## Discussion If this function returns true, this does not mean that the bundle is definitively loadable, since it may fail to load due to link errors or other problems not readily detectable. --- Copyright © 2026 Apple Inc.
