# CFTreeCreate(_:_:) Creates a new CFTree object. ``` func CFTreeCreate(_ allocator: CFAllocator!, _ context: UnsafePointer!) -> CFTree! ``` ## Parameters `allocator` The allocator to use to allocate memory for the new tree. Pass `NULL` or kCFAllocatorDefault to use the current default allocator. `context` The [`CFTreeContext`](/documentation/CoreFoundation/CFTreeContext) structure to be copied and used as the context of the new tree. The information pointer will be retained by the tree if a retain function is provided. If this value is not a valid C pointer to a [`CFTreeContext`](/documentation/CoreFoundation/CFTreeContext) structure-sized block of storage, the result is undefined. If the version number of the storage is not a valid [`CFTreeContext`](/documentation/CoreFoundation/CFTreeContext) version number, the result is undefined. ## Return Value A new CFTree object. 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). ## Discussion --- Copyright © 2026 Apple Inc.
