# SecAccessCreateWithOwnerAndACL(_:_:_:_:_:) Creates a new access instance using the owner and ACL entries you provide. ``` func SecAccessCreateWithOwnerAndACL(_ userId: uid_t, _ groupId: gid_t, _ ownerType: SecAccessOwnerType, _ acls: CFArray?, _ error: UnsafeMutablePointer?>?) -> SecAccess? ``` ## Parameters `userId` The user ID that owns this ACL. `groupId` The group ID that owns this ACL. `ownerType` Flags that control whether the specified user ID or group ID owns the resulting ACL. See [`SecAccessOwnerType`](/documentation/Security/SecAccessOwnerType) for details. `acls` An array of ACL entries to associate with the access instance. `error` The address of an error instance. On error, the return value is `nil`, and the variable referenced by this parameter is overwritten with a instance that provides more information. ## Return Value The new access instance. In Objective-C, call the function to release it when you are finished using it. ## Discussion Use this method to create a customized access instance from [`SecACL`](/documentation/Security/SecACL) instances that you’ve created with the [`SecACLCreateWithSimpleContents(_:_:_:_:_:)`](/documentation/Security/SecACLCreateWithSimpleContents(_:_:_:_:_:)) method. If you want a default access instance, use the [`SecAccessCreate(_:_:_:)`](/documentation/Security/SecAccessCreate(_:_:_:)) method instead. --- Copyright © 2026 Apple Inc.
