Where did url come from? Presumably a bookmark, and since you expect it to be a
directory, it must be an application-scoped bookmark.
-startAccessingSecurityScopedResource will grant your app access to the
directory and all the files/folders etc. inside it (recursively).

Access is counter-based, so assuming you haven’t got any other calls to
-startAccessingSecurityScopedResource for the same location on the go, this
line of code has just cut off access.
Yes, you could first generate more bookmarks for each of the files inside the
directory, but that seems a weird thing to do for most use cases. Instead, just
keep access to the directory open until you’re finished with it.
