I just discovered that my OS X apps will not open documents residing in iCloud
Drive upon double-clicking. My app activates, but nothing opens. At first I
thought this might be an intentional restriction by Apple, but such a silent
failure will be very confusing to users who have not studied sandboxed vs.
nonsandboxed apps! I would expect at least a Gatekeeper-like warning.
Furthermore, if I click in my app File > Open and navigate into iCloud Drive, I
can open documents as expected.
Does anyone know what’s going on here?
Thanks,
Jerry
DETAILS
The test is to move one of my app’s documents into iCloud Drive, then
double-click or secondary-click and “Open” or “Open with”. I have activated
breakpoints or in the following methods:
In my NSDocumentController subclass:
-openDocumentWithContentsOfURL:display:completionHandler:
-openDocumentWithContentsOfURL:display:error:
-makeDocumentWithContentsOfURL:ofType:error:
In my NSPersistentDocument subclass:
-readFromURL:ofType:error:
-readFromFileWrapper:ofType:error:
-readFromData:ofType:error:
In my app delegate:
-application:openFile:
Result: My app activates and remains, but none of these methods gets invoked.
Instead, I see the messages like these in the system console:

It looks like this “bird” process (something which flies around in iCloud -
very cute?) is being denied by sandboxd. The second message, from sandboxd,
has attached a “Full Report”, as shown below. The report has the form of a
crash report, but is apparently just a snapshot of bird's state. Nothing
crashed.
