this is how we handle a bool :/
Are you sure that you are using isTurnableToJSON the

You can access immutable Foundation objects across threads, but not mutable
ones, which is what you're thinking of. Your

I believe that reading is thread safe, but writing is not. You could wrap all
access to the array in methods which use the same GCD queue to read/write, and
that would be thread safe.

It depends. The short answer: you should use your own synchronization around
your own critical sections instead of relying

You’re calling it on the NSData? That’s the wrong way round. You call that
method to ask if you can turn an in-memory data structure _into_ JSON data, not
to see
I am trying to add an icon to only one NSMenuItem item but it is indenting the
icon and text by 1 level.
I tried to set the setIndentationLevel to 0 but that doesn't work.
An example of what I am trying to achieve can be seen in the Wireless status

No. The atomic just means you can access the array property atomically, not
that methods called on that array are synchronized. For that you need to do
your own synchronization, like using @synchronized on the array itself.

You have to add a counter.

You can add a counter, which is pretty easy. Or you can call
-enumerateObjectsAtIndexes:options:usingBlock:, which passes the index as well

If you use a block-iterator, the index is passed as a parameter to the iterator
block.
