Please refer to the Cocoa thread safety documentations:

Could you please point to the exact section where it is stated that
it is not OK to update a bound property from a background thread?
The part where it doesn't say it's safe to do so.
Your -add2Number: method is safe, but that's because it's updating sum
from the main thread, not a background thread. If you were invoking -
setSum: (which is what "self.sum =" does) from -add2Number: then it
wouldn't be safe.
