No. In Cocoa, exceptions are used to indicate programmer error, not runtime failure. In general, Cocoa isn't exception safe, so if an exception occurs, your app should do its best to gracefully shut down, save data (without overwriting known-good data, since you can't be sure the app is in a good state), with an explanation to the user. > or is 'init'ing a special case? -init isn't special with respect to the above convention regarding exceptions, but it does have its own conventions. Among those is that failure is indicated by returning nil.
