That won’t crash, because all instance variables are automatically initialized to nil. Sending the addObject: message to a nil object won’t crash — but neither will it do what you want. Instead, it won’t do anything, and your ‘foo’ object won’t get added — probably not what you want. Also, I wouldn’t give the user direct access to your internal NSMutableArray and let them monkey with it directly. Instead, implement a to-many property backed by the NSMutableArray, with which the users of the class can interact instead of directly with the array.
