Yes, it is a "bug". Because the return type of -initWithObjects is "id", which can represent any object, the compiler can't know that the types are incompatible. IIRC, you should get a compiler warning if you call a method that only NSArray implements, such as -objectAtIndex:, on the myCollection object. HTH, Keary Suska Esoteritech, Inc.
