Best Practice for Returning Immutable Objects?

[Karl Moskowski]

I have a few methods that return NSData objects, but the objects are created and manipulated as NSMutableData, and then copied to an immutable version along these lines:

        NSMutableData *myData = [NSMutableData data];
        :
        :
        return [NSData dataWithData:myData];

Would it be sufficient to cast, like this?
        :
        return (NSData *)myData;

Does this generalize to other non-collection classes, e.g., NSString?

TIA.
