While still in the process of cleaning up my code, I read in the documentation of NSObject that -init should return nil if it fails to initialize. But a paragraph lower it's stated that -init should always return a functional instance or raise an exception. Isn't that in conflict with the allowance of returning nil?
File a documentation bug. I would imagine the paragraph about the
exception is saying that an exception must be raised rather than
returning a half-constructed instance of the object.
I agree. The "must raise an exception" is a bug in the documentation IMHO.
There is a lot of recent API that used the 'return nil' pattern (especially methods design to return an NSError by ref).
Ah, I see. I hoped it was 'the new way to go'. I like to more than
checking for nil, but I might be a bit lazy :)
I'll file a bug to get the docs updated.
