This is used in the weakify pattern of Objective-C
My guess is that it means: assign a weak reference to self with the name 'weakSelf' and the typeof self (e.g. MyViewController)
If it's correct and looks obvious to you: I want to be absolutely sure to get this right. Thanks.

Yes, that is almost exactly what it means. The type of
self would be
MyViewController* (with an asterisk) not
The idea behind using this syntax instead of simply writing
MyViewController __weak *weakSelf = self;
is making it easier to refactor the code. The use of
typeof also makes it possible to define a code snippet that can be pasted anywhere in your code.
