Does the method use NSObject init?

Does it make sense to write self = [super init];in a custom initialization method when subclassing NSObject? I know this is necessary when subclassing any other class, since it can have custom initialization, but does the NSObject init method do nothing?

The object is not ready for use until it is initialized. The method initdefined in the class NSObjectdoes not initialize; it just returns self.

So basically you don’t have to call [super init]in a subclass NSObject, but I would recommend it. It is simply the best design. If you change the superclass, it will still work.
