"Things like factories, adapters, and other design patterns are all thankfully not there."

Not sure I understand this? How does Obj-c enable the developer to avoid factories?

Agreed. I've had to use factories in Obj-C plenty. I guess the argument that I would make is that they are much easier to implement in Obj-C and require less boilerplate (especially if you use blocks), not that the pattern doesn't exist in Obj-C.
