Developers have done some pretty impressive work on their apps for the new iPhone Duo—and fast. Samsung might be jealous.

I opened up the simulator on my app yesterday thinking it probably needed updates to get ahead of it.

To my surprise it worked automatically on the duo with no adjustments.

I think if you made an app recently in swift, and everything worked on iPhone and iPad already, it may be properly resized already, similar to how android handles scaling automatically.
