Matthew Panzarino for The Next Web:

We reached out to a few active iOS developers to get their thoughts on whether the larger screen would mean delays or a more difficult development process. The general consensus was that it shouldn’t pose too many huge problems, but that it would be a lot easier to test their apps if they had a device in their hands.

Glad to hear it is a surmountable issue, but there’s no question that it’s going to take a while for iOS developers to get up to speed with the new hardware.
