Apple, Is USB Allowed Now?
In the wake of the success of the Duet Display app, is using the USB connection in iOS allowed?
[…]
We knew that using USB instead of Wifi was a decision we had to make early on, as it would completely change our direction of development. USB offers a reliable, low latency connection which is 100x better than any wireless technology (especially with Yosemite experiencing serious Wifi reliability issues).
We were also very hesitant to build a business around a decision Apple may change on a whim. So we submitted an app to test the waters, would Apple allow an app that requires USB? An Apple representative called us and informed us USB connectivity was not allowed.
