Yes, you can still send applications, as usual, without adjusting your application for newer screen sizes. It will automatically scale for iPhone 6 and iPhone 6 Plus (similar to how iPad scaling works for iPhone applications, but better). You should still test your application against these targets in Xcode 6. I already found one zoom problem using GLKViews only on iPhone 6 Plus. ContentScale factor increased to 3 instead of 2 ONLY on iPhone 6 Plus. I will also notice that when you submit the application to the application store, you still need to take screenshots for all screen sizes. Therefore, despite this, you must run all the dimensions of the device.
