In our latest Ask a Dev video, iOS architect Conrad Stoll discusses how to develop for the new larger screens of the iPhone 6 and the iPhone 6 Plus.
The first step is to decide how you want the app to be designed to take advantage of the larger screen size. Apple's given us a few good examples of this with its built-in apps for iOS 8, which show the user more content.
It will also be important to consider how the user is going to hold the larger phone, since controls on the top of the screen won't be as reachable.
Adaptive Layout, which Apple just announced this year with iOS 8, will make transitioning to larger screens much easier. In short, it helps you decide what type of layout you want to provide to different size classes of devices.
