How can I make an app fit the full 5.5 inch screen? The guidelines in Layout do not have that option. Thanks.

You can create a custom set of guidelines to match the iPhone screen.
I usually just get things "close", a few pixels under and then put a hidden object in the bottom right corner with right and bottom auto-size anchors only specified. This stretches the layout out the final pixels to a perfect fit and should produce a layout that is at least minimally acceptable on iPhone with a slightly larger screen.
This Knowledge Base article is very helpful when it comes to working out the layout size for various iOS devices with different orientation/toolbar/menu bar options:
