title: How do I support large tab bar previews in iOS 11?
body: <p>In some of Apple's apps like Photos in iOS 11 if you hold down on a tab bar icon while your phone is in landscape and you have the larger accessibility size Dynamic Text turned on a large preview of the tab you are holding appearing. How do I support this in my app? Is it a new API or do I have to build it myself?
