Add Large Content Viewer to custom bars

21 Sep 2022

You should really try to support Dynamic Type. If you can’t for some reason, and you want to fall back to the Large Content Viewer, you can do so. I’d limit it to “sticky” bars. Maybe you have a custom tab bar, navigation bar, or similar?

Check the UILargeContentViewerItem protocol. Most UIKit components conform to it already. You'll just need to set showsLargeContentViewer to true and add a UILargeContentViewerInteraction to your component.

Some of you have asked me how you can support what I do. This would really help, and would be hugely appreciated:

  • Find these posts useful? Share them at work, on social media, or with anyone that might find them interesting. Let's spread the word!

  • Check out any of my apps or games: Xarra!, RetroRapid!, or Mestre!.

    • A download and a review go a long way. They're free by default. On the App Store, ratings and reviews really help more people discover them.

    • Finding any of them useful? If so, and if you can afford it, purchasing lifetime access to all features or subscribing lets me buy the coffee that keeps me caffeinated. Caffeine keeps me going to maintain the apps, bring in new features that I hope you'll love, and keep writing.

You may have noticed that navigation/tool/tab bars don't scale with large Dynamic Type sizes. It would take too much space from the screen leaving very little real estate for the actual content. A tap and hold will show the Large Content Viewer.

There are a ton of things to love about SwiftUI. But one of my favorites it's got to be the possibility of previewing Variants: the possibility of seeing your UI in dark/light modes, all dynamic type sizes, and orientations, side-by-side.

Make sure you support Dynamic Type up to the largest text size available. Take into account that there are five extra accessibility sizes available from the Accessibility Settings. It can make a huge difference for lots of users.
