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.

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. https://developer.apple.com/documentation/uikit/uilargecontentvieweritem
It is possible to use custom fonts and for them to still work great with Dynamic Type. You need to define the default size and use UIFontMetrics to get the scaled font for each one of the styles you'd like to use. https://developer.apple.com/documentation/uikit/uifontmetrics/scaledfont(for:)
