For other UI elements that could also benefit from being scaled when using Dynamic Type, you can use UIFontMetrics's scaledValue(for:). Some good examples are progress bar components, which tend to be quite slim.

I wish the adjustsFontForContentSizeCategory was true by default. Instead, you need to configure it that way so elements adjust their font size as the content size category (dynamic type) changes when a preferred font is used for a given style.
Manual testing is crucial. And therefore, reducing friction to let you start your testing process can be a huge help. Selecting some accessibility shortcuts will do that, putting most of iOS' accessibility features at a triple-click of a button.
Since iOS 14, you can get a human readable localised name for a UIColor, with a very useful property called accessibilityName, that you can use in accessibility attributes like labels or values. How cool is that? https://developer.apple.com/documentation/uikit/uicolor/accessibilityname
