When configuring a largeContentImage or adjustsImageSizeForAccessibilityContentSizeCategory, it is important to use a pdf asset and preserve the vector data so the icons are crisp at any size.

Color contrast between text and background is very important for perceivability. As colors come closer to each other, they’re more difficult to distinguish. Notice that colors that work well with big font sizes may not for smaller text.
Hacks are accessibility’s worst enemy. An example. There is a ‘trick’ floating on the internet: if you want a button with an icon to the right of the text, set the semantic content attribute to force right to left. Great way to create focus traps.
You can add an observer to listen for changes in the content size category, in case it is more convenient than overriding traitCollectionDidChange(_:).
