iOS and Xcode provide a wide variety of tools and options to deal with color contrast ratios. From system colors, that automatically support Increase Contrast, to high contrast color and asset variants, and even a built-in contrast calculator.
With the Accessibility Inspector you can check the value for the most common accessibility attributes for individual elements, do some basic navigation, and even perform actions if the component is adjustable or if it has custom actions.
You don't have to offer an alternative layout just for the accessibility category. You can actually compare content size categories. So you could tweak the UI already for anything equal to or larger than .extraExtraLarge, for example.
