On iOS, if devs are building with UIKit or SwiftUI, Dynamic Text can be well supported by just using parameterized fonts or font sizes alongside SF Symbols, no need to concern oneself with specific resolutions. With a little extra work, custom fonts are capable of this too[0]. Apps built this way will work well on devices with new resolutions or even form factors with little manual involvement on the dev’s part.
