If you have any web views in your app (Terms and Conditions and Privacy Policy, I'm looking at you), you can also support Dynamic Type for them. You can set an Apple system font with the same styles available for native development in your CSS.
Touch target sizes are recommended to be at least 44 x 44 points. Buttons in the navigation bar ( especially when not using nav bar button items), dismiss buttons, and custom toolbars, are use cases that tend to have smaller sizes.
A common example where you need to manually configure the button accessibility trait is for some table/collection view cells. These tend to be “buttons” that perform an action, like playing music, or bring the user to a different screen.
