If you use Interface Builder to build your app’s layout, there are some basic accessibility attributes that can be configured from there. They can be found in the Identity Inspector in the right-side panel in Xcode.
The Accessibility Inspector lets you configure on or off some of the most common accessibility options so you can conveniently observe how your app adopts these options in the simulator or device. You can also quickly select different text sizes.
Make sure you support Dynamic Type up to the largest text size available. Take into account that there are five extra accessibility sizes available from the Accessibility Settings. It can make a huge difference for lots of users.
