Dark Mode introduces a dramatic new look for iPhone and iPad that is seamlessly
integrated throughout the system and simple to turn on from Control Center
or Siri. With a dark appearance for all user interface elements, your app’s content
becomes the focus.
When Dark Mode is turned on, all apps built with the iOS 13 SDK
will run in Dark Mode. Learn how to optimize for Dark Mode, then test
your apps on a device running the latest beta version of iOS 13 or iPadOS.
If you need more time to make your apps look fantastic in Dark Mode, or if
Dark Mode is not suited for your app, you can learn how to opt out.
