Weeks after being released to developer beta testers, Apple has now updated the public TestFlight app with support for iOS 13’s new features, in version 2.5.0.
The application, that allows you to beta test others’ apps before they appear on the App Store, now works with Dark Mode and will change with your system theme. So, if you have a light mode set, it’s likely that you’ll notice nothing.
Furthermore, Apple says that stability and performance improvements are also included in this update. You can download it from the App Store now.
