Apple has just released the new iOS 13.5 beta 4, iPasOS 13.5 along with tvOS 13.4.5 and watchOS 6.2.5 at the moment available for developers only.
As always, it is recommended that you install these betas only if you are a developer enrolled in the Apple Developer program, a practice that gives you access to download the profile and subsequent updating of the device used for testing through the iOS update features.
Keep in mind that with iOS 13.5, in addition to the well-known contact tracing API to deal with the COVID-19 emergency, there will also be improvements to the Face ID that will be able to understand if we are wearing a mask. Like all beta, it has several bug fixes for FaceTime.
This version contains the new exposure notification authorization screen which is activated only when an official app provided by public health authorities is installed. With beta 3, however, this toggle was already active by default, since without an app installed, the exposure notifications simply don’t work. Now, you can also delete exposure logs and manage officially installed applications.
As for Apple Watch, even this new build does not introduce tangible news. As with the previous three, therefore, the improvements should be concentrated under the hood, as MacRumors also speculates.
The same goes for Apple TV as the new beta does not bring any visible news with it. The beta 4 of tvOS will most likely integrate bug fixes and several performance improvements.
