While the iOS 18.3 Beta 3 update is mainly aimed at fixing bugs and security issues, it still includes some new features:

  • Robot vacuum support: This feature is part of Apple's Homekit app and was supposed to be released back in 2024 but has been delayed till 2025. An X user, @aaronp613, spotted code changes in the new update, which revealed the support for robot vacuum devices.
  • Repeated Math Operations makes a return: Before iOS 18 first arrived, you could repeat math operations in the Calculator app, but it was seemingly removed after the update. However, this ability has returned in the iOS 18.3 Beta 3.
  • Updated Camera Control icons: The Camera Control icons have been updated with support for Dark Mode.
  • Disabling satellite communications: The satellite communication system is an emergency communication service that can be used when there is no cellular or internet connection available. However, a few consumers were concerned that it could be used to spy and track the user's location. With this update, users will be able to disable satellite communications.

When will the iOS 18.3 stable update release?

There was a large gap between the release of iOS 18.3 beta 1 and beta 2 due to the holiday season, but it seems we are back on track with this release of beta 3. So, you can expect beta 4 to arrive sometime next week, which will be followed by a Release Candidate (RC) update the week after that. As such, the stable version won't be released anytime before February 2025.
