Follow the Support Article below. Hopefully you had a backup done on the stable commercial release of iOS 18 which you will need to restore, otherwise you may not be able to restore or even lose some data.

Report issues found to Apple or to third-party app developers.


Resetting to revert to iOS 18.6.2 means no local data is preserved.


Resetting and restoring means some local data — that which has changed since the beta was installed — is lost.


If there are no backups created immediately prior to the installation of the beta, all local data is lost.


iCloud data is probably still available, and apps can be re-downloaded, independent of the reset.

But I’d likely stay with the iOS 26 beta through its upcoming release, as that probably avoids data loss.


Apple is having an announcement on September 9th; Tuesday.
