Apple has started rolling out iOS 18.7.8 and iPadOS 18.7.8 to iPhone and iPad users. The internal build number is 22H352, and this release arrives 29 days after the previous public version. As with many Apple rollouts, availability may appear at slightly different times depending on regional server cache refresh timing, so some users may see the update a little later than others.
In the official release notes, Apple only says the update delivers bug fixes for iPhone and iPad. Reports referenced by IT Home point to the actual issue addressed here: under some conditions, push notifications that had already been deleted could still remain visible on the device. That made the notification view look out of sync with what the user had already cleared.
So while this is not a feature-heavy release, it still fixes something practical. If your device was holding onto old alerts after they were dismissed, this patch is meant to clean that up and restore expected notification behavior.
IT Home also included a long update history for the 18.7 branch, which shows Apple has been maintaining this line steadily through release candidates, minor fixes, and beta milestones. The branch most recently moved through iOS 18.7.7 in March 2026, with earlier maintenance releases such as iOS 18.7.6, iOS 18.7.5, and iOS 18.7.4 appearing earlier in the cycle.
Looking back further, the broader iOS 18 family progressed through iOS 18.6, iOS 18.5, iOS 18.4, and multiple beta and release candidate builds across 2025 and late 2024. That timeline gives a clearer sense of how Apple has continued supporting older software tracks while still moving newer branches forward in parallel.
For most users, the takeaway is simple: Apple software update 18.7.8 is a maintenance release focused on a specific notification bug. It does not appear to introduce new visible features, but it does target a lingering issue that could make previously deleted alerts stick around longer than they should.
