Apple has officially pushed out iOS 18.7.9 and iPadOS 18.7.9 for supported iPhone and iPad users. The new release carries build number 22H355 and arrives 12 days after the previous public version, though Apple hasn’t yet published a detailed changelog explaining exactly what was fixed or adjusted in this release.
That lack of public detail means this looks like a smaller maintenance update, at least for now. In cases like this, Apple sometimes rolls out quiet bug fixes, security patches, or under-the-hood stability changes before posting more specific release notes later.
The source report also notes that update detection can appear slightly delayed in some regions because of caching behavior on Apple’s server nodes. In practical terms, that means some users may not see the update instantly even if it’s already live, but the delay usually clears within about half an hour.
As a point of reference, the previous release in this branch was iOS 18.7.8, build 22H352, which arrived on April 23, 2026. Before that, Apple had issued iOS 18.7.7, an 18.7.7 RC build, and earlier maintenance updates throughout the year as the iOS 18 line continued to receive support alongside newer platform branches.
For users who stay on the iOS 18 track, this release appears to be the latest incremental update in that maintenance cycle. Until Apple publishes full notes, the clearest confirmed facts are the version numbers, the build 22H355 identifier, and the timing of the rollout.
