Apple has rolled out iOS 26.4.1 for iPhone users following the release of iOS 26.4. This update addresses a frustrating bug that hindered users from syncing their iCloud data, impacting applications such as Apple Passwords. Although Apple has not provided detailed information about this software update, 9to5Mac uncovered a discussion on the Apple Developer Forums indicating that iOS 26.4.1 resolves the iCloud sync problem.
The discussion emerged after the release of iOS 26.4. A developer noted that alterations made to a document on a Mac did not prompt updates to the corresponding file on the iPhone. In response to this feedback, an Apple Worldwide Developer Relations representative proposed resolving the issue via macOS, suggesting that the app may not have transmitted data to CloudKit properly. As additional users reported the same concern, Apple began to take these reports seriously, leading to this update.
With iOS 26.4.1, the same Apple staff member engaged in the discussions inquiring if users experiencing the issue could upgrade to iOS 26.4.1 to check if the problem had been rectified. User feedback indicates that everything functions smoothly now.
