Apple initially limited updates for devices eligible for iOS 26 to version 18.7.2. However, following the slow adoption of iOS 26 (largely driven by the controversial Liquid Glass interface) and the emergence of the DarkSword exploit, the company reversed course and took the unusual step of expanding iOS 18.7.7 (originally released only for the iPhone XS and XR) to all newer iPhone models to address the security threat.<ref>https://www.macrumors.com/2026/04/01/apple-ios-18-darksword-security-update/</ref> Apple would later do the same for iOS 18.7.8.

''See Apple's official [https://support.apple.com/en-us/121161 release notes] and official [https://support.apple.com/en-us/124925 security update contents].''

== Reception == Reception of iOS 18 was mixed to positive from critics and users; it was praised for its deep personalization and new satellite features but criticized for its numerous bugs from the initial versions and the gradual rollout of AI features.
