iOS 18 supports the same iPhone models as iOS 17, starting with the iPhone XS launched in 2018. Apple’s commitment to long-term support for iPhones guarantees that users can benefit from new features alongside vital security updates and bug fixes.
In recent years, Apple has facilitated users’ ability to remain on their current iOS version if they aren’t ready to upgrade. For instance, when iOS 18 was launched in September, Apple also released iOS 17.7. iPhone users could choose to update to iOS 18 to access its new features or stick with iOS 17.7, allowing them to avoid potential bugs associated with the major release while still receiving essential security fixes and enhancements.
Most recently, Apple published iOS 17.7.2 and iPadOS 17.7.2 in November, which included important security enhancements. This practice ensures that users maintain the most secure experience possible, even if they opt not to upgrade to iOS 18.
