Apple's dual update: Why you might see both iOS 18.7 and iOS 26 as an option

Apple has offered users a choice with the release of two iPhone operating system updates: iOS 18.7 and the brand-new iOS 26. This dual rollout, launched on September 15, 2025, serves different user needs, ranging from stability and security to embracing a full redesign with fresh features.

What is iOS 18.7?

iOS 18.7 focuses on delivering important security patches and bug fixes without introducing any major changes in design or user interface. It is essentially a continuation and refinement of the iOS 18 experience, aimed particularly at users who prefer a more stable and safer operating system without the risks that sometimes accompany brand-new software versions. The update is lighter in size, about one-fifteenth the size of iOS 26, making it quicker to download and install. It is compatible with iPhones from the 2018 era, specifically the iPhone XS, XS Max, and XR models, up through the latest releases like the iPhone 16 series.

Features of iOS 26

In contrast, iOS 26 introduces a comprehensive redesign known as the "Liquid Glass" interface, featuring a more transparent, glass-like visual aesthetic applied throughout the operating system and first-party apps. This update also boasts new customisation options for widgets and the lock screen, enhanced camera controls, and AI-powered features aimed at boosting productivity and user experience. However, its larger size and extensive changes mean users should expect a longer download time and potentially encounter early-stage bugs common with major OS releases. iOS 26 supports newer iPhones, including the iPhone 11 and beyond, but excludes the iPhone XS series and XR.

Why Offer Two Versions?

Apple's simultaneous release ensures that users who want cutting-edge features and a fresh look can upgrade to iOS 26 right away, while those who value system stability, security, and a conservative user experience can opt for iOS 18.7. Apple plans to support both versions for approximately two months before eventually encouraging everyone to move to iOS 26 for ongoing updates and security.

How to Choose and Install

Updating is straightforward through the iPhone's Settings app under Software Update, where both iOS 18.7 and iOS 26 appear as options. Users should consider their device model, appetite for new features versus the need for stability, and willingness to troubleshoot possible bugs when choosing their update path.

Conclusion

Apple’s rollout of iOS 18.7 alongside iOS 26 provides a unique choice, emphasising security and stability versus innovation and new design. For those with older devices or who prefer a tested and trusted system, iOS 18.7 is an excellent stopgap. On the other hand, iPhone users eager for the latest interface and features will find iOS 26 to be a compelling upgrade.
