Apple’s latest iPhone software, iOS 26, is now on general release. iOS 18.7, also just released. Apple usually runs the two versions in parallel for maximum two months, to give the cautious time to get used to what’s new. Staying off iOS 26 for now may also be appealing if you don’t care for the signature update: Liquid Glass. This has been warmly received but not universally liked. Still, be warned, you will have to update sooner or later if you want full security protections. iOS 18.7 is for all iPhones from 2018 onwards. That means the iPhone Xs, iPhone Xs Max and iPhone XR and all iPhones since, including the iPhone SE in both its second- and third-generation models. And all members of the iPhone 16 series are included, right up to the iPhone 16e. Note that iOS 26 is available to all of these phones except the first three. It’s compatible with iOS 11 and onwards. Apple is tight-lipped about what’s in iOS 18.7, merely saying “This update provides important bug fixes and security updates and is recommended for all users.” It hasn’t yet updated with full details of exactly what bugs have been squished and usually releases details of security concerns later, when users have had a chance to update to protect themselves.
