Apple released iOS 18.6 on July 29, ahead of the company’s release of iOS 26 this fall. While the next major iOS update will bring Liquid Glass and more to your iPhone, iOS 18.6 doesn’t change much on your device. Instead of new features, the update is filled with about two dozen bug and security fixes, including a patch for a flaw that could be actively exploited.
You can download iOS 18.6 by going to Settings, then tapping General. Next, select Software Update, then tap Update Now and follow the prompts on your screen.
Here’s what iOS 18.6 brings to your iPhone.
This update patches a zero-day flaw and other issues
According to Apple’s security notes, iOS 18.6 fixes about two dozen security issues and bugs. But one issue in WebKit, Apple’s in-house-developed internet browser engine used in Safari, could compromise your system and is being tracked as CVE-2025-6558.
“This is a vulnerability in open source code and Apple Software is among the affected projects,” Apple wrote in the security notes for this issue. The CVE Program, which helps identify, define and catalog cybersecurity risks, lists the severity of this issue as high.
This bug was identified by a member of Google’s Threat Analysis Group, and Google wrote on July 15 that it is aware that an exploit for this bug exists in the wild. So you should download iOS 18.6 immediately to protect your device.
Are there any new features in iOS 18.6?
After downloading and testing iOS 18.6 during the beta cycle, I found no new features or noticeable changes in the update. That’s not surprising considering Apple’s iOS release schedule over the years.
Apple announced iOS 18 at WWDC 2024 and released iOS 17.6 more than a month later in July. That update was filled with more than 30 important bug fixes and security patches, but no new features. Apple recommended that everyone download the update at the time, and it was the last major iOS 17 update before the release of iOS 18.
Apple did the same thing in July 2023 when it released iOS 16.6. When the tech giant released that update, it was focused on bug fixes and security patches. After that, the next major iOS release was iOS 17.
Apple is likely shifting gears and focusing more on iOS 26. In fact, the company has already released multiple betas of that iOS software in preparation for its fall release.
While there aren’t any new features in iOS 18.6, you should still download the update to your iPhone to take care of the security issues and bugs, especially that zero-day flaw.
iOS 18.6 release notes
