iOS 18.6 delivers vital security patches, resolves the Photos sharing glitch, and brings EU-friendly app-store changes. Learn why updating your iPhone today keeps it safer and smoother.

What Is iOS 18.6, and Why It Matters

iOS 18.6 is Apple’s latest iPhone software update, released on July 29, 2025, and while it may seem like a small release, it carries big importance. Designed primarily as a stability and security-focused update, it delivers 24 critical security patches to protect users from active threats, including a dangerous WebKit zero-day exploit. It also fixes a frustrating Photos app bug that stopped memory movies from being shared, restoring one of the iPhone’s most loved creative features. For European Union users, it introduces a major change by allowing apps to be installed from alternative marketplaces or directly from developers’ websites, in compliance with new regulations.

Bolstering iPhone Safety: Security Fixes You Can’t Ignore

iOS 18.6 is a must-install update because it addresses some of the most urgent security vulnerabilities found in recent months, making your iPhone significantly safer. Apple has patched 24 critical issues, including a dangerous WebKit zero-day flaw (CVE-2025-6558) that was already being exploited by attackers through Safari and apps using the browser engine. Other fixes close loopholes that could allow address bar spoofing on malicious websites, prevent privacy indicator bypasses for the microphone and camera, and stop a VoiceOver bug that could read your passcode aloud. These aren’t theoretical problems—they’re real risks that could expose personal data, financial information, and private conversations.

Fixing the Annoying Photos Bug

Alongside security improvements, iOS 18.6 resolves a more visible but annoying issue: a glitch in the Photos app that interfered with sharing memory movies, the short videos Apple automatically creates from your photo library .

If you ever tried to send a memory video and it failed, this update ensures that sharing works again—without fuss.

European Users: A New App Store Landscape

Transitioning from stability to regional changes—iOS 18.6 introduces big changes for EU users.

In a move mandated by the Digital Markets Act, iPhone users in the European Union now gain the ability to install apps from outside the official App Store, whether directly from developers’ websites or from approved alternative app marketplaces .

Final iOS 18 Update Before a Big Overhaul

Putting all this in context, iOS 18.6 is likely the final minor update in the iOS 18 cycle. Apple has already shifted attention to its next major version, iOS 26, expected this fall with fresh features and a complete naming overhaul—from incremental numbers to year-based labels 

So think of iOS 18.6 as a tidy wrap-up—closing security gaps, refining usability, and paving the way for what’s next.

Step-by-Step Guide: How to Update to iOS 18.6

Updating to iOS 18.6 is quick and straightforward. Begin by opening the Settings app on your iPhone, then scroll down and tap General. Next, select Software Update, and your device will check for the latest version. When iOS 18.6 appears—with the build number 22G86—tap Download and Install. If prompted, enter your passcode and agree to the terms and conditions. The update will start downloading, which may take a few minutes depending on your internet speed.

What to Do After Installing iOS 18.6

After installing iOS 18.6, it’s a good idea to take a few quick steps to make the most of the update. Start by testing the Photos app to confirm that memory movies now share correctly, since that bug has been fixed. If you’re in the European Union, you may also want to explore the new option to install apps from alternative marketplaces or directly from developers’ websites. Check your battery performance and overall device stability—many users have reported smoother performance and longer battery life, especially on older iPhones.

Community Voices: What Real Users Are Saying

Real-world feedback on iOS 18.6 shows that many users see it as one of the most stable updates in the iOS 18 cycle, with some praising it for fixing long-standing issues like the black viewfinder bug in Snapchat and other third-party camera apps, as well as reducing overheating problems. Reddit discussions highlight that “.6” updates are often the most reliable each year, making this release a safe bet for performance. However, not everyone is completely satisfied—some have noticed changes to sound settings, such as alarm volume now being controlled only through “Sounds & Haptics,” which removes the ability to adjust volumes for individual apps.

Why iOS 18.6 Should Be Your Next Update

iOS 18.6 should be your next update because it delivers a powerful mix of urgent security fixes, essential bug repairs, and forward-looking improvements that keep your iPhone safe and running smoothly. This release patches 24 security vulnerabilities, including a dangerous WebKit zero-day exploit already being used by attackers, ensuring your personal data, passwords, and online activity stay protected.
