Apple has released iOS 18.6 bringing 29 security fixes and a warning to update your iPhone now.
Aside from the security updates, iOS 18.6 fixes a small bug in Photos that could prevent memory movies from being generated.
For customers in the EU, iOS 18.6 includes a new user experience when customers attempt to install an alternative app marketplace or install apps directly from the web.
This is due to the fact that Apple is rolling out new App Store guidelines and a new user experience for those in the EU, in an attempt to comply with the EU’s Digital Markets Act (DMA).
