iOS 18 adds Apple Intelligence, customizations, and makes Android SMS nicer

The biggest feature in iOS 18, the one that affects the most people, was a single item in a comma-stuffed sentence by Apple software boss Craig Federighi: "Support for RCS."

As we noted when Apple announced its support for "RCS Universal Profile," a kind of minimum viable cross-device rich messaging, iPhone users getting RCS means SMS chains with Android users "will be slightly less awful." SMS messages will soon have read receipts, higher-quality media sending, and typing indicators, along with better security. And RCS messages can go over Wi-Fi when you don't have a cellular signal. Apple is certainly downplaying a major cross-platform compatibility upgrade, but it's a notable quality-of-life boost.

Apple Intelligence, the new Siri, and the iPhone

iOS 18 is one of the major beneficiaries of Apple's AI rollout, dubbed "Apple Intelligence." Apple Intelligence promises to help iPhone users create and understand language and images, with the proper context from your phone's apps: photos, calendar, email, messages, and more.
