iOS 18 introduces more customization and the first rollout of Apple Intelligence.

Apple has released iOS 18 — plus iPadOS 18, macOS Sequoia, watchOS 11, and other new updates — bringing several key updates to how the company’s devices operate and setting the stage for generative AI features.

The most discussed feature of iOS 18 is the Apple Intelligence suite. With the release of iOS 18.2 on December 11th, features that are available now include generating images in Image Playground, creating custom “Genmoji” emoji, and ChatGPT integration. Other features of Apple Intelligence, including writing tools such as the ability to rewrite your text in different styles, trickled out to customers starting in October.

There are major non-AI changes to consider too, like the ability to change your default apps or test your hearing with AirPods.

Meanwhille, iPadOS 18 now has a calculator app and can solve math equations in notes, watchOS is keeping an eye out for sleep apnea, and now your iPhone can even message Androids with RCS.
