The beta-testing cycle for Apple's latest operating system updates is in full swing—earlier this week, the third developer betas rolled out for iOS 18, iPadOS 18, macOS 15 Sequoia, and the rest of this fall's updates. The fourth developer beta ought to be out in a couple of weeks, and it's reasonably likely to coincide with the first betas that Apple offers to the full public (though the less-stable developer-only betas got significantly more public last year when Apple stopped making people pay for a developer account to access them).

Many of the new updates' features are present and available to test, including cosmetic updates and under-the-hood improvements. But none of Apple's much-hyped Apple Intelligence features are available to test in any form. MacRumors reports that Settings menus for the Apple Intelligence features have appeared in the Xcode Simulator for current versions of iOS 18 but, as of now, those settings still appear to be non-functional placeholders that don't actually do anything.
