I was in charge of live-blogging WWDC 2026 earlier this week, and keeping up with Apple’s device requirements for iOS 27, Apple Intelligence, and Siri AI felt like a job for someone with a photographic memory.

All three software packages have different entry criteria (and that’s to say nothing of iPadOS 27 and macOS Golden Gate), so after the show, I published an iOS 27 and Siri AI compatibility explainer, which will tell you whether your iPhone can support Apple’s upcoming iOS features.
