From my years of iOS development—and based on https://xcodereleases.com typically ships two major Xcode updates each year:
- X.0 (September): bumps Swift, SDK versions, etc. It also tends to have a noticeably longer beta cycle than other releases.
- X.3 or X.4 (around March): bumps Swift again and raises the minimum required macOS version.
Other releases in between are usually smaller updates that add features or fix bugs, but they don’t involve major toolchain-level or fundamental changes.
Today’s release doesn’t bump the Swift version, which suggests the core toolchain is essentially the same as Xcode 26.2—so it makes sense that the minimum macOS version wasn’t raised either.
Agreed - I tried installing Xcode26.3 on my mac running Sequoia and there's no "intelligence" pane in Xcode settings to connect Claude like there is in the docs.

I think it is required for any AI support. Xcode will run with limited features on earlier OS's.
