At WWDC 2026, Apple did something specific and easy to miss in the flood of Siri AI headlines: Xcode 27 now ships with a set of agent skills that Apple wrote itself. These are not a community add-on or a generic format you have to go find. They are bundled in the toolchain, they capture Apple's own guidance for modern Swift and SwiftUI, and you can export and read every one of them with a single command.
This article is about what Apple actually shipped here, the seven skills, where they live, how to get them out, and how they fit with the broader agent story in Xcode 27. If you want the high-level overview of agent-driven development in Xcode 27, that is a separate topic. Here the focus is narrow and concrete: Apple's own skills.
Why this matters
Coding agents are good at Swift in general but unreliable at the edges: brand-new APIs they have barely seen, recently deprecated patterns they keep reaching for, and platform-specific footguns. A skill is a focused bundle of guidance that fills exactly those gaps.
What changed at WWDC 2026 is that Apple is now the author. Instead of relying on the community to document, say, the newest SwiftUI APIs for an agent, Apple ships that guidance in the box. When an agent in Xcode 27 modernizes your UIKit code or audits your security settings, it can draw on instructions written by the people who built those frameworks.
