Wow. Nice list of devices in an Xcode Multiplatform app template. I'm happy to see that VisionOS (Apple Vision) is in there as well. 🥽

The Claude terminal command here is on a project basis. You might want to move it to be global. You can do so in .claude.json

Is anyone else having Xcode 26.3 agent issues? I keep getting: MCP client for `xcode` failed to start: MCP startup failed: handshaking with MCP server failed: connection closed: initialize response. I can't get it to work with Claud or Codex.

Are there any details on how the new Xcode 26.3 uses Agents/Claude.md files, agents, skills, or referencing documents outside of Xcode?

A surprisingly ambitious feature for a mid-cycle Xcode update.
I'd love to see Apple further decouple feature updates from their usual yearly cycle when possible.
For AI workflows, in particular, a major feature release once a year is just way too slow.

I’m seeing a ton of CPU usage in the Xcode 26.1 RC simulator. A "ReportCrash" process shows is in activity monitor, and I see a “MercuryPosterExtension" constantly crashing via the Console app (maybe that's the name of the wallpaper app?).
Anyone else having problems?
