AppleX4Xcode 27 trae Gemini integrado nativamente. Ahora developers tienen Gemini, Claude y Codex en el mismo lugar... pero ¿necesitan realmente tres IAs agénticas o es solo ruido de la industria tech? 🤔 #Xcode27 #AppleX4
Michael RoweOk, I have been looking for how to setup an agentic server locally in my HomeLab. Now that I see Xcode allowing for pointing to a local ACP Agent, this increases the need. I am looking for any good sites that can help me setup this up on macOS. #agenticai #homelab #xcode27
Taylor ArndtWe had been banging our heads on this for a couple of days, and this morning it finally clicked. You can use ACP inside Xcode 27, which means our Hermes agent can code right inside it. @mikedoise figured out the piece that got us there.
Florian HeidenreichFYI, installing #Xcode27 beta broke the ability to create VMs on my installation of macOS 26.5.1. Tried UTM and VirtualBuddy.
I had to install the #macos27 beta on a dedicated APFS volume, was able to create the VM there, and copy it over to my production install.
According to an Apple Engineer, it’s a “late incompatibility between the VZMacOSInstaller API on macOS 26.6 and the macOS 27 IPSW”.

EmreI'm really scared when I first saw Xcode 27's default theme (especially the purple color🤮) hopefully they put an option to select Xcode 26 easily 😮💨

Really? Oh yes! They finally changed Cmd + R in the “simulator”, so there’s no more accidental recording!
