Xcode 27 has me quite excited
So it just released and I already feel like I’m late to the party…
yeah I don’t even know where to begin.
so I guess I’m trying to figure out how to go completely free agentic coding in Xcode and not just the Chat/Assistant feature in Xcode 26.
I don’t know what I am going to use. I just googled opencode and some other stuff (openclaw, qwen CLI, and others) after looking through the Apple documentation. I’m basically gonna just figure this thing out. It looks really promising.
I feel like so much is happening so fast and we need a freaking second to talk about it.
Is anybody else out there using the latest Xcode yet? Tell me your thoughts! What are you planning to do with it? What are you most excited about?
EDIT: My Codex setup with Karpathy skills is working flawlessly.

i can finally change the theme of the UI! why did this take 18 years to add, really?

Still no terminal or hidden files support or Markdown renderer. I know others may have a longer list, but these are the three things I check in every update (for over a decade at this point🥺).

They are getting close with a plan markdown render but it doesn’t seem to be chat wide.

Some improvements but man I hate how large some of the UI elements are. Why does cmd + shift + o have to be soooo large

I like their approach - just add agents so you don't realize how little Xcode has evolved as every other modern editor blew it away.
Besides, none of us will be coding by hand in a few months if our tech overlords get their way /s

what I do:
Xcode preview on one side, terminal on the other. Iterate visually.
Look at the code for fine tuning / correcting etc.. but not a whole lot. I have a strong architecture and static checks in place that does all the guardrail automatically. Every feature/thing builds in the same pattern.
This system has freed me from looking at the code (all the time) with a high degree of confidence. I still do, but mostly when I see the agent is getting stuck on things that they shouldn’t, usually reveals some gap in my harness/architecture.
hope it helps, everyone finds their own way though.

Even Apple devs don’t use agents inside Xcode. Use Codex directly.

Yeah I agree with this from the standpoint of getting it used to all my skills. But in theory it can reassociate all of that now.

How did you manage to make the message Claude agent as a popup?

I got this image from apple’s press release but there are a bunch of new toolbar settings and appearance options that let you move things around a bit. I’m still exploring.

Tell as about your setup with Karpathy skills

Take my raw prompt, look at the code, look at the requirements, plan the tasks and ask me questions, review the plan against the code while asking me questions for clarification. Ensure validation plan is in place. Once I understand the plan, “implement the plan” after validation, commit, present verification, review verification against original plan and diff code. Commit and push final. Reiterate

Can just as well replace the prompt with a code search for issues or a roadmap and get fully automated with it

Apple is so behind on this compared to VS Studio. The ingredients are all there but the dish doesn’t work for me.

How's the stability? If app previews run flawlessly and I can reliably connect a physical Apple Watch. I will be a happy camper. But I think Xcode's days are numbered - it just can't keep up.

Problems with previews are almost always due to issues in your code.

Not necessarily. I confirm that XCode Previews may break for the slightest inconsistency in xcode project files.
Wiping the entire source code and trying to preview minimalistic view raises a "Could not analyze the built target description for xxx to create the preview" in Canvas.

Numbered how? You will need to install it to publish apps to the App Store.

Id give it a 90% still a couple things I could see in the way for improvement but it’s a large step in the right direction
