Your experience with Xcode agentic coding

invalid@example.com (Doctor Q) — Wed, 04 Feb 2026 10:25:14 +0000

News: Xcode 26.3 Lets AI Agents From Anthropic and OpenAI Build Apps Autonomously

Apple's demonstration makes it look amazing, and the integration between Xcode and well-known coding agents is certainly a great convenience.

But does it work for you in practice? Does it save you hours of work, as Apple promises, does it cause headaches you didn't foresee, or both?

Strange Error

invalid@example.com (Senor Cuete) — Tue, 03 Feb 2026 19:49:12 +0000

I have a project with this C code:

Code:

const unsigned long ARRAY_SIZE = 1000000;

unsigned long array[ARRAY_SIZE];

XCode posts a strange warning:

Variable length array folded to constant array as an extension

There is no warning if I remove the const declaration from the ARRAY_SIZE declaration.

What does this mean?

Looking for volunteers for GPU benchmarking

Heya,

As the rendering is very FPS-sensitive, I'm collecting GPU performance results from various Apple Silicon macos devices for the performance table here:

FireWire stack re-write

Hey community,

I didn't really find a better place to share this, so I hope it's okay to post here.

I'm working on restoring the FireWire stack on macOS "Tahoe" for Apple silicon Macs.

Here is my repo: https://github.com/mrmidi/ASFireWire

Let me keep it brief:
- It's a re-implementation of the FireWire stack using DriverKit and PCIDriverKit.
- It could potentially run on iPads one day with the right entitlements (if it ever becomes possible to get them).

How to design a simple app with BLE ?

We are now able to use Foundation Models with Swift to write AI applications. This has many advantages not least being the privacy that comes from using an on-device LLM and not needing to pass our personal information to remote servers.
