Xcode Coding Assistant closes connection with AI server automatically after 5 minutes

I'm trying to use Xcode Coding Assistant connected to local AI server, but the chat fails after 5 minutes with error: The request timed out. Detail: No Data/Bytes for request: http://localhost... AI server gives me info that client disconnected:

2026-10-19 22:24:23  [INFO]

It looks like http/tcp default timeout. AI suggests that it should be possible to set Xcode Coding Assistant timeout, but I cannot find it anywhere.

How is Xcode Coding Assistant supposed to work if it shuts down on default network protocol timeout?

I haven't tried yet on nVidia hardware, which should be faster, but it could still be a problem when working on multiple files in project with inference running on one Blackwell chip. I do not have nVidia rack with 72 chips, it wouldn't fit to my home office.

How do I change the network timeout for Coding Assistant?

Configuration: MacOS 27.0.1 (26A434) Xcode 27.0

Forget Xcode for AI coding! Just downloaded LM Studio Bionic and it works like charm. This is how agentic AI should really work. Apple still has to learn about AI.
