Review comments at @DeviceKitTests/XCTestServer.swift:
- Around line 109-125: Update the task-group handling in start() so a failure
from any HTTPServer.run() cancels sibling listeners and propagates the original
error. Consume child results with group.next() and call group.cancelAll() before
rethrowing; retain normal completion behavior when all listeners stop.

09bbb22 should address those potential issues, although I was not able to reproduce the theoretical failure case. |
…EN_HOST The JSON-RPC server built its address with .inet(ip4:), so any IPv6 DEVICEKIT_LISTEN_HOST failed at startup with inet_pton AF_INET and the runner exited before the server started. It also bound a single address, so binding anywhere else meant giving up 127.0.0.1. DEVICEKIT_LISTEN_HOST now takes a comma-separated list of IPv4/IPv6 literals and starts one listener per address with the same routes, using .inet6(ip6:) for IPv6. /shutdown stops every listener, and a bind failure on any address fails startup as before. Unset, it still binds 127.0.0.1 only, so existing IPv4 clients are unaffected. This lets DeviceKit also bind to the Xcode CoreDevice tunnel address, which reaches a real device over Wi-Fi from the paired Mac only, with no USB port forwarding. Verified: - Simulator, unset: 127.0.0.1 serves, [::1] refused, /shutdown exits. - Simulator, "127.0.0.1, ::1": device.info on both; /shutdown via [::1] stops both listeners. - iPad Air (iPadOS 26.7), USB unplugged, "127.0.0.1,<tunnel>": device.info and device.screenshot over the tunnel.
Consume the listener task group with next() and cancelAll() on the first error so a failed bind cannot leave other listeners running and hang startup. Drop exact duplicate DEVICEKIT_LISTEN_HOST entries, and document makeServer and configureRoutes.
