Describe the bug

After upgrading LiveKit Server from 1.5.1 (ServerInfo: edition=standard, version=1.5.1, protocol: 10) to 1.9.x, iOS connections using LiveKit Swift SDK 2.11.0 became unstable: sometimes the room does not connect at all, and sometimes it disconnects shortly after joining, causing publish/re-publish of local tracks to fail with connectionState is .disconnected errors.

SDK Version

  • LiveKit Swift SDK: 2.11.0 (mobile)

iOS/macOS Version

  • iOS: iOS 18.2, physical device

Xcode Version

  • Xcode: 26.1
  • Swift: 6.2.1

Steps to Reproduce

  1. Run LiveKit Server 1.9.x (previously stable on 1.5.1, protocol 10).
  2. Connect from an iOS app using LiveKit Swift SDK 2.11.0 and join a room.
  3. Start publishing local tracks, especially screen share video (ReplayKit‑based).
  4. Repeat join/leave and publish/stop cycles; intermittently, the room fails to connect or moves to .disconnected, and track publish fails with state errors.

Expected behavior

  • Stable connection to LiveKit Server 1.9.x, same as with 1.5.1.
  • Local tracks (camera/screen share) should publish and re‑publish without connectionState is .disconnected errors.

Screenshots

  • N/A
