Xcode 26.4 on macOS 26.3.1 cannot pair a real Apple Watch for development. iPhone companion is visible and stable in Devices and Simulators. Watch is paired to iPhone and works normally, but Xcode shows: CoreDeviceError Code: 4 RemotePairingError Code: 1007 “The device rejected the connection request.” “Ensure the device is paired with this machine.” What I already tried: trusted Mac on iPhone re-paired Watch with iPhone reconnected iPhone by cable reset authorized computers on Watch restarted devices reopened Devices and Simulators Result: iPhone remains stable Watch is seen intermittently or stays reconnecting / rejects pairing app logic is otherwise working on iPhone side Need: steps to restore Watch ↔ Xcode development pairing without further destructive resets.
