Hello, I am experiencing a critical blocking issue developing a watchOS app. While the iPhone 15 Pro Max is fully "Connected" via USB (confirmed green light in Network Settings), the Apple Watch Series 7 (watchOS 11.2) remains unreachable by Xcode. Mac: Mac Mini (macOS 15/16). Devices: iPhone 15 Pro Max (iOS 18+), Apple Watch Series 7 (watchOS 11.2). Xcode: 16.4 / Build 26.4. Hardware: Direct USB-C connection (USB 2.0 480Mb/s protocol). Technical Evidence of Protocol Failure: Missing Staging Folders: ~/Library/Developer/Xcode/watchOS DeviceSupport does not exist, implying the handshake fails before symbol stripping/sync begins. CoreDevice Error: Consistently receiving: "Previous preparation error: A connection to this device could not be established.; Timed out while attempting to establish tunnel using negotiated network parameters." Missing Keychain Entries: No com.apple.coredevice keys found in Keychain Access, suggesting the Trusted Host handshake is incomplete. mDNS/Discovery: xcrun devicectl list devices shows the iPhone as connected but the Watch as available (paired). Steps Taken (Zero Success): Wiped ~/Library/Developer/CoreDevice and killed remoted. Disabled "Location Simulation" in Scheme Options. Reset "Location & Privacy" on iPhone; trusted Mac on both devices. Disabled Wi-Fi on all 3 devices to force Bluetooth/Wired relay. Performed "Offload App" on the iOS Watch app to reset the daemon. The "Developer Mode" toggle is missing from the Watch's Privacy & Security menu and refuses to reappear despite successful iPhone-to-Mac connectivity. Logs: I have a full sysdiagnose (300MB) ready. (Feedback ID: FB22425709). Does anyone know a specific defaults write command to force-trigger the watchOS CoreDevice tunnel or a way to manually inject the Developer Mode profile?
