The most crucial step! Enable "Wireless Debugging" on your Apple TV. On Apple TV: Go to Settings → Remotes and Devices → Remote Apps and Devices Keep this interface open. Your Apple TV will automatically enter "Waiting to Pair" mode. (A message will appear on screen: "Ready to connect using Xcode or Apple Configurator") Do not exit this screen! Otherwise, Xcode won't be able to detect the device.

【Apple TV 4K (3rd generation)】 If you have a physical Apple TV, please follow these steps: Connect the device Open Xcode → Window → Devices and Simulators Ensure your Apple TV and Mac are on the same Wi-Fi network Click the "+" at the bottom left → "Pair Apple TV" Enter the pairing code displayed on your Apple TV as prompted Once completed, your Apple TV will appear in Xcode's device list Re-enable Xcode signing Select your tvOS target Open Signing & Capabilities Check "Automatically manage signing" Select your Team (developer account) Xcode will automatically: Register com.********.tv with Apple Create a tvOS Development Provisioning Profile Bind it to the Apple TV you just connected Issue resolved – Xcode will no longer report errors.

I figured it out! When Xcode performs Automatic Signing, it: Communicates with the Apple Developer Center; Searches for registered devices under the account; Automatically generates or updates the corresponding Provisioning Profile. If there is no Apple TV (tvOS device) in the account, Xcode will fail because: Apple requires that development profiles must be bound to at least one physical device.

I wrote a separate agent module and it works fine. The combination is normal. It's normal in Xcode. Run the program to the simulator, or the real machine. There is only one agent module. The entire program cannot be displayed.

Very effective help
