If you recently installed/updated Xcode, make sure you install command line tool.

Xcode and the GDB connection is quite temperamental. The device and your Mac can become unsynchronised with each other. My checklist for this sort of thing:

  1. Restart Xcode.
  2. Delete the .app from your iOS device, do a Clean then Rebuild.
  3. Disconnect, reconnect device.
  4. Restart iOS device (90% of the time it fixes things)
  5. If all else fails, restart your Mac (unlikely but it did fix an issue once for me).

From question: Error : The service is invalid

  • Or please check your iphone and xcode update version of OS!

Do you sign in with your dev account with xcode? Example image given below: enter image description here

You can try also with network connection: https://i.sstatic.net/VLwMY.jpg

Finally, I figure it out how to solve it. I have two iPhones, one is running iOS 11.2.2. It can be detected in Xcode 9.2. Another one running iOS 11.2.6 can't be detected in Xcode 9.2. I tried all the solutions above, it still not work. After I upgrade the iPhone running iOS 11.2.2 to iOS 11.2.6. When I connect this iPhone to Mac, Xcode take a little while on "preparing debugger support on iPhone". Then anything just works fine. All devices can be connected in Xcode 9.2. It seems some conflicts occur between two different devices running different iOS minor versions respectively.

Anyway, thanks to everyone who give me suggestions. Many THX!!!

In Xcode 9 and above you can run app without connecting it to mac.

  1. First set the device lock in iPhone.
  2. Then connect it to xCode and go to Window -> Device and Simulators.
  3. Select your device from left side list and check Connect via Network checkbox.
  4. Then disconnect the device and Go to settings and Enable Network sharing from Sharing setting.
  5. Connect your iPhone to wifi of your mac and run the app.

It will work in Xcode 9 and above.
