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).
