Getting error while running clubbed swift & react-native project on iOS device

I have an existing project written on swift and I have integrated react native to it everything is working fine on simulator but while running on device it give an error ie- Could not connect to the development server. Ensure - node server is running and available on the same network - run npm start from the react native root - node server URL is correctly set in AppDelegate

I have tried most of the method discuss over here github link

• like changing the localhost to my laptop IP,
• connecting device and laptop on the same network

but still i could not able to solve it, if i am missing any things kindly enlighten on comment or answer you valuable time will always be helpful

thank you
