How to Integrate react-native to iOS with separate folders. (Not inside react root directory).?

I already have a project on iOS and Android. I would like to implement some new features in react-native. I have done integration in sample apps as well and its working like a charm.

But my doubt is, this is working when I have iOS and Android code in react root directory. when I move the iOS and Android in a separate folder unable to install pod in ios. Getting error in "use_native_modules".

Working Folder Structure

But I need

I have changed the path in Podfile pointing to the react directory. When I use

require_relative '../ReactNative/node_modules/@react-native-community/cli-platform-ios/native_modulesuse_native_modules!

I am unable to install the pods. getting

[!] Invalid `Podfile` file: [!] /usr/local/bin/node -e try {console.log(require('@react-native-community/cli').bin);} catch (e) {console.log(require('react-native/cli').bin);}internal/modules/cjs/loader.js:1032 throw err; ^Error: Cannot find module 'react-native/cli'Require stack:- /Users/user/Documents/Sample ReactNative Projects/SeperateFolders/iOS/[eval]    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:1029:15)    at Function.Module._load (internal/modules/cjs/loader.js:898:27)    at Module.require (internal/modules/cjs/loader.js:1089:19)    at require (internal/modules/cjs/helpers.js:73:18)    at [eval]:1:87    at Script.runInThisContext (vm.js:131:18)    at Object.runInThisContext (vm.js:295:38)    at Object.<anonymous> ([eval]-wrapper:10:26)    at Module._compile (internal/modules/cjs/loader.js:1200:30)    at evalScript (internal/process/execution.js:98:25) {  code: 'MODULE_NOT_FOUND',  requireStack: ['/Users/user/Documents/Sample ReactNative Projects/SeperateFolders/iOS/[eval]'  ]}. #  from /Users/user/Documents/Sample ReactNative Projects/SeperateFolders/iOS/Podfile:48 #  ------------------------------------------- #    >    use_native_modules! #     #  -------------------------------------------

Also when I comment those 2 lines in pod file auto-linked pods are not getting installed.Is there any way to achieve this?or Is this the structure we need to follow?

Kindly help.

Thanks in advance.
