Variable are UNDEFINED on IOS

[Antholife]

I use:

• "react-native": "0.72.7"
• "react-native-config": "1.5.1",

When I log my variables they are undefined, I've come to find you because I haven't been able to solve the problem for a few days.

I don't use EXPO.

My .env:
API_ENDPOINT=DEVELOPMENT_PHYSICAL

My react-native.config.d.ts:

declare module "react-native-config" {
export interface NativeConfig {
API_ENDPOINT:
| "DEVELOPMENT"
| "DEVELOPMENT_PHYSICAL"
| "PRODUCTION"
| undefined;
}

export const Config: NativeConfig;
export default Config;
}`

In my file:
import { Config } from "react-native-config";
const { API_ENDPOINT } = Config;

console.log(Config.API_ENDPOINT);
console.log(API_ENDPOINT);

LOG undefined
LOG undefined

hey, did you find a way to make it work?

[justincounts]

I think I am seeing this as well

[sa-ma]

I've been having this issue for weeks, still no solution in sight.

Hi @Antholife

You are importing in the wrong way

it should be import Config from "react-native-config";
and not import { Config } from "react-native-config";

Hi,

I've already tried both, which is not the problem, and it's valid.

And some people have the same problem

declare module 'react-native-config' {
export interface NativeConfig {
HOSTNAME?: string;
}

export const Config: NativeConfig
export default Config
}

Same issue here

"react-native-config": "^1.5.1"
"react-native": "0.72.7"

Not sure if this was a long-running user error on my part, or something changed in react-native-config, but I determined that the shell script I was using to generate .env files during builds was running after the part of the xcode build that looks for the files.

I ended up moving this process from a Build Phase into a pre-build action and my issue was resolved.

[dan-iliescu]

Could you please tell us what you have changed explicitly? Like what is the section of the shell script that loaded up the vars?

The Shell Script was invoked as part of a Build Phase Script

However these scripts were running after Pod were compiled, the .env file was generated after react-native-config's build process looked for it.,

I instead invoke the script in a Pre-Build Action

i solved the promblem by this issue on stackoverflow

[edwinwong90]

Is works for me, this is my RN version

- react-native: 0.74.1
- react-native-config: ^1.5.1

At first, I was encounter the same issue undefined in ios. It works after I "Clean Build Folder". It could be cache issue. Is better try following :

• Clear Metro Cache
• Clean Build Folder
• Clear Xcode Cache

Hope it works for you!

[valerii-link]

Why?
Currently Xcode doesn't know about .env changes, therefore always rebuilding with cached data.

Temporary workarounds:

1. Clean/Rebuild on EVERY .env change:
   • Xcode -> Product -> Clean Build Folder OR rm -rf ~/Library/Developer/Xcode/DerivedData in your terminal
   • Build/Run you project

2. Update "[CP-User] Config codegen" at Build Phases for Pods/react-native-config target:

3. Patch node-modules/react-native-config/react-native-config.podspec:
   • Patch react-native-config.podspec file with next fix
   • cd ios && pods install
   • Build/Run you project
