Changes only propagate if I remove derived data

[ToshKoevoets]

Every time I rebuild with different .env values in the IOS simulator I have to delete deriveddata, which makes rebuilding slow; also takes a long time for developers to figure out, hence bunch of issues saying it either doesn't work, have to run pod install etc.

rm -rf ~/Library/Developer/Xcode/DerivedData

i just run into the same problem, is this a new? I had the impression it worked before without deleting derivedData

Same issue, initially suspected it might be related to our project. However, after testing 'Example/0.68.5', it appears the issue is not project-related.

I have added the script to delete the build cache before every building

This works file!!

For prod it's a good idea, for dev would make it unnecessarily slow

I'm having the same issue, but fixed it in suggested way on deleting rn-config cache.

Question is, do you know why this is happening?

[januswel]

@uwbobanminic

react-native-config generates a native-readable source file for each platform, before building

• iOS
• Android

That's why deleting the cache works so well

I think it would be good to add a comparison the last modification time of .env and the one of the last build, and regenerates if those are different

ToshKoevoets macrozone januswel uwbobanminic midrizi The easiest way for now is to add script rm "${SRCROOT}/../node_modules/react-native-config/ios/ReactNativeConfig/GeneratedDotEnv.m" This will not hamper your derived folder

Just add this script inside build phase click + and then New run script phase ->> Then add The above line but make sure to place the script at top of every one

if you have multiple Targets then add in each target Build phase same script Attaching screen shot reference

Please, how can this be done for Android?

In my experience i need to clean my build everytime i switch to another scheme before running it on the device using XCode. Sure this slowing down the build time significantly.

[7dp]

But if i run the app through the cli without cleaning the build then it works. I don't to need to clean the build everytime i switch between scheme. I run it like this:

ENVFILE=.env.production react-native run-ios --scheme 'YourProdScheme'

So for now i always run the ios app through the cli and doesn't therough XCode.

Hope it helps someone, thanks.
