pod install breaks AppCenter iOS build.

[bengtan]

Running pod install picks up some changes related to react-native-config and two (dangling?) symlinks:

ios/Pods/Headers/Private/react-native-config/GeneratedInfoPlistDotEnv.h
ios/Pods/Headers/Public/react-native-config/GeneratedInfoPlistDotEnv.h

which then cause the AppCenter iOS build to fail.

This happened in #4507 and required a work-around in #4509.

See #4509 (comment) for more information and a work-around.

I'm not sure what the exact problem is, but since it's blocking us from doing pod install cleanly, we probably need to look into it before evaluating more dependabot native PRs.

Possibly related:

• Error message error: Build input file cannot be found: '/Users/runner/runners/2.160.1/work/1/s/node_modules/react-native-config/ios/ReactNativeConfig/GeneratedDotEnv.m' (in target 'react-native-config' from project 'Pods') from https://appcenter.ms/orgs/hippware/apps/tinyrobot-2/build/branches/master/builds/3714

• Not working with RN 0.60.4 lugg/react-native-config#365

• We are using react-native-config from a specific github commit (see package.json)

Somehow, this stopped happening. Maybe as a result of updating pods in PR #4516? Dunno.

Anyway, I'm gonna leave some notes for historical reference.

Somehow/sometimes, a pod install introduces two react-native-config header files:

• ios/Pods/Headers/Public/react-native-config/GeneratedInfoPlistDotEnv.h
• ios/Pods/Headers/Private/react-native-config/GeneratedInfoPlistDotEnv.h

which are symlinks to ../../../../../node_modules/react-native-config/ios/ReactNativeConfig/GeneratedInfoPlistDotEnv.h

The iOS build fails with

• error: Build input file cannot be found: '.../node_modules/react-native-config/ios/ReactNativeConfig/GeneratedDotEnv.m'

This error occurs with a clean build, but doesn't always occur on a non-clean build.

If building on a non-clean source tree, the file may have been created by a previous build.

I speculate that GeneratedDotEnv.m is a generated file that is generated by node_modules/react-native-config/ios/ReactNativeConfig/BuildDotenvConfig.ruby which I think is an iOS build script.

It is referenced in ios/Podfile.

I speculate that ... somehow having 1 results in 3 not building 2, and then the iOS build fails.

But anyway, since this has apparently gone away/fixed itself, I'm closing.
