React/RCTDefines.h' file not found (RN0.61) - react-native

Question

Performed RN upgrade from RN0.60 to RN0.61. Build failed with iOS, due to the following issue:
/react-native/React/Base/RCTBridgeModule.h:10:9: 'React/RCTDefines.h' file not found
I am aware of this breaking changes. (React.xcodeproj is deprecated)
Try a few things
npx react-native-clean-project & re-setup project
remove Pods/ & pod install
...running out of idea...
Here's how my podfile looks like.

Answer 1

Here's my solution after spending a full day in digging the reason why,
.
.
.
.
TLDR;
You need to add .podspec to podfile for whichever 3rd party/custom library that complain unable to find React/{whatever.h}
3rd party Libraries
If you are using a 3rd party library (Yarn/NPM/etc)
Copy podspec from other 3rd party library (eg, RNDeviceInfo/etc..)
Create own podspec by replacing a few item (s.name, s.source) I actually left others as default but you can modify as per your usage if you want
s.name = "NoSupportedLib"
s.source = { :git => "https://github.com/react-native-community/NoSupportedLibName.git", :tag => "v#{s.version}" }
You might want to take care the following, because not all your dependency may store under the folder path ios/**/your.m & your.h files
s.source_files = "ios/**/*.{h,m}"
Add new line to podfile
pod 'NoSupportedLib', :path => '../node_modules/NoSupportedLib'
Pod install
Local Dependencies
In the case where you have a local dependency, you should do the same as well (instead of adding the .a file into your Xcode's Linked Framework and Libraries.)
Follow the same steps as described on top
At step 2 where you declare the s.source & s.source_files, you shall do the following: (Assumption you are create this custom.podspec at the same custom library path, you would otherwise need to modify the s.source path as your need)
s.source = { :http => 'file:' + __dir__ + '/' }
s.source_files = "customLib/*.{h,m}"
Add new line to podfile
pod 'customLib', :path => '../localDependency/customLib'
Sub-points
I tried adding React under my scheme as build target, apparently it does not help. I think for project that is >=RN0.60, we are meant to use autolinking provided by ReactNative? Hence to keep our Xcode's Linked Framework and Libraries clean.

Answer 2

I've had the same issue a while ago. It was fixed after: product > scheme > edit scheme, go to the build tab and add react as the first target.

Answer 3

I had this same issue, I went into /node_modules/react-native/React/Base/RCTBridgeModule.h and changed #import <React/RCTDefines.h> into
#if __has_include("RCTDefines.h")
#import "RCTDefines.h"
#else
#import <React/RCTDefines.h>
#endif

Answer 4

Go to Project navigator > Libraries > RNFetchBlob.xcodeproj
Click on Build Settings and then the first item under "Targets"
Scroll down to 'Search Paths' -> 'Header Search Paths'
Make sure to have enable filter 'All'
Add the following entry (click '+'): ${SRCROOT}/../../../ios/Pods/Headers
Make sure to set it to recursive.
Clean (cmd + shift + K) and re-build (cmd + B)
