I upgraded react-native to version 0.61.2, and did rm -rf Pods, rm -rf Podfile.lock and then pod install, then open xcode with myproject.xcworkspace, click build button, I got:
'React/RCTDefines.h' file not found, my Header Search Paths is set as $(inherited) recursive, also I went to Manage Schemes ->myproject target -> Build, I unchecked Parallelize Build and I have React as my first Target before myproject.

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
I used patch-package to patch.
Hi jeffmon, thanks for your response, I am using react-native 0.61.2, the most recent version, there is no /node_modules/react-native/React folder, the new version is all pod, there is a React.podspec as attached picture shown, so what to do? thanks again for your help.



I'm using RN 0.61.2 as well, here is what my node_modules/react-native folder looks like. Try rm -rf node_modules and yarn install again.
Thanks for your help, after I rerun npm install for react-native, I got the React subfolder, now it passed the React-Core build, but I got another issue with react-native-svg:
'React/RCTImageLoader.h' file not found:

I have RN 0.61.2 and "react-native-svg": "^9.11.1"
I did fresh pod install with react-native-svg pod, also It was mentioned here that RCTImageLoader.h is removed from RCTImage:
https://github.com/pilot4u/react-native-fs/pull/1/commits/05097bcfd8877a195d1a3734ac1565aa13fea19f
So what is the solution?

Sorry for the late response, but you might have to run a similar if/else block in RNSVGImage.m.
im having the same issue but only on other build scheme than the original one. it cannot find many
btw i also have react native 0.61.2
I found a solution for this problem, see here https://github.com/joltup/rn-fetch-blob/issues/461#issuecomment-553355501
I haven't upgraded RN, currently have a version 0.61.5. I installed the package using npm and added pods. And I am getting mentioned error while trying to create the build, should I go through manual linking steps at all or not? @infostreams I have tried your solution in the comment and I got this

@judygab No idea. I had this issue 5 months ago, spent a day cursing at it until I fixed it as described, and then didn't look back 😬 Sorry! And good luck.
fwiw, this issue bubbled up to me when I manually linked a package that didn't contain a podspec. Maybe useful here? 🤷♂️
