React-native Xcode build fails -> 'RCTAssert.h file not found' - react-native

Question

I did exactly the steps which are described here in the React-native getting started guide:
https://facebook.github.io/react-native/docs/getting-started.html
When I open the Project and build it, the build fails:
RCTAssert.h file not found' in MyProjectNameTests.m .
What am I missing?
Here are the steps from the getting started guide:
Requirements
OS X - This repo only contains the iOS (7+) implementation right now,
and Xcode only runs on Mac.
Xcode 6.3 or higher is recommended.
Homebrew is the recommended way to install io.js, watchman, and flow.
Install io.js 1.0 or newer. io.js is the modern version of Node.
Install nvm with its setup instructions here. Then run nvm install
iojs-v2 && nvm alias default iojs-v2, which installs the latest
compatible version of io.js and sets up your terminal so that typing
node runs io.js. With nvm you can install multiple versions of Node
and io.js and easily switch between them.
New to npm?
brew install watchman. We recommend installing watchman, otherwise
you might hit a node file watching bug.
brew install flow. If you want to use flow. We recommend
periodically running brew update && brew upgrade to keep your
programs up-to-date.
Quick Start
npm install -g react-native-cli
react-native init AwesomeProject
In the newly created folder AwesomeProject/
Open AwesomeProject. xcodeproj and hit run in Xcode. Open index.ios.js
in your text editor of choice and edit some lines. Hit cmd+R in your
iOS simulator to reload the app and see your change!

Answer 1

The test application can't find the header because it's not in the header search path.
In the left hand file list, hit the top left "folder" icon, then select your application at top left. In this case "AwesomeProject".
To the right of that, where the application icon appears, hold down to change to AwesomeProjectTests.
On the right side, click on the 'Build settings' tab.
Then scroll down to Header Search Paths and change "$(SRCROOT)/node_modules/react-native/React" to "$(SRCROOT)/../node_modules/react-native/React".
The app should now compile.

I got the same issue as daniel but I already have the right path in xcode ...
0.10.0 is my version

Answer 3

It's an issue in 0.10.0, and it has been fixed just now.
You need to re-generate your project. Refer to this PR: https://github.com/facebook/react-native/pull/2474

Answer 4

seeing same issue here and it seems react-native is latest on 0.10.0, i was using 0.8.0 and was running fine. May be to disable the test target for now?

Answer 5

Before testing any option from the above mentioned solutions, just clean your xCode and build the app again. That helped me

Answer 6

I had the same issue (I just had changed my apple ID password). I needed to redo the code signing configuration.

Answer 7

This happened to me on a React Native project.
I rolled back my code to a version that I knew built successfully and still got this error. How is this even possible? There's two hours of my life I'll never get back. I write this here on the chance I save you from the same fate.
In my case when I jump from my IDE in which I code my react-native project over to Xcode I open it from Spotlight.
At this point it is so easy to click the wrong icon on the right hand side. I accidentally clicked on the Xcodeproj file instead of the Xcworkspace. Easy to do, once it loads everything looks exactly the same, I was none the wiser.
The only indication that something had gone wrong was the build errors. Worse this error looks like a dependency management issue sending you down completely the wrong path in a resolution attempt.
This is not just a React Native specific issue, but something all Cocoapod users need to remember.

ADD the React Path to Podfile
platform :ios, '9.0'
target 'YourProject' do
...
pod 'React', :path => '../node_modules/react-native'
end
target 'RNFirebaseTests' do
...
pod 'React', :path => '../node_modules/react-native'
end
