I am creating a React Native module as a wrapper for existing Android and iOS libraries. The Android library is a jar file and the iOS library is xcframework file. I put the xcframework file inside the ios folder, and the jar file inside android/libs folder ( I created the libs folder). I first tried the iOS library by adding s.preserve_path, s.xcconfig and s.vendored_framework inside the project level podspec file. I am not sure if I need to do anything for the pod spec file, like running it. So I just went along with the next step by trying to import the library's .h in .m file. I tried both using angle brackets <> and using quotes "". But none worked, because firing "react-native run-is" gave me this error: fatal error: file not found. Any help on how to include the libraries in react native is greatly appreciated.
For creating react native wrapper or node module you need use below library.
https://www.npmjs.com/package/react-native-create-library
https://github.com/brodybits/create-react-native-module
Using this library you can create empty react native module project after that you can bind your native code ARR or framework files into that project.
I was able to fix the error by doing the following two steps:
Change "s.vendored_framework" to "s.vendored_frameworks" in the project level .podspec file. My original one is singular (framework), not plural (frameworks).
cd iOS && pod install && cd ..
Step 2 can be found in create-react-native-module's GitHub link:
https://github.com/brodybits/create-react-native-module
I missed the second step when posting my question. I thought then that if I ran "react-native run-ios", it would run "pod install".

I have been trying to use "React-Native-FS" while developing a react native application. However, whenever I try to import "React-Native-FS" to my app I get the following message:
Invariant Violation: Native Module Cannot Be Null
Does anyone have any clue what could be causing this? I've searched around and can't find an answer. Any help would be greatly appreciated. Thanks!
try to do link your library with
react-native link react-native-fs
if its not linked try to do manually linking with below step
ANDROID
... 1. android/settings.gradle
include ':react-native-fs'
project(':react-native-fs').projectDir = new File(settingsDir,'../node_modules/react-native-fs/android')
2.android/app/build.gradle
dependencies {
implementation project(':react-native-fs')
}
ANd do build android project with android studio
IOS
Adding with CocoaPods
Add the RNFS pod to your list of application pods in your Podfile, using the path from the Podfile to the installed module:~~
pod 'RNFS', :path => '../node_modules/react-native-fs'
Install pods as usual:
pod install
Adding Manually in XCode
In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name] Go to node_modules ➜ react-native-fs and add the .xcodeproj file
In XCode, in the project navigator, select your project. Add the lib*.a from the RNFS project to your project's Build Phases ➜ Link Binary With Libraries. Click the .xcodeproj file you added before in the project navigator and go the Build Settings tab. Make sure 'All' is toggled on (instead of 'Basic'). Look for Header Search Paths and make sure it contains both $(SRCROOT)/../react-native/React and $(SRCROOT)/../../React - mark both as recursive.
Run your project (Cmd+R)
I tried to build a react native app for iOS and I hit this error:
Build system information
error: Multiple commands produce '/Volumes/Data/sources/react-native/test/ios/build/test/Build/Products/Debug-iphonesimulator/test.app/Zocial.ttf':
1) Target 'test' (project 'test') has copy command from '/Volumes/Data/sources/react-native/test/node_modules/react-native-vector-icons/Fonts/Zocial.ttf' to '/Volumes/Data/sources/react-native/test/ios/build/test/Build/Products/Debug-iphonesimulator/test.app/Zocial.ttf'
2) That command depends on command in Target 'test' (project 'test'): script phase “[CP] Copy Pods Resources”
You can try deleting the build folder in ios directory and rebuilding your app again. It might solve this issue
It looks like you have installed some library with fonts that iOS don't have linked. Try this:
Create an empty dir in your project to store some future useful fonts (for example "Nunito" family font). I suggest create fonts folder into assets --> assets/fonts
Create a new file named react-native.config.js in the root of your project and add into it the following:
module.exports = {
project: {
ios: {},
android: {}
},
assets: ['./src/assets/fonts/'],
};
In your project dir run react-native link
Go to ios dir (cd ios) and run pod update
Build

I had this error with react-native-vector-icons installed after I executed react-native link. My solution was to remove fonts copying from XCode Build Phases.
I am trying to implement PushNotificationIOS with a detached Expo app. I am running SDK 21.0.0 (React Native 0.48).
I am getting React/RCTEventEmitter file not found
I have completed the following steps:
Open my .xcworkspace project
Drag the RCTPushNotification.xcodeproj into my Libraries folder
Added libRCTPushNotification.a into App > Build Phases > Link Binary With Libraries
Added $(SRCROOT)/../node_modules/react-native/Libraries under Header Search Paths - I also tried without the /../. I have a bunch of Pods in the Header Search Paths list too.
I then added the following into AppDelegate.m but when I click through to the file (⌘ + click), I get a question mark.
#import <React/RCTPushNotificationManager.h>
If I change it to the below, it works, I can click through
#import "RCTPushNotificationManager.h"
However, this is my problem
When I clean and build my project, I get the below error in RCTPushNotificationManager.h to say:
'React/RCTEventEmitter.h' file not found
#Dan I have ran into this exact same issue, it also occurs for RCTLinking, and other libraries dependent on eventEmitter.h and a detached Expo project.
The issue turns out to be that RCTPushNotification doesn't have the reference to React from Cocoapods file React since Expo manages React in Cocoapods. So you should go into RCTPushNotification.xcodeproj then into Targets - RCTPushNotification Header Search Paths and add the link to "ios/Pods/Headers/Public/React" and set to recursive.
The easiest way to do the above is navigate to your iOS/Pods/Headers/Public/React and drag and drop the folder straight into build settings for header search paths like the below image.
Heads up finally after this you will have to reference ReactCommon/yoga most likely as well, ReactCommon/yoga however should be in your 'node_modules/react-native/ReactCommon/yoga'
This works for me on detached Expo project
"react": "16.6.3",
"react-native": "0.58.6",
Add 'RCTPushNotification' to your pod and run pod install
pod 'React', :path => '../node_modules/react-native', :subspecs => [
'RCTPushNotification',
]
Since nothing mentioned above worked for me, I started experimenting, and this is what solved it for me:
1. Link React-Core & Public
As mentioned by Escamilla, in xcode open the RCTPushNotification.xcodeproj and under Build Settings search for header search path and add there the 2 path:
"$(SRCROOT)/../../../../ios/Pods/Headers/Public"
"$(SRCROOT)/../../../../ios/Pods/Headers/Public/React-Core"
2. Copy RCTPushNotificationManager.h manually into React-Core
In the root folder of your project execute:
cp ./node_modules/react-native/Libraries/PushNotificationIOS/RCTPushNotificationManager.h ./ios/Pods/Headers/Public/React-Core/React
This will copy RCTPushNotificationManager.h wich is in node_modules/react-native/Libraries/PushNotificationIOS/ manually into the React folder which is in ios/Pods/Headers/Public/React-Core/React.
I have no idea if that is a good solution but it works. Maybe if someone could explain me why it was not in there in the first place? That would be golden.
I followed the setup instructions 1 by 1 very carefully doing everything right but nothing worked except the manual copy mentioned above…
Also, this is randomly resetted once in a while and has to be done again -.-'
Open up your project in XCode.
Open up the Libraries folder. You should see React.xcodeproj and several RCT*.xcodeproj.
Drag the React.xcodeproj into each of the other projects.
Click on each project and navigate to the Build Phases tab.
Click on Target Dependencies and add React as a target dependency
Just follow these steps:
create project react-native init project.
add this line to pod file in ios folder: pod 'React-RCTPushNotification', :path => '../node_modules/react-native/Libraries/PushNotificationIOS'
cd ios && pod install
cd .. && react-native run-ios
No need to do messy manual linking
Replace #import RCTEventEmitter.h or #import React/RCTEventEmitter.h with #import <React/RCTEventEmitter.h>
Its work for me
this worked for me!
add the missed lib manually
https://github.com/microsoft/react-native-code-push/issues/1565#issuecomment-489738672
USE those libraries:
https://github.com/zo0r/react-native-push-notification
https://github.com/react-native-community/react-native-push-notification-ios
follow step by step,
everything will work
no need anything else
not forget to
pod install
Let's say I initialize a project under react-native init <filename>, installed a bunch of node packages, and added code.
Then separately I initialize a different project under react-viro init <filename>, installed a bunch of node packages, and added code.
If I wanted to combine what I created under react-native init into what I created under react-viro init, is it as simple as copying files over and reinstalling missing node packages into the react-viro project?
Assuming you are working in the ./src folder, every file is independent of iOS or Android as part of the JavaScript bundle.
You can simply copy the .js files over and install the node packages in that project.
You probably should not copy any files that are outside the ./src folder, but I also suspect you wouldn't need to. Files in the Android and iOS folders are rarely touched as they contain operating system config settings and custom modules that you would have wrote in the native languages.
If the file renders JSX, you will be safe to just copy it over and hook it back up.
To state it another way, go into the folder that has node_modules in it. You shouldn't copy anything that is in that folder except additional files that you created. This is where people normally create an src folder and place all their JavaScript. You probably have an index file in there that points to ./src/app.js or you may have an index.ios.js and index.android.js that both point to a ./src/app.js. Anything inside src is safe.
That's my best answer without seeing your folders and files.
If you intend to copy code from one react native project to another, make sure the code you intend to copy is JS and not any native files. Make sure you do register the correct component using AppRegistry. Rest assured you can copy the code from one project to another.
Assuming you have a project at folder
/my-project/android
/my-project/ios
/my-project/src
Copy my-project and paste it at your desired folder like
/new-my-project
Change git origin
git remote set-url origin https://gitlab.com/..../**.git
Open /new-my-project/android in Android Studio, and then rename app/java/com.myproject to com.newmyproject
Go to app/build.grade and change com.myproject to com.newmyproject and sync
Create firebase project and download google-services.json file and add to new-my-project/android/app
Build application, then test application under metro bundler
npx react-native start
Create keystore, test notifications, change base_url_api, test apk etc Android finish now, iOS
Update pods on new-my-project/ios
pod install && pod update
open myproject.xcworkspace
Change bundle identifier to org.reactjs.native.newmyproject, version to 1.0, build to 1 and desired Display name. Let it index completely
Setup in firbase and replace GoogleService-Info.Plist file and Clean build folder in xcode
Go to developer.apple.com and create identifiers, APNS certificates, profiles
Download certificates from keychain and upload to firebase
Build the project in simulator/device and test it.
Done
Trying to add airbnb/react-native-maps to my react native project and follow the guide at https://github.com/airbnb/react-native-maps/blob/master/docs/installation.md. Option 1,
Option 1: Cocoapods - Same as the included AirMapsExplorer example
Setup your Podfile like the included example/ios/Podfile then run pod install. (If you do not need GoogleMaps support for iOS, then you can probably completely skip this step.)
Open your project in xCode workspace
Drag the following folder into your project:
node_modules/react-native-maps/ios/AirMaps/
If you need GoogleMaps support also drag this folder into your project:
node_modules/react-native-maps/ios/AirGoogleMaps/
After done, I cannot run the project in Xcode, it gives the error, 'RCTImageLoader.h' file not found.
I hv tried run rnpm link and it cannot go through,
rnpm-link info Android module react-native-maps is already linked
rnpm-link info Linking react-native-maps ios dependency
rnpm-link ERR! It seems something went wrong while linking. Error: ENOENT: no such file or directory, open '/Users/nedved/Desktop/NativeCreditcard_office/node_modules/react-native-maps/ios/AirGoogleMaps.xcodeproj/project.pbxproj'
Please file an issue here: https://github.com/rnpm/rnpm/issues
I can find the file /Users/XXXX/node_modules/react-native-maps/ios/AirGoogleMaps.xcodeproj locally, but when clicking, "Project /Users/XXXX/node_modules/react-native-maps/ios/AirGoogleMaps.xcodeproj cannot be opened because it is missing its project.pbxproj file."
Any idea?
