"react": "16.13.1",
"react-native": "0.63.0",
Encountered the below main.jsbundle does not exist. This must be a bug with issue when trying to archive after upgrading to react-native 0.63. was wondering if anyone encounters the same issue
This worked for me in a project involving babel-plugin-module-resolver:
Open your ios/*.xcworkspace in Xcode.
Click on the name of your project in the project navigator.
Click on the name of your target in the pane on the left.
Click on Build Phases.
Expand the Bundle React Native code and images phase.
On the first line of the script, add cd $PROJECT_DIR/.. to go up a directory.
The whole script should look like this:
cd $PROJECT_DIR/..
export NODE_BINARY=node
./node_modules/react-native/scripts/react-native-xcode.sh
Note that this might break if the source of this is a bug in 0.63.0, so you may need to undo this on a future release.
Props to #typester for bringing this up on facebook/react-native #29351.
Found a solution
In Xcode Build Phases -> Copy Bundle Resources, add main.jsbundle
In package.json, add
"scripts": {
"bundle:ios": "react-native bundle --entry-file index.ios.js --platform ios --dev false --bundle-output ios/main.jsbundle --assets-dest ios",
"postinstall": "yarn run bundle:ios"
...
},
so the main.jsbundle will be generated
For me the error occurred because I had imports like this:
import Component from '..';
Replacing those with relative paths (#components/path/to/component) fixed the issue.
Not sure why resolving these paths is problematic now.
I dug into the node_modules/react-native/node_modules/#react-native-community/cli/build/commands/bundle/buildBundle.js and placed a catch block in the buildBundle function in order to see the component(s) with the problematic import.
I think #changey's solution also works, it only requires adding an additional build step in the CI.
Change your babel.config.js to .babelrc.js and it will work
None of the above fixed it for me, but it works with this PR, it'll probably be released soon https://github.com/facebook/react-native/pull/29477
Just in case somebody finds it useful :)
I upgraded from 0.62.5 to 0.63 and encountered the same error.
In my case, I found out the react-native-xcode.sh script executed in the "Bundle React Native code and images" build phase passed the wrong entry file (index.js) to the build command when it should have used index.ios.js. Not sure exactly why this changed in 0.63.
A solution that worked for me was specifying the correct entry file when running the script:
In Xcode, go to Build Phases -> Bundle React Native code and images
Change this part of the script
../node_modules/react-native/scripts/react-native-xcode.sh to ENTRY_FILE=index.ios.js ../node_modules/react-native/scripts/react-native-xcode.sh
Seen similar issue with RN v0.63. Looking at the error logs noticed that the was an issue with Node memory out of range (EG failed to build bundle). I fixed this by adding:
export NODE_OPTIONS=--max_old_space_size=1024
to Bundle React Native code and images phase script
EG:
export NODE_BINARY=node
export NODE_OPTIONS=--max_old_space_size=1024
../node_modules/react-native/scripts/react-native-xcode.sh
if you use M1'series Mac, you can try below.
select Xcode Build Phases tab
expand the Bundle React Native code and images phase
change script like below
cd $PROJECT_DIR/..
export NODE_BINARY=/opt/homebrew/bin/node
./node_modules/react-native/scripts/react-native-xcode.sh
If you have a non-standard Node.js installation, select your project in Xcode, find 'Build Phases' - 'Bundle React Native code and images' and change NODE_BINARY to an absolute path to your node executable. You can find it by invoking 'which node' in the terminal.
As I ran yarn bundle-ios, the following message showed up.
Unable to resolve module config/dimension from src/scenes/Home/index.js: config/dimension could not be found within the project.
I've been using react-native-module-resolver。 I configed "#configs" for path alias。 As you can see above the # is missing。
Corrected it, main.jsbundle was created, finally。
This is a known issue (https://github.com/facebook/react-native/commit/83777cb4fb5dda89c430b7eff9cd1f28d2577831), and is fixed in 0.63.3 https://github.com/react-native-community/releases/blob/master/CHANGELOG.md#v0633
Just update to ^0.63.3 and you'll be good.
For me, I had .babelrc and babel.config.js files in the same project. So RN could not find certain imported libraries. So l modified my .babelrc this way:
{
"extends": "./babel.config.js",
"plugins": [ //bla bla
],
}
this was how the error stopped for me.
This error is specific to the architecture settings of the Xcode project itself. When the wrong arch is set, you'll receive this error because the bundle failed to build.
Here is an updated answer for anyone receiving this error on Xcode 12.5+
Remove Cache, Reinstall Libraries, and Update Pods
Sometimes this error is purely due to cache referencing a different architecture. Use the react-native-clean-project utility to reset all cache related to the project, reinstall packages, and updates pods. This usually clears up the majority of my missing bundle errors.
Verify Xcode Build Settings (Xcode 12.5+ on x86_64)
For Production: you only need to make sure the Architectures settings set to Standard Architectures (default ${ARCHS_STANDARD}). Excluded Architectures should be empty, and if VALID_ARCHS exists, be sure to rename it, then click Archive.
Simulator: You still need to add the VALID_ARCHS variable for the simulator, but set it to the project's workspace, setting the value to x86_64. In order to keep it a single setting for the entire project, make sure VALID_ARCHS isn't already set in Pods project or the App project. If it is, remove the variable, and then set the value on the workspace. Click Run to start your simulation build.
Now when you need to build for production, simply rename VALID_ARCHS to SIM_VALID_ARCHS, and then Archive. 🎉
For those using expo eas build, I was having this same error after upgrading react-native and expo SDK. I fix it using changey solution by adding following to a script called by the hook eas-build-post-install:
if [[ "$EAS_BUILD_PLATFORM" == "ios" ]]; then
echo "Creating main.jsbundle required during build process"
react-native bundle --entry-file='index.js' --bundle-output='./ios/YOURPROJECTNAME/main.jsbundle' --dev=false --platform='ios' --assets-dest='./ios'
fi
I've build a react-native application and suddenly I get this error message on my terminal during run of the command react-native run-ios.
The same code work fine 10 minutes ago and suddenly I get this error message.
Please help...
If you don't have cocoa pods installed you need to sudo gem install cocoapods
run cd ios
run pod install
cd ..
delete build folder
run react-native run-ios
if the error persists,
delete build folder again
open the /ios folder in x-code
navigate File -> Project Settings -> Build System -> change (Shared workspace settings and Per-User workspace settings): Build System -> Legacy Build System`
You should be good to go.
delete the build/ folder in ios/ and rerun
if that doesn't do any change then
File -> Project Settings (or WorkSpace Settings) -> Build System -> Legacy Build System
Rerun and voilà!
In case this doesn't work, don't be sad, there is another solution to deeply clean project
Delete ios/ and android/ folders.
Run react-native eject [Edit: deprecated, so skip this step]
Run react-native link
react-native run-ios
This will bring a whole new resurrection for your project
SOLVED: Always be sure to update your Xcode folks!
Protip: And don't do it from the apple store (but always do it from an official apple website of course)
tip from: http://ericasadun.com/2016/03/22/xcode-upgrades-lessons-learned/
official apple download page: https://developer.apple.com/download/more/
For those who are unable to resolve with above method
Go to project settings in Xcode. Menu File->Project Settings
Go to per-User Project Settings section.
Click on advanced.
Select Xcode Default option. previously this used to be Legacy for my project.
I have analysed on similar lines and concluded that clean is causing the archive to fail. So, the new build system is not clearing the custom/legacy build directory.
delete the build/ folder in ios/ and rerun if that doesn't do any change then
File -> Project Settings (or WorkSpace Settings) -> Build System -> Legacy Build System
Rerun and voilà!
If it still Fails you need to clean full project
Do the following:
Delete ios dir manually
Clean cache Run npm cache clean --force
Run react-native eject
Re-install all packages npm install
Run the link command react-native link
Finally run react-native run-ios
cd ios && rm Podfile.lock && pod install worked for me.
And perhaps few updates if the first didn't help as much, as:
sudo gem install cocoapods
rm Podfile.lock && pod install --repo-update
For me it caused by installing react-native-vector-icons and linking by running the react-native link react-native-vector-icons command.
I just unlinked the react-native-vector-icons by following commands
react-native unlink react-native-vector-icons
cd ios
pod install
cd ..
react-native run-ios
As I already installed an other icon library.
After upgrading react-native, you may have stale dependencies. The steps below should fix it.
cd ios
delete Podfile.lock
pod deintegrate && pod install
Navigate back to package.json directory
run react-native run-ios
In Xcode you can build your project again too
I did this after upgrading to react-native 0.61
Should always start with the simplest first, after wasting hours and days on this error.
And after an extensive amount of research,
Simply
RESTART YOUR MACHINE
This resolved this error.
I'm on
react-native-cli: 2.0.1
react-native: 0.63.3
If you don't have cocoa pods installed you need to:
sudo gem install cocoapods
Then run:
cd /ios
pod install
delete the build folder in ios folder of your react native project
run:
react-native run-ios
if error persists:
delete build folder again
open the /ios folder in Xcode
navigate File -> Project Settings -> Build System -> change (Shared
workspace settings and Per-User workspace settings): Build System -> Legacy Build System
This problem may occur after installing react-native-vector-icons
Open the project in Xcode.
Go to build phases.
go to Copy Build resources.
Remove all .ttf files from here.
Run the application.
I had the same error, but it was caused by the package manager process port being already used (port 8081).
To fix, I just ran the react-native by specifying a different port, see below.
react-native run-ios --port 8090
A popular reason to builds failing and error code 65 is a missmatch between cached pod files and current packages used. Here is how to remove the cache and recreate the pods.
1. Delete Derivate Data - Remove data that includes cached info of the project Example how to do it: https://www.youtube.com/watch?v=f8bTvx0Aoyo
2. Delete .xcworkspace file from ios folder - This is the Xcode project file that gets created when you run pod install we want to recreate it in step 4. This project file uses pods and has a white coloured icon instead of the blue coloured base project without pods.
3. Delete Podfile.lock - Remove old dependencies info so we can recreate them in the next step.
Do a pod-install in ios folder or npx pod-install in root with (React native) - Here we download the pod dependencies again and the pod files only the ones that are used from the current packages are downloaded. A .xcworkspace is regenerated
In my case, the issue was with my Xcode build scheme. When you run react-native run-ios you may see something like,
info Found Xcode workspace "myproject.xcworkspace"*
info Building (using "xcodebuild -workspace myproject.xcworkspace -configuration Debug -scheme myproject -destination id=xxxxxxxx-xxxxx-xxxxx-xxxx-xxxxxxxxx -derivedDataPath build/myproject")*
In this case, there should be a scheme named myproject in your ios configurations. The way I fixed it is,
Double clicked on myproject.xcworkspace in ios directory (to open workspace with Xcode)
Navigate into Product > Scheme > Manage Schemes...
Created a Scheme appropriately with name myproject (this name is case-sensitive)
Ran react-native run-ios in project directory
In case you are using a Mac M1 architecture it is not directly compatible with Cocoapods. If you encounter issues when installing pods, you can solve it by running:
sudo arch -x86_64 gem install ffi
arch -x86_64 pod install
These commands install the ffi package, to load dynamically-linked libraries and let you run the pod install properly, and runs pod install with the proper architecture.
Source: https://reactnative.dev/docs/environment-setup see "Note for Mac M1 users"
run pod install inside ios folder then go back to root folder and run npx react-native run-ios
What worked for me was to rename the project by removing the special characters.
Example: "project_marketplace" to "projectmarketplace"
In this case, I redid the project with react-native init and copied the src and package.json folder.
If you encountered issues with M1.
Try installing the ffi package and running install again.
sudo arch -x86_64 gem install ffi
cd ios
arch -x86_64 pod install
Another solution that I found here works great, basically installing cacoapods with brew (and passing -arm64).
sudo gem uninstall cocoapods
arch -arm64 brew install cocoapods
cd ios
pod install
This could also be due to having custom named schemes, in that case:
cd ios
xcodebuild -list
Find your's, it might have a -dev suffix. Then:
cd .. (root of the app)
npx react-native run-ios --scheme custom-scheme-name
In my case everything solved after re-cloning the repo and launching it again.
Setup:
Xcode 12.4
Mac M1
In my case, none of the answers resolved it, since am not able to open .xcworkspace at all. But the legacy comment hinted to a RN to Xcode <> compatibility issue, so i tried all the previous RN Versions and all below RN#0.64 seem to work with xcode 11.3.1
npx react-native init projectName --version 0.62.0
Thanks
Below work for me though I encounter error code 65 due to I rename an existing project name to a new name which I did for all the files within the project.
My solution was :-
At ios folder level open xworkspace with xcode.
Click on file tab then click on workspace settings.
I clicked on advance then I select xcode default then I clicked on close button.
I clicked on scheme tab which is beside the stop button at the right then I clicked on edit scheme.
When the edit scheme opened I clicked on build tab then I click on manage scheme button.
I selected scheme of my project name then I clicked the minus(-) button to delete it then I clicked on close
I clicked on clean build folder then when its complete I clicked on build tab to rebuild the project.
I clicked on play button which i selected the simulator I want then everything work perfectly again.
I too had an issue with react-native-vector-icons causing this. I still wanted to use the icons though, and I was using VSCode
Workaround was to more or less the same as the manual instructions from the docs but a little different.
npm install --save react-native-vector-icons
copy the .tff files you want to use in node_modules -> react-native-vector-icons -> fonts
create a new folder "fonts" in src -> ios
...paste the .tff files in there
open 'info.plist' in src -> ios -> mobile
on the line above </dict> paste:
<array>
<string>AntDesign.ttf</string>
<string>Entypo.ttf</string>
<string>EvilIcons.ttf</string>
<string>Feather.ttf</string>
<string>FontAwesome.ttf</string>
<string>FontAwesome5_Brands.ttf</string>
<string>FontAwesome5_Regular.ttf</string>
<string>FontAwesome5_Solid.ttf</string>
<string>Foundation.ttf</string>
<string>Ionicons.ttf</string>
<string>MaterialIcons.ttf</string>
<string>MaterialCommunityIcons.ttf</string>
<string>SimpleLineIcons.ttf</string>
<string>Octicons.ttf</string>
<string>Zocial.ttf</string>
<string>Fontisto.ttf</string>
</array>
...or whatever fonts you selected.
I ran react-native run-ios and it worked like a charm.
Some changes in Podfile haven't been updated. Maybe one of your native dependencies has changed.
expo prebuild --clean
cd ios
pod install
yarn ios
In a React Native app, I removed some font assets that I previously linked. For some reason, they didn't get deleted from the Xcode project. I deleted them manually and then it worked.
For our project, we had to run the npx react-native link command in order to get the react native vector icons to show up on Android phones. But that added code to the ios/yourprojectname.xcodeproj/project.pbxproj file.
And that caused the build to fail, throwing an error code 65 and listing out all the fonts that were duplicated.
So, to fix the error, we just removed all of the new code that was added by the npx react-native link command.
If you've built/run your app previous from Xcode and want to go back to using the terminal you need to clean your build folder.
Go to product -> Clean Build Folder
In my case it was an issue between different installations of npm installed via nvm and homebrew which somehow messed up my setup.
Building via Xcode usually works without solving the initial problem. I have solved it as follows. Notice, that this guide is suitable if you want to use nvm.
First, we remove a possible installation of npm and yarn using brew as follows.
brew uninstall npm
brew uninstall yarn
We might want to remove nvm as well.
rm -rf "$NVM_DIR"
Next, we reinstall nvm by executing the following command.
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | <ShellOfYourCoice>
Replace <ShellOfYourCoice> with bash if you are using bash, with zsh if you are using zsh.
Add the following content to ~/.bash_profile (.bashrc) for bash or to ~/.zshrc for zsh (you might need to create these files).
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
For zsh, we might need to fix some permissions. Execute the following command.
compaudit | xargs chmod g-w
Then, source the shell of your choice. Verify the installation by executing the following.
nvm --version
which npm
The last command should print something similar to the following.
/Users/<userName>/.nvm/versions/node/v16.10.0/bin/npm
If yarn were installed using npm previously, we first remove it.
npm uninstall yarn
Next, we reinstall it.
npm i -g yarn
These steps fixed the issue for me.
For macOS, make sure that none of the names of the directories has a space character ' ' in their names. I spent hours figuring out the problem and the problem was so small.
error Failed to build iOS project. We ran "xcodebuild" command but it exited with error code 65
That was my error and i resolve this error with the following commands:-
1- Uninstall Ruby with: brew uninstall ruby --force
2-Uninstall CocoaPods. At first, try to list all CocoaPods versions / components with gem list --local | grep cocoapods. Then uninstall them one by one, in my case:
1- sudo gem uninstall cocoapods
2- sudo gem uninstall cocoapods-core
3- sudo gem uninstall cocoapods-downloader
,cocoapods-plugins
,cocoapods-search
,cocoapods-trunk
,cocoapods-try
etc.
3- As a next step I was able to reinstall ffi and then CocoaPods with:
i) sudo arch -x86_64 gem install ffi
ii) sudo arch -x86_64 gem install cocoapods
Once done, I could run pod install as expected. Note that I had the Terminal open all the time in standard mode - no Rosetta required.
If you're like me and tried to change the name of the TestApp-folder. Notice the last line in the warning:
xcodebuild: error: The workspace named "TestApp2" does not contain a
scheme named "TestApp-tvOS". The "-list" option can be used to find
the names of the schemes in the workspace.
Not changing the TestApp name in the command nor after from this, helped me get rid of the message and the app was built:
react-native init TestApp --version=react-native#npm:react-native-tvos#latest
there was some issue while creating the app
so in my case i just deleted the package-lock.json and did npm i
after that
cd ios/ and pod install
I am trying to implement react-native-google-sigin package to my react-native Ios project . I have configured everything.
But now the problem if I include google framework to my project there is a pop an error and As soon as I remove it. It works!!
I really don't know why m getting build fail with the following error
Every time i include ios/GoogleSdk frameworks in my project.
I don't know why or how but I ran into this issue and after numerous cleans, DerivedData deletes etc., the solution that worked for me was to follow XCode's advice on upgrading to the recommended settings and changing the iOS Deployment Target of RNGoogleSignIn project to 8.0. I'm using XCode 9 if that helps.
This is how I solved this:
rm -rf node_modules/ ios/
(Copied my podfile to another location)
npm install & react-native upgrade
(this will give me a error free start cause by react-native link)
cp my podfile inside ios/ Pod install
Followed the remaining steps from react-native-google-signin
Added the following to my login.js (iosCLientId and CLientId are different Id's)
await GoogleSignin.configure({
iosClientId: 'iosClientId',
webClientId: 'webClientId',
offlineAccess: false
});
Open Xcode Clear and Build the project.
Note: I would have easily removed the googlesdk(frameworks), links and library . But instead I choose to get get a fresh start. Hope this helps anyone
In X-Code project of react native, getting error
config.h file not found.
Here is version detail :
react-native-cli: 2.0.1
react-native: 0.51.0
How to solve it?
Close Xcode.
Open Terminal, go to your project's root folder and run:
cd node_modules/react-native/third-party/glog-0.3.4/
Run the configure script:
./configure
Open Xcode and try to run your app.
I had the same issue, using this steps solves for me:
Running into the same issue here after upgrading from 0.44. None of the above solutions or clearing caches did the trick for me. Here's what I did to get things working again:
In the Terminal, navigate to the react-native/third-party/glog folder inside node_modules (for me, this was cd node_modules/react-native/third-party/glog-0.3.4)
Once actively in this folder, run sh ../../scripts/ios-configure-glog.sh
Glog is configured and the required config.h header file is created for Xcode to find
Run your iOS BUILD
Regards!
When project files get messed up for me. I typically follow these steps.
rm -rf node_modules
npm install
react-native upgrade (Only changing affected files, so IOS for you)
react-native link
npm start --reset-cache
(In another terminal)
react-native run-ios
These steps worked for me:
rm -rf ~/.rncache
rm -rf node_modules/
npm install
npm start
You need to change to the legacy build system in Xcode 10 and install third party scripts manually.
1:
File -> Project/Workspace settings
Build System: dropdown -> change to Legacy Build system
2: Follow this to manually install third party scripts for RN:
Clean RN cache
$ rm -rf ~/.rncache
Re-install the deps
$ cd your_project_path
$ rm -rf node_modules/ && npm install
Then install the third-party
$ cd node_modules/react-native/scripts
$ ./ios-install-third-party.sh
Run the commands below if glog installation failed.
$ cd ../third-party/glog-0.3.x
$ ./configure
It works for me, I hope it helps for you.
If above all answers don't work,
Please check that there is no space in any directory name of the full path and not only the project directory name.
While in terminal, it accepts throgh My Disk as My\ Disk but xcode do not recognize that.
If its in My Disk directory, try after moving it to Desktop or any other directory which doesn't have space in their name.
configure: error: unsafe absolute working directory name Issue:
-Open Terminal, go to your project's root folder and run:
cd node_modules/react-native/third-party/glog-0.3.5/
Run the configure script:
./configure
got error: configure: error: unsafe absolute working directory name
try to created app in desktop and from there run ./configure command.
Please note with XCOXE 10, and Mojave MAC OS , I had same issue, ./configure was showing some permission issue, I had set permission "777" to project folder enclosing with inner folders
This is the linking issue in xcode. You just need to re-link the files.
Please follow the below steps:
Open you peoject's root directory then open node-module -> react-native -> React.
Open React.xcodeproj file in xcode.
You will see missing (showing red in color) files under the third-party folder
Just run the React.xcodeproj project.
After completion close this project & open you project file.
Delete Drive data & Clean the project & run.
If after running the project you are getting linking issue then please make sure you have added all the (ios) products () come under the Libraries -> React.xcodeproj -> Products in your Build Phases -> Link Binary With Libraries.
If everyone has tried solving the issue by this
Open Terminal, go to your project's root folder and run:
cd node_modules/react-native/third-party/glog-0.3.4/
Run the configure script:
./configure
But still not got the solution then,
Go to your Xcode and check if there any library is missing. Add that library and then perform this above step.
Although the already mentioned answers are correct but still few guys are struggling, as only configuring the glog doesn't sometimes resolve the error.
Here I have written a detailed solution to the problem.
Solution: config.h file not found mutex.h During Archive.
The steps are the following:
Remove node_modules directory
Clear Cache
Install packages again with Yarn
Install third party
Configure Glog
Make & Make install glog
For all these above steps the I have shared commands in the above mentioned article, so not going to write again. I hope it will solve problem for guys who are still struggling.
After days of research on the internet I still haven't solved my problem yet.
I am using react-native-svg and I am having the same issues:
No component found for view with the name "RNSVGPath"
Or this one:
Invariant Violation: Native component for "RNSVGSvgView" does not exist
I tried a lot of things, including:
react-native unlink react-native-svg
npm uninstall react-native-svg
npm install react-native-svg
react-native link react-native-svg
react-native run-ios
Also:
pod 'RNSVG', :path => '../node_modules/react-native-svg'
rm -rf node_modules
npm install
react-native run-ios
But still nothing...
Here's the versions I am using:
"dependencies": {
"react": "16.1.1",
"react-native": "0.50.3",
"react-native-svg": "^6.0.1-rc.1"
}
I tried to build it from XCode directly and still nothing...
Thanks for your help guys !
You should try to do this:
npm install react-native-svg --save //(again)
react-native link react-native-svg //(again)
watchman watch-del-all
rm -rf node_modules/ && yarn cache clean && yarn install
Then in another terminal
npm start -- --reset-cache
Before starting your ios app with react-native run-ios, you have to add libRNSVG.a manually to your Linked Frameworks and Libraries in Xcode
And then ... Tada
SVG Problem, I also stuffed 4 hours and get the solution.
Automatic link:
react-native link react-native-svg
Does not work automatically then you do with manually.
Manual Link:
1 Append the following lines to android/settings.gradle:
include ':react-native-svg'
project(':react-native-svg').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-svg/android')
2 Insert the following lines inside the dependencies block in android/app/build.gradle:
implementation project(':react-native-svg')
3 Open up `android/app/src/main/java/[...]/MainApplication.java
Add import com.horcrux.svg.SvgPackage; to the imports at the top of the file.
Add new SvgPackage() to the list returned by the getPackages() method. Add a comma to the previous item if there's already something there.
I had this problem because "react-native link" is broken as of RN 0.51. Linking manually after complete removal and reinstall fixed it on iOS.
Svg have problem with version
first, unlink svg then remove npm of svg then install new one
"dependencies": {
"react": "16.1.1",
"react-native": "0.44.0",
"react-native-svg": "5.1.8"
}
I had the same issue but on Android.
So, if you are in the same conditions, here is something that fixed it, the trouble happened specifically on MainApplication, so you want to look at :
open android/app/src/java/com/*/MainApplication.java
add import com.horcrux.svg.SvgPackage; on top with other imports
add new SvgPackage() along the others in the list getPackages() (~line 30-ish)
