Xcode – react-native-svg undefined symbols dylib when compiling on iOS

I’m trying to compile a React Native app on iOS.

Many times I encounter an error related to the linker, which essentially says that dylib reports there are undefined symbols, which are related to some pod modules linked to the project.

In my case I’m having trouble with react-native-svg

To install the package and compile:

$ npm install --save react-native-svg
$ npx pod-install  # or cd ios && pod install && cd ..
$ npx react-native link react-native-svg
$ open ios/<project-name>.xcworkspace &
$ # then compile the react-native project in iOS

So:

  • Package is installed
  • Podfiles are installed
  • Package is linked

Sometimes this happens when compiling for simulator (x86_64) and sometimes it happens when compiling for my device (arm64). It appears randomly, but nothing I do solves the problem. Sometimes it works after a reboot, sometimes not. Sometimes it works after cleaning the build folder , sometimes not. Sometimes it works after restarting Xcode, sometimes not. Sometimes it works after re-running pod install and re-linking works, sometimes not. Nothing appears to work consistently.

Any insight would be appreciated.

The errors are as follows

    It seems like the solution was to go to my Pods and to upgrade the Deployment Target version.

    I was with the exact same error here after added use_frameworks! in my Podfile, I suggest you reinstall to the newest version of this package, only this resolved for me.

    execute this commands if you are using RN >= 0.60:

    $ yarn remove react-native-svg

$ react-native unlink react-native-svg

$ yarn add react-native-svg

$ cd ios && pod install
