On Xcode before upgrade 11, things work correctly and font assets copy without fatal error.

After Xcode 11 stable released and upgraded, it required fonts removal under [CP] Copy Pods Resources in Build Phases. Subsequent pod update brings them back, needing manual removal again.

Not sure if this is fixable only with special treatment on Xcode >= 11?

[efstathiosntonas]

same here with 0.61.0-rc.3 and xcode 11 11A420a mojave 10.14.6

[chescko29]

Same here.

It looks like a bug or some new issue with new Xcode version.

Error response is:

Failed to build iOS project. We ran "xcodebuild" command but it exited with error code 65.

Detailed response:

That response repeat for each .ttf file used by the library.

I had to temporary react-native unlink react-native-vector-icons, and the project build again, but with not icons.

Find a solution, simply remove duplicate reference fonts in "Copy Bundle Resources" NOT in "[CP] Copy Pods Resources"

[jacklj]

Removing duplicate font files in Copy Bundle Resources worked for me.

The problem seems to be caused by the new autolinking feature in React Native 0.60 - the line use_native_modules! in ios/Podfile means when you do pod install, any pods found in node_modules are automatically linked. This means that links to all font files are added to [CP] Copy Pods Resources when you do pod install.

If you previously installed react-native-vector-icons manually by adding the font files to Copy Bundle Resources, you then get a "Multiple commands produce..." fatal build error.

So to fix the problem, just remove the font files from Copy Bundle Resources, so that they are only in [CP] Copy Pods Resources.

Hi jackli,
I tried it but it created a new problem :(

[KaneNguyen]

@jacklj can you help me, pls !

[awgeorge]

Is there anyway to disable this feature? We're still on .59 and the linking happens in our build process. We don't have our workspace committed, the pipeline literally does a pod install and react native link every time. Now our builds fail as its duplicating these fonts.

[keisnet]

@awgeorge We're in the same situation, what worked for us was to just choose the legacy build system in xcode 11.1.

[webdesign2be]

I had the same issue with the double linking stuff on Xcode.

"react-native": "0.61.5"
"react-native-vector-icons": "^6.6.0"

Xcode: 11.2.1

I used this solution to get it to work for me: #661 (comment)

But on the console i get this:

error: React Native CLI uses autolinking for native dependencies, but the following modules are linked manually:
react-native-vector-icons (to unlink run: "react-native unlink react-native-vector-icons")
This is likely happening when upgrading React Native from below 0.60 to 0.60 or above.
Going forward, you can unlink this dependency via "react-native unlink <dependency>" and it will be included in your app automatically.
If a library isn't compatible with autolinking, disregard this message and notify the library maintainers.
Read more about autolinking: https://github.com/react-native-community/cli/blob/master/docs/autolinking.md

error: Could not find the following native modules: RNVectorIcons. Did you forget to run "pod install" ?

As long as I don't install the pod RNVectorIcons all works as expected.
But that can't be more than a temporary workaround.

[ulises-jimenez]

For anyone else who didn't know this, Copy Bundle Resources can be found under the Build Phases` tab in the target in your project

Thanks. Everyone providing a solution but no one saying where it is 👍

[pacozaa]

@ulises-jimenez the real mvp

[ManigandanRaamanathan]

Fixed it by removing fonts in the Copy Bundle Resource

[leonardomarciano]

Real problem with module.

Fixed it by removing fonts in the Xcode - Build Phases/[CP] Copy Bundle Resource

[njdullea]

Only remove fonts from build phases that are part of RNVI, if you are adding your own fonts you will need these under Copy Bundle Resource.

[jonasgroendahl]

Is there any way to avoid having manually go into XCode and remove the fonts from the Copy Bundle Resource tap when launching a new project using react-native-vector-icons and custom fonts with RN 0.6+ (autolink feature)?

[marktdodds]

@jonasgroendahl This fixed it for me #1074 (comment)

[jonasgroendahl]

@marktdodds thanks, this worked! :)

[lore978]

Be sure to have unchecked the “Target Membership”

[RnbWd]

It'd be nice not to have to manually remove this every time I run pod install.

[MattiasMansson]

@RnbWd Incase you haven't found your workaround yet, my approach to avoid having to remove it after every pod install was the following:

1. yarn add react-native-vector icons
2. Go into node_modules/react-native-vector-icons/Fonts and copy the fonts you wish to use.
3. Place the copied fonts in a folder (in my case src/assets/icons)
4. Include the icons folder in your react-native-config.js

module.exports = {
  assets: ['./src/assets/icons']
};

5. Modify node_modules/react-native-vector-icons/react-native-config.js to the following

module.exports = {
  dependency: {
    assets: [],
  },
};

6. Inside node_modules/react-native-vector-icons/RNVectorIcons.podspec, remove the s.resources = "Fonts/*.ttf" line entirely.

require 'json'
version = JSON.parse(File.read('package.json'))["version"]

Pod::Spec.new do |s|

  s.name           = "RNVectorIcons"
  s.version        = version
  s.summary        = "Customizable Icons for React Native with support for NavBar/TabBar, image source and full styling."
  s.homepage       = "https://github.com/oblador/react-native-vector-icons"
  s.license        = "MIT"
  s.author         = { "Joel Arvidsson" => "joel@oblador.se" }
  s.platforms      = { :ios => "9.0", :tvos => "9.0" }
  s.source         = { :git => "https://github.com/oblador/react-native-vector-icons.git", :tag => "v#{s.version}" }
  s.source_files   = 'RNVectorIconsManager/**/*.{h,m}'
  s.preserve_paths = "**/*.js"
  s.dependency 'React'

end

7. Run npx patch-package react-native-vector-icons.
8. Run cd ios && pod install && cd ..
9. Run npx react-native link
10. Add "postinstall": "npx patch-package" to the scripts in package.json so the patch is automatically applied after every install.

@fungilation, i am pretty sure that this issue is very much still alive. let me know if i am missing something. i just wasted almost 90 minutes trying to figure out why this was happening in my app after upgrading some tooling. it would be unfortunately if this kept happening to more folks.

it seems like the crux of the problem is that the font files are being referred to by both the react-native.config.js and the podspec.

the reference to the font files as assets in the react-native.config.js will cause the react-native link to load the fonts as a resource for the App project.

while the reference to the font files as resources in the RNVectorIcons.podspec will cause pod install to load the fonts as resources for the Podfile project.

i suspect that the solution is to update either react-native.config.js or podspec to that the fonts are not double counted.

[carlost]

so to follow up on my earlier post ... i have a post install hook in my package.json that patches the react-native.config.js file in react-native-vector-icons to remove the assets: ['Fonts'] config. that resolves this issue.

[orinoco]

To build on @carlost strategy, for me it was the podspec. Adding this to the scripts section on package.json fixed it for me.

"postinstall": "sed -i '' '/s.resources/d' ./node_modules/react-native-vector-icons/RNVectorIcons.podspec"

[29er]

@orinoco none should have to do that. Ever.

[lsbyerley]

for me, the safest and easiest way was:

npx react-native unlink react-native-vector-icons
npm uninstall react-native-vector-icons
npx pod-install
npm install react-native-vector-icons
npx pod-install
npx react-native run-ios

that's it!

which method did you use for the ios installation (https://github.com/oblador/react-native-vector-icons#ios) ... the cocoa pods one? I'm still getting a Unrecognized font family Material Design Icons error when running npx react-native run-ios command

[goff-studio]

for me, the safest and easiest way was:
npx react-native unlink react-native-vector-icons
npm uninstall react-native-vector-icons
npx pod-install
npm install react-native-vector-icons
npx pod-install
npx react-native run-ios

that's it!

React Native Link [that I'm working on 0.64 version, so basically, Linked automatically after installation.

[alitele]

For those want to know the reason behind it.

When React has already auto linked vector icons and you do manual link there comes duplicate resources.
Cheers.

[nabilfreeman]

Whyyyyyyyyyy is this still a thing :(((((((((((((((((

[christophermaloney]

I had to uncheck "For Install builds only" on [CP] Copy Pods Resources for it to work for me.
I also manually added the font names into the "Fonts provided by application" section in the info.plist and removed the font files from Copy Bundle Resources but not sure if that was required.

Hopefully this helps someone.

[acro5piano]

1. Follow the official instruction
2. Remove all font files from "Copy Bundle Resources" as described in this thread

My fault was not editing my "info.plist"

[thangpq]

Same here.

You save my life :(
Many thanks

perfect !

[tti-prasad]

For anyone else who didn't know this, Copy Bundle Resources can be found under the Build Phases` tab in the target in your project

Thank you. You saved my day Man!!

[ssathishppm]

Any option to remove those files from copy bundle resources dynamically (using command line) OR how to avoid adding those files

[vjcspy]

for me, the safest and easiest way was:

npx react-native unlink react-native-vector-icons
npm uninstall react-native-vector-icons
npx pod-install
npm install react-native-vector-icons
npx pod-install
npx react-native run-ios

that's it!

It work perfectly!

[Danirill]

Does anyone know how to fix this problem with AppCenter?

[mpeguese]

Following this video finally got my fonts to show up. I was getting red question mark for a few hours and duplicate error message. Hope this helps someone out.

remove all ocurrence of the duplicate tff files

[saravanakumargn]

[Jcs1994]

you all were on xcode while i was looking on vscode xD

[KrisLau]

UPDATE: Not sure what fixed it but it works now

Nothing working for me. Anyone have any ideas? All the fonts added in my Info.plist with no duplicates:
.
Removing them from the Copy Bundle Resources solves the multiple commands produce error but that gives me and Unrecognized font family error:

I also tried @goff-studio's workaround of unlinking, uninstalling and reinstalling the package and @mpeguese's video (creating a Fonts folder in the project folder) with the same results as above,

My app builds fine but its the deploys using Fastlane that are having issues

[Shaxadhere]

removing icon files from Copy Bundle Resources worked for me

[rrsalian16]

removing icon files from Copy Bundle Resources worked for me

this worked for me

[anietieasuquo]

I didn't have to remove the icon files manually.
The easiest solution is to create a file in the root of the project: react-native.config.js, and add the following content;

module.exports = {
  dependencies: {
    'react-native-vector-icons': {
      platforms: {
        ios: null,
      },
    },
  },
};

You might have to rerun yarn install and also install pods again.

[elibroftw]

Would be nice if the following was in the README.md telling users to remove the font files rather than adding them if they are using autolinking (the default on the latest react native).

So to fix the problem, just remove the font files from Copy Bundle Resources, so that they are only in [CP] Copy Pods Resources.

[Dat-Mobile]

For me, I deleted Fonts folder inside project and it works

I listed the fonts in Info.plist

It's 2024, and this is the best answer here. Thanks for sharing!

[atultiwaree]

By Mistake I've deleted copy bundle resources now after build I'm getting black screen how do I fix this ?
