[SOLVED with v2.1.1] Undefined symbols for architecture x86_6: _OBJC_CLASS_$_RNFirebaseDatabaseReference

[D1no]

When compiling our project with RN-Firebase 2.0.5 I get a weird compilation error in xcode:

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_RNFirebaseDatabaseReference", referenced from:
      objc-class-ref in libRNFirebase.a(RNFirebaseDatabase.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I manually added react-native-firebase when it was at 2.0.0. We run the project via pods. Did something in the set-up change since than? I hate those kind of errors.....

platform :ios, '9.0'

target 'name' do

Environment

1. Target Platform (e.g. iOS, Android): iOS
2. Development Operating System (e.g. macOS Sierra, Windows 10): MacOS Sierra
3. Build tools (Xcode or Android Studio version, iOS or Android SDK version, if relevant): xCode Stable
4. React Native version (e.g. 0.45.1): 0.46.3
5. RNFirebase Version (e.g. 2.0.2): 2.0.5

Okay... if anybody comes accross this magic error, try this. It solved the problem (for now).

Close Xcode and packanger.

Clear Xcode Cache rm -rf ~/Library/Developer/Xcode/DerivedData

Go into ios folder cd ios

Clear CocoaPods Cache pod deintegrate && pod cache clean --all

Re-Install Pods pod install

The install can take now a veeery long time - if it seems to be stuck, you should re-setup cocoa with an update before installing again, as follows: gem install cocoapods (you maybe have to use sudo) than pod repo remove master --verbose && pod setup --verbose && pod install --verbose

than pod install

same problem here, it can work when building with react-native run-ios, but it fails when archiving

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_RNFirebaseDatabaseReference", referenced from:
      objc-class-ref in libRNFirebase.a(RNFirebaseDatabase.o)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

[mindhivefi]

I ran into a same issue. For the issue was fixed by upgrading to the latest cocoapods version and recreating the ios project.

[Shinichi52]

i had same issue with RN 0.47.0 xcode: i built success. after i built with command line (react-native run-ios). it's not work with error message

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_RNFirebaseDatabaseReference", referenced from:
      objc-class-ref in libRNFirebase.a(RNFirebaseDatabase.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

update: after i had run react-native unlink react-native-firebase. i tried re-build with command line. it alerted successful but it's crash when startup :(

react-native log-ios: Service exited due to Abort trap: 6

[Damnum]

Same here, the suggestions mentioned above don't help either.

[chrisbianca]

@Damnum @Shinichi52 @mindhivefi @alfonsodev @D1no I've just released v2.1.1 to hopefully fix the problem. Can you see if this fixes it for you?

[Shinichi52]

Hi @chrisbianca, I tried upgrade v2.1.1 and re-install pod. When I ran app with command react-native run-ios. It's crash when startup. Run with xcode is working fine log with react-native log-ios

[Damnum]

For me, this resolved the issue! Thanks @chrisbianca

For the record, for react-native run-ios to work I had to clean my Xcode Cache with

rm -rf ~/Library/Developer/Xcode/DerivedData

and delete the entire local build folder with

rm -rf ./ios/build

[Ehesp]

@Shinichi52 run-ios is not great as it seems to not show you the full errors or warnings. It also has no control over cache cleaning like XCode does. I'd stick with using XCode anyway, as you can't change any of the project settings required to deliver the app without it anyway!

[D1no]

Upgraded from 2.0.5 -> 2.1.1 works

What I did.

Clean the Repo to get rid of all the chaches (stage your changes first): git clean -fdx -e .vscode (exclude folders such as .vscode with the -e flag) Delete xCode Derived Data cache: rm -rf ~/Library/Developer/Xcode/DerivedData Update to 2.1.1: yarn upgrade-interactive (select react-native-firebase and hit enter) Install pods: cd ios && pod install && cd ..

Since we have different schemas, I run the app from xcode.

[D1no]

Thank you guys for the very quick turnaround. Impressive! FYI: We just joined as patrons (https://www.patreon.com/invertase/posts) to support you guys and the react-native-firebase project. Thanks! 🚀

[Ehesp]

Awesome :) Thanks for helping debug it too!

[Aung-Myint-Thein]

I have tried all the methods above and still I get the same error. However, I used manual installation method and followed @AndreiCalazans here and @loukandr .. here but after that I still get above error and it says "undefined symbols for architecture x86_64 react native" :( Anyone any suggestions?

Actually, I tried with pod method but it breaks all the other libraries :(

I am using the following:

"react-native": "^0.55.4", "react-native-firebase": "^4.3.7", Firebase iOS SDK - 5.3.0

I am only using DynamicLink and Messaging. Following is the trace:

[Aung-Myint-Thein]

I set up using pod and it is working fine. So, maybe above comment is not valid anymore. Thanks guys! Followings are the steps I did in my project:

react-native unlink react-native-firebase react-native install --save react-native-firebase cd ios pod init pod update pod install (will get some warnings but the above link shows how to solve them. open xcworkspace file in xcode and solve them.) react-native link react-native-firebase open xcworkspace file in xcode. Build

[vongohren]

@Aung-Myint-Thein did it work with all other linked libraries from earlier? Or what happens to them?

[krisnailafat]

i have the same problem, but im not using cocoapods, is there any way without cocoapods ?

[Aung-Myint-Thein]

I tried without cocoapods way and it was much more complicated and I didnt get it. So, currently, my project is using cocoapods. It is much simpler and not much trouble.

On React-native 60.4, followed everything here. Cannot build the project. (So typical of RN..)

Also ran into this updating to 60.4, unsuppressed by previous solutions. @ollydixon did you find a fix?

[Aung-Myint-Thein]

I got this error again after updating to RN 0.60.4 last night. However, I fixed with all the steps I did as follows:

1. I checked my rnfirebase version and it is not supported for RN 60.4. Most likely it is the case for you guys. So, I had to update it by just changing the version to 5.5.6 then npm i again.

2. Then, I also need to update Podfile to use the latest libraries. I just follow https://rnfirebase.io/docs/v5.x.x/releases/v5.5.x#Upgrade-instructions and tried to run again.

3. Then, it might not run successfully. Then

1) Do product > clean 2) Close Xcode 3) Re-run pod install (from the command line) 4) Re-open the .xcworkspace 5) Do product > clean 6) Try a build

(as mentioned in https://rnfirebase.io/docs/v5.x.x/troubleshooting/ios#Duplicate-Symbols-/-Undefined-Symbols-(build-time-error) )

Another note you guys have to be careful is that RN 0.60.x uses auto-linking and it can give a bit of problem if you don't "unlink" first before updating.

I also wrote a post with my updated Podfile content here. Hope some of them will be useful. Let me know how it goes. The process is really painful but once it is running, the RN 0.60.4 is quite good.

[QuintonC]

I tried following the comment above to resolve my issue, but I continue to receive the error outlined in the first comment.

Undefined symbols for architecture x86_64:

The weirdest thing is that this is on a project that previously built (and is live on the app store). When I stash all of my changes and pull the repo from master to rebuild, the project fails with this error again.

I've followed the guide and updated everything, but to no avail. This is on an ExpoKit project as well.

[mikehardy]

@prasannavenkatesh-colan 👋

1- this issue was closed nearly 2 years ago, it is unlikely anything will apply still 2- react-native 0.58 is nearly 2 years old though! it is unlikely it will work at all now 3- we are on v14.y.y here, the versions you have are unlikely to work anywhere now

I suggest you update to current stable versions and retry. If I had a react-native project based on version 0.58 I would probably pull the javascript aside and just re-init the underlying project

Here's a demo showing a clean integration from start to finish from react-native init, as a guide: https://github.com/mikehardy/rnfbdemo/blob/main/make-demo.sh

[mikehardy]

I prefer npx react-native-clean-project these days, it is a maintained set of all the magic cleaning / reinstall steps

@prasanna-col hi, I am facing the same issue, do you found anyway to fix it?
