[Pashkagreen]

🐛 Bug Report

Hello guys. After adding all the staff im trying to launch my application, then it build successfully, and then immediately crashes, because due to stacktrace it cannot find FB libraries. Please help me, I know that the reason is in paths to libs but dont know how to fix it. Attach my code below

To Reproduce

Add everything following the docs
-> build project

Expected Behavior

Successful app launching

Code Example

Error-trace in Xcode:

Actually there are no such files in usr/lib/swift. In which way the FB-libraries should get into this folder?

[mikehardy]

Hey, this is a mess, in your Podfile:

pod 'GoogleSignIn', '> 6.2.2'
pod 'Firebase/Analytics'
pod 'Firebase/Crashlytics'
pod 'Mindbox'
pod 'FBSDKCoreKit'
pod 'FBSDKLoginKit'
pod 'FBSDKShareKit'
pod 'FBSDKGamingServicesKit', '> 15.0.0'
pod 'Firebase', :modular_headers => true
pod 'FirebaseCoreInternal', :modular_headers => true
pod 'GoogleUtilities', :modular_headers => true
pod 'FirebaseCore', :modular_headers => true

1. Do not add the FBSDK Pods directly, autolinking takes care of it (web search "react-native cli autolinking")
2. Do not add the Firebase SDKs directly, autolinking does that if you have react-native-firebase installed
3. and also, as the maintainer of react-native-firebase 👋 do not do that modular_headers stuff as an unsupported workaround to avoid use_frameworks! :linkage => :static in your Podfile, you must include use_frameworks to use current react-native-firebase

No idea what all the mindbox stuff is but your build failure is going to be a local problem in your local project and not our responsibility

We provide what is in effect a minimal example of integration + build, and it works successfully (https://stackoverflow.com/help/minimal-reproducible-example)

It's our example, and it's built by a script even, so you can try it yourself starting with npx react-native init ...: https://github.com/thebergamo/react-native-fbsdk-next/blob/master/refresh-example.sh

Read that script and all the comments in it, they are useful

[HaidarZ]

I've got the same error mentioned above although my Podfile is never touched, and everything is kept as the app was just initialized.
The error appeared when I upgraded the library to version 11.
My react native version is 0.69.6

[Pashkagreen]

I've got the same error mentioned above although my Podfile is never touched, and everything is kept as the app was just initialized. The error appeared when I upgraded the library to version 11. My react native version is 0.69.6

thank man im try to downgrade lib version

[HaidarZ]

Everything is back to normal after I've downgraded back to v10.1.0

[mikehardy]

So our example script here is a minimal reproducible example (https://stackoverflow.com/help/minimal-reproducible-example)

And it works. So the burden of proof that there is an issue is on you, those having the problem.

Please also note that versions of everything are important (your Xcode, your pod version, your macOS and iOS versions where this happens, react-native versions, version of this library etc - https://stackoverflow.com/help/how-to-ask)

No comments here will help move this forward without a minimal reproducible example that shows the problem, wth information needed to run it and reproduce it.

Efficiently triaging issues and finding root causes is real work but it is how to move things forward. If anyone makes the effort, we might be able to pin this down to the exact reason it happens. Until then, the only reproducible example I've got is one that works.

Dont know why, but downgrading to 8.0.0 has helped me. Maybe the problem was in mismatch between differents libs, pods etc. However, big thank to you, @mikehardy , for your advices and your creation!)

facebook/facebook-ios-sdk#2121

[mikehardy]

Oh that looks really subtle - I wonder what we need to do here in order to handle that? 🤔 here are the frameworks they mention:

facebook/facebook-ios-sdk#2121 (comment)

But I thought we brought all of them in our podspec thus they should all be embedded already. I dunno - I still have no problem in a release version personally so I cannot triage. Good link though @EduCarloto

[mikehardy]

This appears to be an upstream issue but it is affecting folks and generating duplicate issues. Going to reopen and pin it

[robsco]

FYI, for anyone else googling...

Adding those FBSDKCoreKit, CoreKit_Basics fixed this for me, but only when including the GamingServices one - to FrameWorks, Libraries and Embedded Content.

from facebook/facebook-ios-sdk#2121 (comment)

This is all with a fresh new build on the latest RN (0.70) - as I'm porting my existing app over, and switching to this lib instead of the original react-native-fbsdk one.

Let me know if/what you want to see from my project.

[KrisLau]

@Pashkagreen @mikehardy Was this closed by mistake? Still seems to be occurring whenever I upgrade to >v11

[mikehardy]

Original poster closed it but it does not seem to be resolved

[KrisLau]

I'm guessing this is not the ideal solution but following this steps:

• dyld[38703]: Library not loaded: @rpath/FBSDKCoreKit.framework/FBSDKCoreKit facebook/facebook-ios-sdk#2121 (comment)

And adding FBSDKGamingServicesKit as well:

Allowed it to build.

[jessiemblack]

@KrisLau I was able to upgrade react-native-fbsdk-next to v 12 by linking those 3 frameworks you mentioned and also changing my platform in my Podfile to:
platform :ios, '12'

[mikehardy]

🤔 so at this point, we have a (kind of terrible looking, if I'm honest, but that is not your fault..) workaround, or otherwise it is perhaps best to stay on a previous version until the upstream SDK has some resolution I suppose. I'm sad this is happening but it still does not really seem to be in the control of this module.

Unless perhaps we could do some Podfile (or, from a module perspective: podspec) magic to get those frameworks linked for people as part of the normal pod install process?

[robsco]

Out of interest, could you explain the issue, just to make all this less of a blackbox/black magic, for simple folk like me.

It'd be nice to understand just a little bit of why this is failing, especially if it may ever happen in the future, to save hours of Googling.

Pods, Podspec, linking, etc. just a quick overview would be great.

[mikehardy]

Sorry, I don't have the time for that. Each of the subjects is the kind of thing that requires actual reading and there's no shortcut to the actual knowledge as far as I know

[jackchengck]

Is that any stable version of react-native-fbsdk-next can be used right now?
i have been burnout to trying to fix this on an urgent project

[KrisLau]

@jackchengck either downgrade to v10 or follow the workaround:

• [IOS] App Crash "dyld" error Library not loaded / upstream issue it seems #324 (comment)

[phantrungviet98]

i am facing the same issue. I am using Hackintosh, maybe it is the issue ? @Pashkagreen

Hi gays. I resolved problem.

I add addToAllTargets="true"

<iosPods>
    <iosPod name="FBSDKCoreKit_Basics" version="~> 15.1" addToAllTargets="true">
        <sources>
            <source>https://github.com/CocoaPods/Specs</source>

    </iosPod>
    <iosPod name="FBSDKCoreKit" version="~> 15.1" addToAllTargets="true" />
    <iosPod name="FBSDKLoginKit" version="~> 15.1" addToAllTargets="true" />
    <iosPod name="FBSDKShareKit" version="~> 15.1" addToAllTargets="true" />
    <iosPod name="FBSDKGamingServicesKit" version="~> 15.1" addToAllTargets="true" />

same error ....

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

[SalaarFiend]

Hello!
I had the same problem, but I solved it and told about it here.
I hope this helps someone!

[robsco]

I may be mistaken but that looks completely unrelated, it's nothing to do with FBSDK.

[SalaarFiend]

I may be mistaken but that looks completely unrelated, it's nothing to do with FBSDK.

Hi, yes it is, there is no FBSDK
But it's more like an example, if you go through the steps in the guide, you can find the root of the problem

[phantrungviet98]

Just updated cocoapods to latest version (1.12.1 now) and pod install again then the issue was gone guys

[robsco]

I confirm that too, I was able to remove the embedding and signing in xcode and it all works fine.

[anieve01]

I too just updated cocoapods to the latest version (1.14.3 now) and then the issue was gone.
I'm using react native expo and I had the error below similar to the OP above and now this issue is resolved.

npx expo prebuild --platform ios --clean
xed ios

Then in xcode run the app on a physical device. It worked.
Thanks @phantrungviet98 and @robsco
