I encountered the same issue. Are you guys using obj-C/C++ ?

I was hoping this was the issue for me. On the mainpage of this GIT there is a warning that I should start writing some wrappers around FB code.

⚠️ Be Advised ⚠️

We have begun rewriting the iOS SDK in Swift in order to modernize the code base.Please monitor the changelog for updates to existing interfaces but keep in mind that some interfaces will be unstable during this process. As such, updating to a minor version may introduce compilation issues related to language interoperability. Using symbols now defined in Swift may require using @import syntax from Objective-C and using C++ will likely require workarounds like creating wrappers in Objective-C.Please bear with us as we work towards providing an improved experience for integrating with the Facebook platform.

Will that be the reason on old cores?

As I got 2 Macs, the one with M1 Pro core works fine, but the other with old core encounter the same error.

Try Installing with SPM

what's SPM?

Swift Package Manager

[djMax]

Interesting. I'm in a react-native env, via react-native-fbsdk-next, so I don't think that's an option, but it certainly sounds like a plausible explanation as to why it's breaking.

pod 'FBSDKCoreKit', '14.1.0' works target: iOS 13 xcode: 14.1

[kidc2458]

I found that the content of ios/pods/Target Support Files/Pods-{project name}/Pods-{project name}-framework.sh which was created after running 'pod install' was wrong. I have two mac os that build the same project, and both mac os have the same environment. (maybe) xcode 14.1 mac os 13.0 node 18.12.0 ruby 2.6.10 ... Other than that, the project settings are all the same.

In the build of Mac OS that has the same problem as this issue, the 'install_framework' entry in 'Pods-{project name}-framework.sh' contains the path of FBSDKCorekit.framework It hasn't been done.

All project settings on both Mac OS are the same. Since I use SVN, I have removed all unnecessary files in the project with svn revert, svn cleanup, etc.

But the result of 'pod install' is different.

I'm looking for something that affects 'pod install' among other environment settings.

Please let me know if anything comes to mind.

+

The Mac OS where the issue occurs is Old Mac. (Mac mini 2018 3.2 GHz 6 Core intel core i7) The Mac that produced the correct build is a slightly newer Mac. (MacBook Pro 2019 2.4GHz 8 Core Intel Core i9)

[kidc2458]

I haven't been able to find the exact cause of this issue in the end. I set up all the environments to build the project from scratch, and in the end I was able to get the right result.

I installed and built the same project on a total of 4 Mac with different specs and it worked on the Mac I mentioned before.

I uninstalled brew, node, cocoapods, ruby, xcode, yarn respectively and reinstalled it.

[yhoseph]

I fixed this issue by running this command "pod install --repo-update"

[zeucxb]

I just add FBSDKCoreKit and FBSDKCoreKit_Basics and it works 🙌🏼

[sajibsaha4647]

dyld[24623]: Library not loaded: @rpath/FBSDKGamingServicesKit.framework/FBSDKGamingServicesKit .

still i have problem with this . nothing works for me .

I just add FBSDKCoreKit and FBSDKCoreKit_Basics and it works 🙌🏼

in this way dyld[24623]: Library not loaded: @rpath/FBSDKGamingServicesKit.framework/FBSDKGamingServicesKit same i added and it works for me .

[triplef]

I found that the content of ios/pods/Target Support Files/Pods-{project name}/Pods-{project name}-framework.sh which was created after running 'pod install' was wrong.

I also believe that’s the cause: for some reason the script is missing the install_framework call after updating from v14.1.0 to 15.0.0 or 15.1.0:

@joesus any idea what might be going on here?

My Podfile looks like this:

source 'https://cdn.cocoapods.org/'
use_frameworks! :linkage => :static

target 'MyApp' do
  platform :ios, '12.2'
  pod 'FBSDKCoreKit'
end

[bgoncharuck]

[bastien-shopopop]

Updating cocoapods from 1.11.2 to 1.11.3 fix the issue for me.

[bgoncharuck]

For Flutter users of flutter_facebook_auth. Temporary fix:

In pubspec.yaml

  flutter_facebook_auth:
    git:
      url: https://github.com/darwin-morocho/flutter-facebook-auth.git
      ref: 1ba68fa7357075740591b31a511bb9ba67c8740c # pragma: allowlist secret
      path: facebook_auth

I had 3 macs with XCode 14.1 - all would build / install ipa, 2 of the builds would produce the FBSDKCoreKit error. Running xcode-select --install fixed those 2.

@dragouf I use facebook_app_events too! And also 'flutter_login_facebook' library I have fix it by add just FBSDKCoreKit.xcframework hope that will help u In other Mac,the 'facebook_app_events' library works just fine without doing anything. But in my Mac,I have to add FBSDKCoreKit.xcframework that's weird,same Mac OS version,same XCode version,same Intel Core. nothing is different! If u find something,Please let me Know

[felipe-xavier]

In your Xcode ,go the General tab of your Main Project.. there you will find an Embedded Binaries field and add the required framework there . Crash will be resolved.

This and downgrading are just workarounds, my team has M1 and intel machines which get conflicts when including the SDK manually solution and we'd rather not downgrade the SDK.

M1 machines work fine with SDK 15, but when we add the SDK manually to make intel machines work, it just breaks the M1 machines later due to duplicate entries.

Please, update the SDK with a proper fix.

[greymag]

@joesus is anyone working on a fix for this? This happens on Intel mac and this is pretty huge problem with current SDK version.
