Steps to reproduce

Our game uses unity2019，write podfile as this：

target 'UnityFramework' do

inherit! :search_paths
pod 'FBSDKLoginKit', '13.2.0'

end

#target 'Unity-iPhone' do
#inherit! :search_paths

#pod 'OpenSSL-Universal', '1.1.1100'

#end
�

Code samples & details

pod 'FBSDKLoginKit', '13.2.0'

mayyang · 2022-10-11T10:40:32Z

After pod install，I got the warning like this：

[!] The Podfile contains framework or static library targets (UnityFramework), for which the Podfile does not contain host targets (targets which embed the framework).
If this project is for doing framework development, you can ignore this message. Otherwise, add a target to the Podfile that embeds these frameworks to make this message go away (e.g. a test target).

but I have to use it like the podfile as above。

After updating from FacebookUnitySDK 9.2.0 to 14.0.0 I got the same error.
(Unity 2020.3.32f1)

Managed to fix this by changing Podfile from:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '11.0'

target 'UnityFramework' do
  use_frameworks! :linkage => :static
  pod 'FBSDKCoreKit', '~> 14.0'
  pod 'FBSDKCoreKit_Basics', '~> 14.0'
  pod 'FBSDKGamingServicesKit', '~> 14.0'
  pod 'FBSDKLoginKit', '~> 14.0'
  pod 'FBSDKShareKit', '~> 14.0'
end
target 'Unity-iPhone' do
end
use_frameworks!
use_frameworks!

to:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '11.0'

target 'UnityFramework' do
  use_frameworks! # changed to dynamic linkage
  pod 'FBSDKCoreKit', '~> 14.0'
  pod 'FBSDKCoreKit_Basics', '~> 14.0'
  pod 'FBSDKGamingServicesKit', '~> 14.0'
  pod 'FBSDKLoginKit', '~> 14.0'
  pod 'FBSDKShareKit', '~> 14.0'
end

the same trouble.
anyone help?

Solution from @tatsuki5820iso seems work. I just want to add some more info, instead of manually editing Podfile, you guys can untick Link frameworks statically in iOS Resolver Setting (from EDM menu in Unity) which will do similar for every build

I am facing the same issue now. Have you managed to solve your problem? I am using version 16.1.0, and after adding the relevant xcframework to the "Frameworks, Libraries, and Embedded Content" entry, the test runs normally. However, the app crashes after uploading to TestFlight and opening it.

Hey,
when I remove the "Link frameworks statically" in the "External Dependency Manager".
Strangely, I get a linker error.

Here's a proposed solution to the linker error

I don't understand why linking dynamically would cause a linker error at build time.
Also this is all making my build process messy.
Can anyone explain what is actually going on?

I encountered this problem after integrating the Facebook SDK, which didn't seem to play nicely with the AppLovin MAX SDK settings.

A mixture of the above solutions worked for me. I'll list the details below.

Unity Editor: 2021.3.25f1
AppLovin MAX Plugin (Unity): 5.11.2
AppLovin MAX Plugin (iOS): 11.11.2
Facebook SDK: 16.0.1
Xcode Version: 14.2

First, I changed my iOS Resolver settings to the following:

These settings are different from what AppLovin's integration instructions recommend, but it was the only way I managed to get things working.

My FacebookSDK > Plugins > Editor > Dependencies.xml file looks like this:

<?xml version="1.0" encoding="utf-8"?>
<dependencies>
    <androidPackages>
        <androidPackage spec="com.parse.bolts:bolts-android:1.4.0" />
        <androidPackage spec="com.facebook.android:facebook-core:[16.0,17)" />
        <androidPackage spec="com.facebook.android:facebook-applinks:[16.0,17)" />
        <androidPackage spec="com.facebook.android:facebook-login:[16.0,17)" />
        <androidPackage spec="com.facebook.android:facebook-share:[16.0,17)" />
        <androidPackage spec="com.facebook.android:facebook-gamingservices:[16.0,17)" />
    </androidPackages>
    <iosPods>
        <iosPod name="FBSDKCoreKit_Basics" version="~> 16.0" />
        <iosPod name="FBSDKCoreKit" version="~> 16.0" />
        <iosPod name="FBSDKLoginKit" version="~> 16.0" />
        <iosPod name="FBSDKShareKit" version="~> 16.0" />
        <iosPod name="FBSDKGamingServicesKit" version="~> 16.0" />
    </iosPods>
</dependencies>

After building the project to iOS, it generates a Podfile looking like this:

source 'https://cdn.cocoapods.org/'
platform :ios, '12.0'

target 'UnityFramework' do
  pod 'AppLovinMediationAdColonyAdapter', '4.9.0.0.4'
  pod 'AppLovinMediationByteDanceAdapter', '5.4.0.7.0'
  pod 'AppLovinMediationChartboostAdapter', '9.4.0.0'
  pod 'AppLovinMediationFacebookAdapter', '6.14.0.0'
  pod 'AppLovinMediationGoogleAdapter', '10.9.0.1'
  pod 'AppLovinMediationIronSourceAdapter', '7.4.0.0.1'
  pod 'AppLovinMediationUnityAdsAdapter', '4.8.0.1'
  pod 'AppLovinMediationVungleAdapter', '7.0.1.0'
  pod 'AppLovinSDK', '11.11.2'
  pod 'FBAudienceNetwork', '~> 6.4.1'
  pod 'FBSDKCoreKit', '~> 16.0'
  pod 'FBSDKCoreKit_Basics', '~> 16.0'
  pod 'FBSDKGamingServicesKit', '~> 16.0'
  pod 'FBSDKLoginKit', '~> 16.0'
  pod 'FBSDKShareKit', '~> 16.0'
end
target 'Unity-iPhone' do
end
use_frameworks! :linkage => :static

However, I had to manually remove the pod 'FBAudienceNetwork', '~> 6.4.1' line to make Xcode happy. So my final Podfile looks like this:

source 'https://cdn.cocoapods.org/'
platform :ios, '12.0'

target 'UnityFramework' do
  pod 'AppLovinMediationAdColonyAdapter', '4.9.0.0.4'
  pod 'AppLovinMediationByteDanceAdapter', '5.4.0.7.0'
  pod 'AppLovinMediationChartboostAdapter', '9.4.0.0'
  pod 'AppLovinMediationFacebookAdapter', '6.14.0.0'
  pod 'AppLovinMediationGoogleAdapter', '10.9.0.1'
  pod 'AppLovinMediationIronSourceAdapter', '7.4.0.0.1'
  pod 'AppLovinMediationUnityAdsAdapter', '4.8.0.1'
  pod 'AppLovinMediationVungleAdapter', '7.0.1.0'
  pod 'AppLovinSDK', '11.11.2'
  pod 'FBSDKCoreKit', '~> 16.0'
  pod 'FBSDKCoreKit_Basics', '~> 16.0'
  pod 'FBSDKGamingServicesKit', '~> 16.0'
  pod 'FBSDKLoginKit', '~> 16.0'
  pod 'FBSDKShareKit', '~> 16.0'
end
target 'Unity-iPhone' do
end
use_frameworks! :linkage => :static

Changing: 'FBAudienceNetwork', '~> 6.4.1' to 'FBAudienceNetwork', '~> 6.14.0' to match the AppLovin Facebook Adaptor version also worked. Either way, these changes seem to correctly generate the required pod.

After making these changes to the Podfile, I run pod update to install the pods and generate the workspace file.

Open the workspace file (Unity-iPhone.xcworkspace), not the Xcode file (Unity-iPhone.xcodeproj) to open the project in Xcode.

Next, I had to manually drag and drop the Facebook SDK pod frameworks into the Unity-iPhone project:

Finally, after all of these steps, I was able to compile the build and run it on my iOS device without crashing on start.

Hope this helps!

yoambulante · 2023-08-23T14:08:23Z

yes, this worked for me too, adding manually the FB* pods to the project

Hi,
I'm facing the same issue and this workaround works for me as well. But one problem: have you succeed to make this process automatically? It’s not a good idea to insert a manual step into the automated build process.

Any idea? Thank you.

First, I changed my iOS Resolver settings to the following:

These settings are different from what AppLovin's integration instructions recommend, but it was the only way I managed to get things working.
My FacebookSDK > Plugins > Editor > Dependencies.xml file looks like this:
<?xml version="1.0" encoding="utf-8"?>
<dependencies>
    <androidPackages>
        <androidPackage spec="com.parse.bolts:bolts-android:1.4.0" />
        <androidPackage spec="com.facebook.android:facebook-core:[16.0,17)" />
        <androidPackage spec="com.facebook.android:facebook-applinks:[16.0,17)" />
        <androidPackage spec="com.facebook.android:facebook-login:[16.0,17)" />
        <androidPackage spec="com.facebook.android:facebook-share:[16.0,17)" />
        <androidPackage spec="com.facebook.android:facebook-gamingservices:[16.0,17)" />
    </androidPackages>
    <iosPods>
        <iosPod name="FBSDKCoreKit_Basics" version="~> 16.0" />
        <iosPod name="FBSDKCoreKit" version="~> 16.0" />
        <iosPod name="FBSDKLoginKit" version="~> 16.0" />
        <iosPod name="FBSDKShareKit" version="~> 16.0" />
        <iosPod name="FBSDKGamingServicesKit" version="~> 16.0" />
    </iosPods>
</dependencies>
After building the project to iOS, it generates a Podfile looking like this:
source 'https://cdn.cocoapods.org/'
platform :ios, '12.0'

target 'UnityFramework' do
  pod 'AppLovinMediationAdColonyAdapter', '4.9.0.0.4'
  pod 'AppLovinMediationByteDanceAdapter', '5.4.0.7.0'
  pod 'AppLovinMediationChartboostAdapter', '9.4.0.0'
  pod 'AppLovinMediationFacebookAdapter', '6.14.0.0'
  pod 'AppLovinMediationGoogleAdapter', '10.9.0.1'
  pod 'AppLovinMediationIronSourceAdapter', '7.4.0.0.1'
  pod 'AppLovinMediationUnityAdsAdapter', '4.8.0.1'
  pod 'AppLovinMediationVungleAdapter', '7.0.1.0'
  pod 'AppLovinSDK', '11.11.2'
  pod 'FBAudienceNetwork', '~> 6.4.1'
  pod 'FBSDKCoreKit', '~> 16.0'
  pod 'FBSDKCoreKit_Basics', '~> 16.0'
  pod 'FBSDKGamingServicesKit', '~> 16.0'
  pod 'FBSDKLoginKit', '~> 16.0'
  pod 'FBSDKShareKit', '~> 16.0'
end
target 'Unity-iPhone' do
end
use_frameworks! :linkage => :static
However, I had to manually remove the pod 'FBAudienceNetwork', '~> 6.4.1' line to make Xcode happy. So my final Podfile looks like this:
source 'https://cdn.cocoapods.org/'
platform :ios, '12.0'

target 'UnityFramework' do
  pod 'AppLovinMediationAdColonyAdapter', '4.9.0.0.4'
  pod 'AppLovinMediationByteDanceAdapter', '5.4.0.7.0'
  pod 'AppLovinMediationChartboostAdapter', '9.4.0.0'
  pod 'AppLovinMediationFacebookAdapter', '6.14.0.0'
  pod 'AppLovinMediationGoogleAdapter', '10.9.0.1'
  pod 'AppLovinMediationIronSourceAdapter', '7.4.0.0.1'
  pod 'AppLovinMediationUnityAdsAdapter', '4.8.0.1'
  pod 'AppLovinMediationVungleAdapter', '7.0.1.0'
  pod 'AppLovinSDK', '11.11.2'
  pod 'FBSDKCoreKit', '~> 16.0'
  pod 'FBSDKCoreKit_Basics', '~> 16.0'
  pod 'FBSDKGamingServicesKit', '~> 16.0'
  pod 'FBSDKLoginKit', '~> 16.0'
  pod 'FBSDKShareKit', '~> 16.0'
end
target 'Unity-iPhone' do
end
use_frameworks! :linkage => :static
Changing: 'FBAudienceNetwork', '~> 6.4.1' to 'FBAudienceNetwork', '~> 6.14.0' to match the AppLovin Facebook Adaptor version also worked. Either way, these changes seem to correctly generate the required pod.
After making these changes to the Podfile, I run pod update to install the pods and generate the workspace file.
Open the workspace file (Unity-iPhone.xcworkspace), not the Xcode file (Unity-iPhone.xcodeproj) to open the project in Xcode.
Next, I had to manually drag and drop the Facebook SDK pod frameworks into the Unity-iPhone project:

Finally, after all of these steps, I was able to compile the build and run it on my iOS device without crashing on start.
Hope this helps!

Hi, I'm facing the same issue and this workaround works for me as well. But one problem: have you succeed to make this process automatically? It’s not a good idea to insert a manual step into the automated build process.

Any idea? Thank you.

This code will link the Frameworks.
Improvements that could be made to the code is getting the framework names and locations automatically instead of hardcoded so it doesn't break in the future.
Most of the names were in the pod file but I didn't see FBAEMKit in the podfile

Expected behaviour:

Find the library and run

Other information

The project worked fine with Firebase before importing Facebook SDK.
Unticking Link frameworks statically has not worked for me
The build worked with Android, though it wasn't also straightforward (include "enableJetifier = true" https://forum.unity.com/threads/androidx-vs-android-libraries.710831/)
This is the pods file:

source 'https://cdn.cocoapods.org/'

platform :ios, '12.0'

target 'UnityFramework' do
  pod 'FBSDKCoreKit', '~> 16.0.1'
  pod 'FBSDKCoreKit_Basics', '~> 16.0.1'
  pod 'FBSDKGamingServicesKit', '~> 16.0.1'
  pod 'FBSDKLoginKit', '~> 16.0.1'
  pod 'FBSDKShareKit', '~> 16.0.1'
  pod 'Firebase/Analytics', '10.22.0'
  pod 'Firebase/Auth', '10.22.0'
  pod 'Firebase/Core', '10.22.0'
  pod 'Firebase/Database', '10.22.0'
end
target 'Unity-iPhone' do
end
use_frameworks! :linkage => :static

Since this bug has more than 1.5 year and there isn't any update in the SDK since August 2023 I was wondering if the support of Facebook for Unity has officially been cancelled?
