Fix -> update versions to 5.8 in the dependencies.xml (Located at Assets -> Facebook SDK -> Plugins -> Editor):

<?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:[5,6)" /> <androidPackage spec="com.facebook.android:facebook-applinks:[5,6)" /> <androidPackage spec="com.facebook.android:facebook-login:[5,6)" /> <androidPackage spec="com.facebook.android:facebook-share:[5,6)" /> </androidPackages> <iosPods> <iosPod name="Bolts" version="~> 1.7" /> <iosPod name="FBSDKCoreKit" version="5.8" /> <iosPod name="FBSDKLoginKit" version="5.8" /> <iosPod name="FBSDKShareKit" version="5.8" /> </iosPods> </dependencies>

You, sir, are a hero. Thank you.

This fix does not work here, in a completely blank project with 7.18.0

In XCode there is still an error:

Library not found for -lFBSDKCoreKit

[digitalalcohol]

Facebook SDK actually has been failing on iOS and XCode since 7.17.0

7.18.0
Library not found for -lFBSDKCoreKit

7.17.0 - 7.17.2
Library not found for -IBolts

Who at Facebook tests their work? Anyone???

(Dependency editing did not solve it either — this should not be necessary with proper software engineering practices)

[koprivajakub]

I do have the build working with following versions:
Facebook SDK for Unity 7.18.0
Unity: 2019.4.15f1
XCode: 11.3

But my problem was in the Unity Cloud Build. Where I did get the very same error. My fix was to change (lock) the version of the iOS pod to 5.8.0

In Assets/FacebookSDK/Plugins/Editor/Dependencies.xml lock the FBSDK version to 5.8.0.

<?xml version="1.0" encoding="utf-8"?>
<dependencies>
    <iosPods>
        <iosPod name="FBSDKCoreKit" version="5.8.0" />
        <iosPod name="FBSDKLoginKit" version="5.8.0" />
        <iosPod name="FBSDKShareKit" version="5.8.0" />
    </iosPods>
</dependencies>

Is there an intention to fix the problem? Although it seems like a problem of Unity Cloud Build platform itself.

Thank you! Switching to 5.8.0 fixed it.

I had the same problem with 7.19.2 and putting it to 5.8.0 didn't work for me because of FBSDKGamingServicesKit.

I tried removing it and now I am building. Any tips would be greatly appreciated!

EDIT: Same happened with 7.17.2. Trying more versions...

[yaKashif]

@Nesh108 Did you find solution?
I am facing FBSDKGamingServicesKit.h not found issue. The framework doesn't even exists in the FacebookSDK. Using 7.21

[Nesh108]

My only "solution" was to stick to version 7.13.0 and that's it :(
