I can also confirm this issue with iOS SDK 5.14.0. Version 5.13.1 seems to work just fine.

To fix this I had to change the dependencies file in Unity from 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:[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="FBSDKCoreKit" version="~> 5.2" />
        <iosPod name="FBSDKLoginKit" version="~> 5.2" />
        <iosPod name="FBSDKShareKit" version="~> 5.2" />
    </iosPods>
</dependencies>

TO 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:[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="FBSDKCoreKit" version="~> 5.8.0" />
        <iosPod name="FBSDKLoginKit" version="~> 5.8.0" />
        <iosPod name="FBSDKShareKit" version="~> 5.8.0" />
    </iosPods>
</dependencies>

Same problem here,
changing the dependencies did not fix the problem.

Check your PodFile after Unity exports the project, also update your cocoapods and restart your mac and build again if it doesnt help

Command to update your pods - sudo gem install cocoapods

Check my other solution, maybe it will help you aswell :)

Aaaaand this solution doesn't work anymore, perfect!

I also have this exact same problem. Been 20 days or so since I made a build for iOS, I've changed nothing.

Updating cocoapods did not solve it

This issue happend with FBSDK 5.14 for iOS. Try either do the following to use 5.13 instead:

Change the FBSDK version to 5.13 in "Dependencies.xml" in the folder FacebookSDK/Plugins/Editor:

<iosPod name="FBSDKCoreKit" version="5.13" />
<iosPod name="FBSDKLoginKit" version="5.13" />
<iosPod name="FBSDKShareKit" version="5.13" />

In Xcode project, change the FBSDK to 5.13 in the "Podfile" to the following and run "pod install" in the command line inside Xcode project folder

pod 'FBSDKCoreKit', '5.13'
pod 'FBSDKLoginKit', '5.13'
pod 'FBSDKShareKit', '5.13'

pod 'FBSDKShareKit', '5.13'

Unfortunately that didn't work for me. I edited my dependencies script in unity as you mentioned

iosPods
    iosPod name="FBSDKCoreKit" version="~> 5.13" 
    iosPod name="FBSDKLoginKit" version="~> 5.13" 
    iosPod name="FBSDKShareKit" version="~> 5.13" 
iosPods

@Fudds The latest 5.15 has fixed this issue. Just run "pod repo update" before exporting XCode to build.

@jzhudev pod repo update brought it to 5.15 and fixed my problem.

Thanks for the help!
