@luizpaulofranz try run the app in example/ and let me know how that works for you 🙏

And also, please let me know if you have searched for this issue in other contexts. I found this: facebook/facebook-ios-sdk#2121

[noinskit]

flutter_facebook_auth has the same problem: darwin-morocho/flutter-facebook-auth#302

It's not clear if it's fixed there, but flutter-facebook-auth is already running a newer version of the iOS native dependency, so current version of flutter-facebook-auth can't coexist with the newest flutter_facebook_app_events.

@DennisAlund I've just tried the example project with the same problem:

Xcode build done.                                           55.8s
(lldb) dyld[4578]: Library not loaded: @rpath/FBSDKCoreKit.framework/FBSDKCoreKit

[xalikoutis]

same for me IOS crashes

[luizpaulofranz]

Hey guys, a temporary workaraound for this can be found in that link sent by @DennisAlund above: facebook/facebook-ios-sdk#2121

This is working here:

"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."

I believe that happens only if you compile x86 mac for release. I just changed codemagic builds to mac_m1 and it is working

[zeucxb]

Just import FBSDKCoreKit and FBSDKCoreKit_Basics solved 🙌🏼

[Gloomy699]

need to upgrade FBSDKCoreKit up to 15.1.0 https://cocoapods.org/pods/FBSDKCoreKit because FBSDKCoreKit version in package is 15.0.0 it`s work for me.

[DennisAlund]

FBSDKCoreKit was just updated to 15.1 so we'll close it for now if that was a solution. Please re-open if the problem persists.
