Facebook SDK is not a dylib

Question

I am attempting to build a project I did not write, and I keep reaching this error:

ld: warning: Auto-Linking supplied '/Users/my_user_name/Documents/FacebookSDK/FBSDKCoreKit.framework/FBSDKCoreKit', framework linker option at /Users/my_user_name/Documents/FacebookSDK/FBSDKCoreKit.framework/FBSDKCoreKit is not a dylib Undefined symbols for architecture x86_64: "_OBJC_CLASS_$_FBSDKAppEvents", referenced from: objc-class-ref in AppDelegate.o "_OBJC_CLASS_$_FBSDKApplicationDelegate", referenced from: objc-class-ref in AppDelegate.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

This is a new error since updating Parse and Bolts pods. Other solutions for Auto-Linking that I've seen on here have not been able to help, but since the update to Facebook SDK is new perhaps someone has already solved this issue.

Answer 1

It's because of the conflict between the reference of FB SDK located at /Users/my_user_name/Documents/ and the one in CocoaPods.

Originally I used FB SDK located at /Users/my_user_name/Documents/ as suggested in FB SDK Getting Started tutorial. Then switched to Cocoapods after I started using react-native.

The solution is to remove Facebook SDK references from your apps Frameworks folder in YourApp.xcodeproj. I have explained more at https://stackoverflow.com/a/36947791/556678.

Make sure you're using a current version of the FBSDK! Also make sure you followed THESE (new) instructions: https://parse.com/docs/ios/guide#users-facebook-users (because with the parse update different things must be done!).

If the problem persists, I suggest you build a new project (that follows the instructions in the previous link).
