FBSDKLoginManager: undefined symbols for architecture x86_64 + linker command failed with exit code 1

Question

I just upgraded Facebook iOS SDK to v.4.0.1 and I got these errors:

Undefined symbols for architecture x86_64:
  \"_OBJC_CLASS_$_FBSDKLoginManager\", referenced          


        

Answer 1

if you are trying to add it using cocoapods just add versions and it will work

change the pod file to the following:

pod 'FBSDKCoreKit', '~> 4.17.0'
pod 'FBSDKLoginKit', '~> 4.17.0'
pod 'FBSDKShareKit', '~> 4.17.0'
