If you use multiple pod projects
install! 'cocoapods',
:generate_multiple_pod_projects => true
Then you should force cocoapods to put all of FBSDK pods into a same project to make private headers visible
pod 'FBSDKCoreKit', '5.11.0', :project_name => 'FBSDK'
pod 'Bolts', '1.9.0', :project_name => 'FBSDK'
pod 'FBSDKShareKit', '5.11.0', :project_name => 'FBSDK'
pod 'FBSDKLoginKit', '5.11.0', :project_name => 'FBSDK'
