I am implementing FB Login so i Downloaded the SDK from https://developers.facebook.com/docs/ios.
then i drag n down
"FBSDKCoreKit/FBSDKCoreKit.h not found error"
Make sure to follow this step:
Deselect Copy items into destination group's folder. https://developers.facebook.com/docs/ios/getting-started/
Also, in your Build Settings, look at this field: "Framework Search Paths" You should have something like this: /Users/[username]/Documents/FacebookSDK
Also, look at Finder and make sure that the framework is actually there
