com.facebook.sdk.core error 8

Question

This is more informative than anything. I couldn't for the life of me find anything on error code 8 when trying to access the login prompt (aka safari) when debugging my ios app. After I hit the log into facebook button in my app it would attempt to open safari then dump me back to the login page to my app. The error was being caused by the permissions array. I had the the permission "public_profile" spelled "public profile" which was throwing an error obviously. So make sure your permission are type corrected if you get the com.facebook.sdk.core error 8.

Hope that helps someone.

Answer 1

Make sure your permissions are typed correctly

   func loginButton(loginButton: FBSDKLoginButton!, didCompleteWithResult result: FBSDKLoginManagerLoginResult!, error: NSError!) {              if error == nil {                 println("login complete")                 self.performSegueWithIdentifier("showLogin", sender: self)              }else{                  println(error.localizedDescription)     //com.facebook.sdk.core error 8.             }         } 

Answer 2

In my case this error was caused by improper bundle id set in facebook settings of the app itself. Facebook "bundle id" is case sensitive, in my Info.plist I had uppercase product name, but in fb settings - lowercase.
