UIKit / UIKit.h not found on Facebook Notification SDK (FBNotification) [closed]

I'm trying to compile my project, but after a long time without opening it, I started getting an error about FBNotification SDK.

The message is:

  

In-file included from /Users/paulo/Developer/workspaces/xcode/xyz-ios-swift/Pods/FBNotifications/iOS/FBNotifications/FBNotifications/Internal/Models/Components/FBNAnimatedImage.m:19:

  fatal error: 'UIKIt / UIKit.h' file not found

     

import UIKIt / UIKit.h
  --------- ^ ~~~~~~~~~~~~~~
  1 error generated.

Can anyone help me with it?

Thanks.
