firebase - Swift classes added after pods installed do not register modules -

i'm making in app involves firebase, , when add firebase project, pre-existing classes work fine. however, after adding firebase, whenever create new swift class (such new uiviewcontroller class) , import firebase modules in it:

import uikit import firebase //works in files created before pods installed...                  //...but not files created after  class newviewcontroller: uiviewcontroller {      override func viewdidload() {         super.viewdidload()          // additional setup after loading view.     }      override func didreceivememorywarning() {         super.didreceivememorywarning()         // dispose of resources can recreated.     } } 

the import statement throws "no such module firebase". classes added before still register import though. doing wrong, , how can fix this?

try this.

• clean derived data.
• do fresh pod install
• do clean build , build(cmd+b)
• now add import statement in class - import firebase , should start working.
