after update firebase 4.0.4 got error, here whole codes :

now have 2 errors :

here errors

i tried update profilechangerequest() createprofilechangerequest() didn't help

here user class:

import foundation import firebase import firebasedatabase  struct user {     var username: string!     var email: string?     var country: string?     var biography: string?     var photourl: string!     var uid: string!     var ref: databasereference?     var key: string?       init(snapshot: datasnapshot) {          key = snapshot.key          ref = snapshot.ref          username = (snapshot.value! as! nsdictionary)["username"] as! string          email = (snapshot.value! as! nsdictionary)["email"] as? string          country = (snapshot.value! as! nsdictionary)["country"] as? string          uid = (snapshot.value! as! nsdictionary)["uid"] as! string          biography = (snapshot.value! as! nsdictionary)["biography"] as? string         photourl = (snapshot.value! as! nsdictionary)["photourl"] as! string      }   } 

i think user class clashing with firuser class changed firuser user in 4.x sdk. try renaming user class localuser , see if helps, if there's problem
