You have To try this code...(After Authentication , You have to create display name ("Firstname + Lastname") inside mobile app using below mentioned code )

 if let currentUser = Auth.auth().currentUser {
    let changeRequest = currentUser.createProfileChangeRequest()
    changeRequest.displayName = "Firstname" + "Lastname"
    changeRequest.commitChanges(completion: { (error) in
        if let error = error {
            print("--> firebase user display name error:- ", error)
        }
    })
}

After completion of this code we got current user displayname.
