I just upgraded my pods for Firebase and got a ton of errors. I used the Docs on the Firebase Docs webpage so I was able to fix most of them. This error I\'m stuck on and ne

Answer 1

If you look at the release notes you see they changed some stuff. Essentially instead of returning a user, they now return another object (AuthDataResult) containing a user.

This means you need to a FIRAuthDataResultCallback.

Answer 2

Database5 is change a lot of syntax,

In error1, you can try this:

static func signUp(username:String, email:String, password: String, imageData:Data, onSuccess: @escaping () -> Void, onError: @escaping (_ errorMessage: String?) -> Void) {
    Auth.auth().createUser(withEmail: email, password: password) { (user , error) in
        if error != nil {
            onError(error!.localizedDescription)
            return
        }
        //Here you have to change the uid 
        let uid = user?.user.uid
        //It should be Storage.storage().reference()
        let storageRef = Storage.storage().reference(forURL: Config.STORAGE_ROOT_REF).child("profile_image").child(uid!)
        //storageRef.put was removed and it's changed be storage.putData 
        storageRef.putData(imageData, metadata: nil, completion: { (metadata, error) in
            if error != nil {
                return
            }
            //downloadURL is changed too, you can read at documents of Firebase to know how to use this
            storageRef.downloadURL(completion: { (url, error) in
                if let error = error { 
                    return
                }else {
                    let profileImageUrl = url!.absoluteString
                    self.setUserInformation(profileImageUrl: profileImageUrl, username: username, email: email, uid: uid!, onSuccess: onSuccess)
                }
            })
        })
    }
}

And in error2, it same error with error1, you can try this:

        Api.User.CURRENT_USER?.updateEmail(to: email, completion: { (error) in
        if error != nil {
            onError(error?.localizedDescription)
        }else {  
            let uid = Api.User.CURRENT_USER?.uid
            //Change here
            let storageRef = Storage.storage().reference(forURL: Config.STORAGE_ROOT_REF).child("profile_image").child(uid!)
            //Change here
            storageRef.putData(imageData, metadata: nil, completion: { (metadata, error) in
                if error != nil {
                    return
                }
                storageRef.downloadURL(completion: { (url, error) in
                    if let error = error {
                        return
                    }else {
                        let profileImageUrl = url!.absoluteString
                        self.updateDatabase(profileImageUrl: profileImageUrl, username: username, email: email, onSuccess: onSuccess, onError: onError)
                    }
                })
            })
        }
    })


static func updateDatabase(profileImageUrl: String, username: String, email: String, onSuccess: @escaping () -> Void, onError: @escaping (_ errorMessage: String?) -> Void) {
    let dict = ["username": username, "username_lowercase": username.lowercased(), "email": email, "profileImageUrl": profileImageUrl]
    Api.User.REF_CURRENT_USER?.updateChildValues(dict, withCompletionBlock: { (error, ref) in
        if error != nil {
            onError(error?.localizedDescription)
        }else {
            onSuccess()
        }
    })
}


static func logOut(onSuccess: @escaping () -> Void, onError: @escaping (_ errorMessage: String?) -> Void) {
    do {
        try Auth.auth().signOut()
        onSuccess()
    }catch let logoutError {
        onError(logoutError.localizedDescription)
    }
}

You can read document of Firebase again to see what difference https://firebase.google.com/docs/ios/setup
