Using Xcode 10.1, Swift 4.2 and Firebase ##

I can't see datas in my realtime database after uploading the datas to firebase with the following code:

static func createUser(username: String, email: String, password: String, imageData: Data, onSuccess: @escaping () -> Void, onError: @escaping (_ error: String?) -> Void) {



    Auth.auth().createUser(withEmail: email, password: password) { (data, error) in

        if let err = error {

            onError(err.localizedDescription)

            return

        }

        // User erfolgreich erstellt

        guard let uid = data?.user.uid else { return }

        self.uploadUserData(uid: uid, username: username, email: email, imageData: imageData, onSuccess: onSuccess)

    }

}



static func uploadUserData(uid: String, username: String, email: String, imageData: Data, onSuccess: @escaping () -> Void) {





    let storageRef = Storage.storage().reference().child("profile_image").child(uid)



    storageRef.putData(imageData, metadata: nil) { (metadata, error) in

        if error != nil {

            return

        }

    }



    storageRef.downloadURL(completion:  { (url, error) in

        if  error != nil {

            print(error!.localizedDescription)

            return

        }



        let profilImageURL = url?.absoluteString





        let ref = Database.database().reference().child("users").child(uid)

        ref.setValue(["username" : username, "email" : email, "profileImageURL": profilImageURL ?? "Kein Bild vorhanden"])



    })

     onSuccess()

}

The settings in firebase:

Should work the right way. I already looked at the firebase documentation and didn't find more informations.

Does the image get uploaded to Cloud Storage? If it does but the download URL isn't written to the database, my guess is it's because the data isn't uploaded before you generate the download URL. Since the upload function is asynchronous, the downloadURLfunction should be called from the closure.

static func uploadUserData(uid: String, username: String, email: String, imageData: Data, onSuccess: @escaping () -> Void) {



    let storageRef = Storage.storage().reference().child("profile_image").child(uid)



    storageRef.putData(imageData, metadata: nil) { (metadata, error) in

        if error != nil {

            return

        }

        storageRef.downloadURL(completion:  { (url, error) in

        if  error != nil {

            print(error!.localizedDescription)

            return

        }

     onSuccess()

    }

}
