Build App for iOs without a Mac

I’m finishing a application using Ionic (Version: 3.20.0).
I’m already deploy to Android, but now i want to deploy to iOs.
I’ve seen this tutorial, but i dont if this works yet.
Anyone did this process recently?

I’m using Linux Ubuntu 16.04 LTS.

Impossible.

Try macincloud.com

I think macincloud is the only way to build iOS without mac.
