Caio: Next question, “what is mandatory to have…” “on my iOS dev website, blog or channel?” Number one, amazing content, of course. Your contact details, so other developers or companies can talk to you. So, your email address should be there… your social media links. Maybe even a phone number if that makes sense to you. And you can also add a mailing list form to collect email addresses from your followers. If you build a mailing list you can send your updates directly to your followers. To people that want to hear from you.
