Sorry for telling you the obvious, but .NET is used more on the server side and in desktop. iOS is mobile.

Which have you worked in more? frontend/backend/full stack OR desktop OR mobile? Which do you want to work in?

I worked full stack. Developed both server side and desktop side with C#. Consumed WCF services in iOS apps. I want to work in iOS development. But I am afraid of losing my experience for C#.
