The short answer to this question is NO.

It can be useful but is in no way essential.

I will throw more light in a bit but first, let's get this clear.

User interface design, user experience design and coding are three different things.

A UI and UX designer do not depend on coding skill to carryout their jobs any more than a mechanic also need to know how to drive a car.

However, if you can drive as a mechanic, you will be able to communicate with drivers about their problems better.

So also as a designer that knows about coding, it will be much easier to communicate and work with developers.

Having a knowledge of coding will also give you a competitive advantage when you enter the job market.

If you are wondering what codes to learn, I suggest you learn the basics of HTML, CSS, and Javascript.

Hope this cools your mind.
