Development and designing is nearly same but with few differences in its phases or roles/ responsibilities.
Development Jobs need coding, debugging and testing whereas designing has to only show prototyping and coding.
In simple words, Both developer and designer have the same goal. Both job roles are required to finish a app or website or a product, etc. A designer provides the UI/UX design, its components,etc and the rough draft of its look and requirements,Whereas the developer is the main head to convert the design (prototype) to live. A designer necessary to know many languages and tools but a developer has many tools and languages to learn for different requirement and efficiency.
Development job is better if you are good in technical and programming skills otherwise designer job is better.
So Finally i would say that both are different.
