IDE Issues (help a newbie) [SOLVED]

Hello
I am learning c++ via unreal engine. My experience with both C++ and UE is very limited but I was thinking using IDE like VS2017 would help finding my way in this massive engine and programming language. Long story short, auto-complete never works. Often I have to find the necessary libraries and add them manually to make things work. Is there a way to make auto-complete better for a newbie?

Using VS2017 with UE 4.21

Yes you definitely need to get the Visual Assist Plugin. The built in auto-complete can be made a bit quicker but Visual Assist is just quicker and more convenient.

thank you very much both @SolidSk and @GarnerP57
