What are the advantages of using an editor instead of an Xcode?

"In the first place, ""very difficult to use"" is an individual's subjectivity, so I think it depends on each person whether or not they can make progress by changing to a different editor."
Also, I'm not used to Xcode. For example, I've used VS Code for development, so keyboard commands are just ingrained in my body.

If you're just writing a code, it means that you may be able to work with a familiarly without stress.On the other hand, I think people who start programming from Xcode will be confused even if they are suddenly told to write a program with VS Code.
By the way, I rely a lot on code supplementation, so I think I will use Xcode even if the operation becomes too slow to list the supplementary candidates.

Also, programming is not done by writing code, so I think it will be difficult to do complicated debugging work without Xcode.It's just a tool, so I think it's good to be particular about what to use, but I don't think you need to trust other people's opinions unconditionally.

If you don't have an editor that you're familiar with right now, you can use Xcode without worrying about it.
If you find the Xcode editor difficult to use, try another one.
