No. It. Doesn't.
The whole conversation came from someone claiming the most basic feature of an IDE is to include a terminal - that's why people are discussing terminals.
Don't get me wrong, I live in the terminal when using the computer, but I don't see a need for one when using Xcode.
Call it a task runner shell, if you like. What makes a development environment integrated, if not the ability to launch and manage external processes?
