Of course.

I don't have any knowledge of build systems or how to make things faster, but I do want to mention things that are important to my workflow that I hope this change won't make worse. I'm a little worried that this appears to be moving away from Xcode in a manner that will make development more difficult. Maybe I've misunderstood some of the suggestions.

I want to:

- be able to do most (all) of my editing in Xcode
- have code completion and symbol navigation work very nicely in Xcode
- build and run from Xcode
- build and run from Xcode much faster than I can today
- use Xcode's debugger UI
- sometimes have just a single project open in Xcode (e.g. WebCore) and build only that part (so I can skip it even having to think about other parts)

Will the new magic build system offer these? Will it break any of them?

If calling build can mean a new Xcode project is created, will I be able to open it and have a nice project structure, with the original files I want to edit, not the unified sources.
