Xcode regularly crashes and/or ends up leaving garbage in its garbage xml files. The un-reviewable xml stuff is also a garbage of its own making. The build system is intractable. Xcode does not lend itself to segregating builds from dependency fetching, i.e. do all the internet things on one machine and donthe building on a different one. The debugger cocks out at least weekly. Sure, you can make goods app with it. We’ve been making good apps with less for decades too. Other platforms/editors are not as painful, it is as simple as that.

The only thing XML Xcode generates are storyboards and xibs (and schemes also). All of those XMLs are readable. Xcode’s build system is very reasonable (though different than on other IDEs, but that does not mean bad!).

How interesting! Xcode very rarely crashes on me. I don't know why but it seems to work 99.9% of time the way I expect it to work. Its build system makes sense to me. Of course, it differs from other build systems but that's life, I am flexible and can learn things. Just saying.
