iOS Stable version of Xcode? 6.3 / 6.3.1

I just upgraded everything and went with Xcode 6.3. Now I hear that 6.3.1 is to fix 'critical issues' ...

All I care about is a functional stable system.

Is 6.3 solid? Has anyone upgraded to 6.3.1?

Although I've only read about Swift, is it stable now?

It feels like it's building / running faster, but that could just be me.

It's about as stable as it's going to be for the time being.

Ok, that sounds like good news. I'm mainly just concerned about being stable, I don't want to have to back grade.

It also sounds like they've released Swift 1.2, so I guess that's becoming pretty stable now, I'll have to dig into it.
