问题
I'd really like to try El Capitan but I don't know if it is possible to run old Xcode on it, because it is critical for me now. Has anyone tried it?
回答1:
xCode 6.3.2 does run on the first El Capitan beta. I have tried building and running a swift app, this worked just like it should.
Although using xCode 6.3.2 does work on the first (and second) El Capitan beta. There might be some extra steps involved.
Submissions to the App Store will be rejected! if you are using a beta version of OSX
回答2:
Run this command on Terminal:
/Applications/Xcode.app/Contents/MacOS/Xcode /dev/null

I've created a shell script that you can run once to enable you to use Xcode 6.x normally on El Capitan (i.e., clickable without having to resort to launching via the terminal everytime).
As mentioned by others, you can not submit apps built on El Capitan while it's still in Beta.
Script is here: http://bit.ly/Xcode6OnElCapitan
