Xcode 6.3.2 can't run on OSX 10.11 El Capitan Developer Preview 3

Question

I'm just updated my Mac to OS X 10.11 El Capitan DP 2, and I disappointed that it does not support Xcode 6.3.2

Now, how do I work? I have a project to do, and it's not a good time to convert my project to Swift 2/Xcode 7 since it's impossible to submitting at this time?

Answer 1

Open terminal and use this command

/Applications/Xcode.app/Contents/MacOS/Xcode </dev/null &>/dev/null &

Answer 2

From the El Capitan release notes:

Xcode versions prior to 7 are not supported on OS X El Capitan Beta 3

And from the Xcode 7 beta 4 release notes:

Xcode 6.x has known compatibility issues when run on OS X version 10.11 El Capitan. It is strongly encouraged that you use Xcode 7 when running on OS X El Capitan.

I know it doesn't help you much now, but as a general rule of thumb, I recommend not upgrading anything in your build process if you're on a deadline and you can't easily revert.
