El Capitan beta 6 + Xcode

Same here. Better wait for the next Xcode beta. Should be released tomorrow.

yep dead in the water let us know if reinstall work

Same issue here... Xcode 6 crashes when opening interface builder. Compilation also hangs on xib compilation... :s

os x beta 6 release notes:

Known Issues

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

Both Xcode 6.4 and 7 beta are broken here too.

I did reinstall Xcode-beta, it did not help.

I only have xcode 7b4. I was able to open a project and run it on my iPhone. This is on os x 10.11 beta 6 that installed today.

No! it still not working. Both.

Try editing a XIB or Storyboard.

Happens to me as well. Xcode 6.4 crashes immediately when launched.

Same issue here...

Someone told me in Twitter that the Xcode beta download page is down. Weird. Not for me. I'm in Brazil.

Well I'm screwed. I've got deadlines for iOS 9 apps, and iOS 8 apps. Most important iOS 8 is due tomorrow morning. I had upgraded to el capitan because of the iOS 9 requirements due at end of august.

Went to lunch and came back. Lovely. My mac updated automatically while i was at lunch. Must've hit some install update button I wasn't paying attention to.

PLEASE SOMEONE FIND A FIX FOR XCODE 6.X

Don't know if this is just an error for me or if it is the root cause of everyones problems, but I am getting cdtool cannot compile in ***.xcdatamodeld/***.xcdatamodel with beta 6 when I get lucky and my project decides to open without outright crashing. I am currently playing around with editing and removed the xcdatamodel file, will update if I find a solution.

To develop in xcode 6, partition your disk and put yosemite on one partition and el capitan on the other with 7. You will need to reboot in to the version you want to develop in the xcode you want.

Yup... Same here...

And opening my project in Xcode 7 is a no-go for me, because it asks me to convert all my code to Swift 2.0.

If anyone has a fix, I'll be glad to use it.

Definitely the problem is with storyboards/xib files. I tend to believe this is a bug because it's not a Xcode 6 thing only. If not, I hope tomorrow appears a working version of Xcode 6 in addition to the Xcode 7 new beta because it would be a disaster for me if not.

I'd be shocked if we got an Xcode 6 update. If you need 6 before the next ElCap beta, I'd suggest a partition with Yose or virtualized.

Same problem here. Clean reinstall of Xcode 7 but cannot build anything after installing El Capitan Beta 6.

This does appear to be an issue involving Interface Builder specifically. Funny enough, since beta6 actually fixes a fair number of layout issues for me... in code already compiled.

Same here, both broken. I'm gonna have a banana and wait. Why don't they release everything together?

Same here, both broken.

My Xcode 6.4 would crash after open the project. xcode 7 still work, but some xib could be open. unable to work now and want some solution.

The same here, Xcode-beta with el Capitan beta 6

In this thread, user Dev claims he's been able to fix it by reinstalling the OS. I'm still waiting for him to confirm if he indeed reinstalled beta 6 again.

If someone is willing/desperate enough to give this a go, let me know!
