I downloaded the XCode 8 beta 5 GB file from deveoper.apple.com . Moved the .xip to Applications folder and then double clicked it. It just opens the Archive Utility and then shows a dialog with Verifying "Xcode_8_beta.xip" and pretty much hangs at that state. Unable to install the new Xcode. What am I missing here ?
Thanks,

I had the same issue, found this command which solved it:
xattr -d com.apple.quarantine Xcode-beta.appI had the same issue, found this command which solved it:
xattr -d com.apple.quarantine Xcode-beta.appOften this is helped with a simple reboot.
Sometimes you might not be stuck. It might just be taking a while because of other I/O on the system. However, if it really is stuck, please take a sysdiagnose and file a radar at http://bugreport.apple.com before you reboot.
Had the same problem. This helped. Great answer.
A reboot fixed this for me. Thanks.
I was having the same problem. I was running 10.11.5 of OS X. Based on a response at stackoverflow (see below), I did a reinstall from Recovery, and then xip worked correctly.

Could you advice if using
xattr -d com.apple.quarantine Xcode-beta.appis wrong ?
Yes. It is not recommended to use that command. It skips the signature verification process.
NO. THIS IS A WRONG ANSWER.
the only thing you have to put in the quarantine is your xip file which you have problems with while verifying. For example:
sudo xattr -d com.apple.quarantine Xcode_8_GM_seed.xipThis works! Thanks
This worked for me as well!
