Resizing Behavior Button Missing From Xcode

Question

I have Xcode 6.3 installed on 3 Macs with the latest version of Yosemite and on every one of them the Resizing Behavior button is missing. I can't find any Preference or View setting to bring it back. I've scoured the internet, but I can't find anyone with a similar issue. I've uninstalled and reinstalled Xcode with no joy.

Anyone else have this issue?
