Hello,

Xcode 6 is discontinued since long and can't even be run on current OS X version. Moreover, Xcode 8 is just 6 weeks away. You know, Apple is relentless (and remorseless) in its upgrade cycle.

On the other hand, upgrading from Xcode 6 to 7 should be relatively straightforward. Is there a particular reason you need to remain on Xcode 6?

Best regards,

Gianluca
