I have been using Xcode for more than 5 years and this change is sadly the first change that is so bad that I am motivated to post in the Developer Forums for the first time. I've lived through buggy code and missing features but this is the first time where, through lack of design consideration and user experience, they've managed to cripple a key feature. These problem should have been flagged early in the dev cycle and is a problem of technical leadership rather than programming.
