Xcode is very slow. Every time that I open it, my computer switch on the cooler, the memory of my mac have a spike of consuming. I don't like the IDE itself... for instance, if I need to rename something, Xcode uses an XML that when you have a team working on the same project, you will have huge problems with merge the commits. Maybe the problem is me, but, I know XCode since 2012 and I never like it! =l
