This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.

I already have Xcode installed on my Mac, I want to install the newer iPhone SDK.
Should I uninstall the older Xcode and install the newer SDK? or simple run the newer SDK?
The install of the latest version will take care of everything. No need to remove first.
