I found an old version of Xcode 4.3 on one of my backup disks and dragged a copy:
/Developer/SDKs/MacOSX10.6.sdk
at
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.6.sdk
Now he sits along the sides MacOSX10.7.sdkand MacOSX10.8.sdkthat were already there. They came with Xcode 4.4.
I am running Xcode Version 4.4 (4F250) and OS X 10.8.
After restarting Xcode, do not forget to go to the build settings and install the base SDK in OS X 10.6, if it is "Current OS X" by default, and your project requires 10.6 sdk.
