Upgrading to Mountain Lion - ParkinT/RubyMotion_Life GitHub Wiki

Kenneth Nordahl upgraded to the GM version of Mountain Lion the other day. Xcode 4.3 is not compatible with the new OSX version so I had to install Xcode 4.5 beta. The new Xcode configured itself as the default version on its first run which resulted in a broken rubymotion rake command.

With help from Laurent he was able to switch back to the old 4.3 Xcode to run and compile my rubymotion project with the following command:

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
