In earlier versions of XCode the folders in which the builds were done were in the project directory. In XCode4 these have disappeared. In the project and target build settings the builds are supposed to be in project/build/Debug and Release. According to Quick Help for build settings: "The path at which all products will be placed when performing a build. Typically this path is not set per target, but is set per-project or per-user. By default, this is set to $(PROJECT_DIR)/build. [SYMROOT]". I need to access these to make sure that dragging and dropping the application's file type to launch the app, etc. will work with my sandbox entitlements correctly. My guess is that XCode 4 makes these invisible. I can't figure out how to make them visible using the finder or by using XCode behaviors or preferences. In older versions of XCode I could build an unlocked app and put it in my applications folder to test it but in XCode 4 / OS X 10.7, when I double click on a file in the app's native file format it will open the app in the (invisible?) build folder. How can I access these folders?
