Does anyone have a link to an up-to-date tutorial on how to manage the Build Settings for Xcode 4? I am completely lost. I thought Xcode 3 was bad enough, but I do not understand the build setting screens at all in Xcode 4. How do I associate specific build settings with debug, release, and archived versions of my code? The Project -> Info screen shows the Debug and Release options but then associates a "Configuration File" which by default is "None". What is a Configuration File? Also, when moving to the Build Settings screen the context is lost as it reverts to Resolved, Target, Project, and Default levels -- where is the context of Debug or Release indicated? And on top of all that I get buttons in the editor that say "My Mac (64-bit)" which again is confusing as nowhere in the Build Settings did I see anything that is labeled such. So what is "My Mac (64-bit)" using for the build settings other than 64-bit compilation? Is it debug or release? Thanks for any tips.
