Steven Fisher with an interesting use case for Xcode snapshots. I switched this on when I read about it earlier this week and certainly haven't noticed any speed or other issues but I also haven't found myself going back to a snapshot either so they may still be as useless as they previously were.
Luke Redpath released an early version of a ruby gem this week for helping with the xcodebuild command line tool. I especially liked the way it tidies the xcodebuild output.
Talking of Xcode and the command line, this is another ruby script from Guillaume Cerquant which will generate a .ipa from an Xcode project and archive it along with the debug symbols. Neat.
