Customizing Xcode Text Macros

Students in our classes often ask how to customize Xcode’s text macros for block structured statements (e.g., method and function bodies, bodies of if, for, and while statements, etc.) in order to push the opening curly brace to the next line. Here’s a little command-line fu using OS X’s defaults mechanism:

defaults write com.apple.Xcode XCCodeSenseFormattingOptions '{ "BlockSeparator" = "\n" ; }'

This tells Xcode to use a newline character as the ‘block separator’ between the opening curly brace and whatever preceded it.
