This technique is based on Jeff Verkoeyen’s method . I find that modifying .xcodeproj files to be rather inconvenient so I whipped up a Rakefile that can be easily copied and pasted into new projects:
# This assumes you have placed your public header files in the `Headers`
# directory in your output directory. You can satisfy that easily by creating a
# "Copy Files" build phase. See
# http://image.bayimg.com/9cf4804007f7a7b59505de345ad2bbc388499475.jpg
# Usage:
#
# 1. Change `PROJECT_NAME` below. E.g. if you have `Calculator.xcodeproj`, change it to `"Calculator"`
# 2. Put this beside your `.xcodeproj` file, then just run `rake`
