Working on a Mac / iOS projects, I have been trying to come up with an easy way to bump versions when it goes out the door for testing or production. Mostly I have been working it out manually, yet that is now fun after the dozenth time. I started looking around for something that would fit my workflow. I found a couple of posts that help me out.
After reading the two posts (especially the last one), it should be easy to follow what I am doing to bump the versions of the application. It feels natural with the gitflow technique. Download the code from the GitHub project here.
