Auto Increment Build Number in Xcode

March 31st, 2014

This is a great Copy-Paste solution for every solo iOS Developer. It automatically increases the build number of your Xcode project every time you Run your program.

Two Facts:

  1. You now have a reason to have a build number.
  2. You will spend less than a minute on this. And never worry about it again.

Go to your Project’s Build Phases tab, and click the + button. Choose New Run Script Build Phase then drag the Phase to be second (after Target Dependencies).

In the space after the shell’s /bin/bash, copy this:

<code>#!/bin/bash
bN=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$INFOPLIST_FILE")
bN=$((0x$bN))
bN=$(($bN + 1))
bN=$(printf "%X" $bN)
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $bN" "$INFOPLIST_FILE"</code>

 

Works like a charm. Just make sure your build number starts as “1″ and not “1.0″. This great solution was originally posted by RobertL on Stack Overflow but I liked it so much I’m sharing it!

I think this would be particularly powerful if cleverly extended to work with version control.
