How to auto-increment Bundle Version in Xcode 4? - ios

Question

I am trying to figure out how to have the Bundle version number increment automatically in my Xcode 4 project (for ad-hoc and release builds). I found some scripts online that purport to do this but I am unsure of whether to place them in the "Pre-actions" or "Post-actions". I also am unsure what value I should place in the plist; a number that the script will then change or a variable?
All the options that I have tried thus far do not seem to work so any help would be greatly appreciated.
Below is the most recent script I was attempting to use:
conf=${CONFIGURATION}
arch=${ARCHS:0:4}
# Only increase the build number on Device and AdHoc/AppStore build
if [ $conf != "Debug" ] && [ $conf != "Release" ] && [ $arch != "i386" ]
then
buildPlist=${INFOPLIST_FILE}
buildVersion=$(/usr/libexec/PlistBuddy -c "Print CFBuildVersion" $buildPlist)
buildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBuildNumber" $buildPlist)
buildNumber=$(($buildNumber + 1))
/usr/libexec/PlistBuddy -c "Set :CFBuildNumber $buildNumber" $buildPlist
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildVersion.$buildNumber" $buildPlist
/usr/libexec/PlistBuddy -c "Set :CFBundleShortVersionString $buildVersion.$buildNumber" $buildPlist
fi

Answer 1

1, Set CFBundleVersion to 1.0.1 or something like x.x.x
2, Add build phases to run shell script autoVersion.sh
3, save below script named autoVersion.sh
#!/bin/sh
# Auto Increment Version Script
# set CFBundleVersion to 1.0.1 first!!!
# the perl regex splits out the last part of a build number (ie: 1.1.1) and increments it by one
# if you have a build number that is more than 3 components, add a '\.\d+' into the first part of the regex.
buildPlist=${INFOPLIST_FILE}
newVersion=`/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$buildPlist" | /usr/bin/perl -pe 's/(\d+\.\d+\.)(\d+)/$1.($2+1)/eg'`
#echo $newVersion;
/usr/libexec/PListBuddy -c "Set :CFBundleVersion $newVersion" "$buildPlist"
4, run shell: cp autoVersion.sh ~/Documents/ and chmod 777 ~/Documents/autoVersion.sh
5, Build & Enjoy it. :)

Answer 3

The same idea as Alix's answer, but much simpler:
buildNumber=`/bin/date +%Y%m%d%H%M%S`
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "${PROJECT_DIR}/${INFOPLIST_FILE}"
Add this as a Run Script item on Build Phases on your Target. This has the advantage of being monotonically increasing as well.

For anyone wanting to integrate version incrementing into a command line build script (perhaps for continuous integration), see the following commands:
# cd into the project folder containing the plist
cd /Users/waitea/iOS/E.ON/iOS/trunk/Eon
# grab the version numbers
major_version=$(grep -C 2 CFBundleVersion App-Info.plist | grep -o '[0-9]\+.[0-9]\+.[0-9]\+')
major_version_min=$(echo $major_version | grep -o '[0-9]\+.[0-9]\+\.')
minor_version=$(echo $major_version | grep -o '[0-9]\+$')
# increment the minor version
increment=`expr $minor_version + 1`
incremented_whole_version="$major_version_min$increment"
# replace the build number in the plist using perl
/usr/bin/perl -p -i -e "s/$major_version/$incremented_whole_version/g" App-Info.plist
That will increment the rightmost number in a x.x.x style version number. Tweak the reg-ex's to alter for your convention.
Took me a while so I thought I'd share to give back to the community!
EDIT - I created a continuous integration system that'll do this for you

I've found that using tiered xcconfigs helps this problem.
Working on complex builds with apps, libraries, and SDKs you have to be able to coordinate not merely build numbers per project, but build number compatibility.
You can make a build management header that is effectively a text file with build iteration numbers (or versioning info i.e. beta, dev, rel) and import it through the xcconfig import chain per project.
At that point you can have a target build script step that will embed your build/versioning info. This is also best done by putting holding text in your plist and running PlistBuddy on your derived file/built file sections. (This way your source control changes are minimal)
If you can write a build execution script that does the necessary build number twiddling (or better yet, use a system like bamboo which creates the file for you), you can keep that separate from your code. Granted, if you need to do it and keep track, you may have to check in the changed build number to allow it to increment.
I've been able as a result of this to maintain build numbers along the line of:
2.0.3 b34 (3473) Where we have a build number and an SVN checkout build point.
(Please no git hazing, I'm old school)
Pre/Post actions are more for Uber notifications or processes:
Email that the build started/failed/ etc
Copy the done project to the done project server.
Everything else works better as a Build Script.
(And as always: make the script phase call an external script file. DON'T push your script into the project, it's hell on source controlling the project file)
Hope this helps.

FWIW - this is what I'm currently using to increase the build number only for release builds (which includes archiving). Works fine under Xcode 5.1.
Just copy/paste the snippet into a Run script build phase directly in Xcode:
buildnum=$(/usr/libexec/PlistBuddy -c "Print :CFBundleVersion" "$PRODUCT_SETTINGS_PATH")
if [ "$CONFIGURATION" = "Release" ]; then
buildnum=$((buildnum + 1))
echo "Build number updated to $buildnum"
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildnum" "$PRODUCT_SETTINGS_PATH"
fi;

Answer 8

If you're using a version system like "x.x.x" you can add this run script. It'll increase the version number (x.x.x+1) every time a new build is made:
if [ "${CONFIGURATION}" != "Debug" ]; then
VERSIONNUM=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "${PROJECT_DIR}/${INFOPLIST_FILE}")
NEWSUBVERSION=`echo $VERSIONNUM | awk -F "." '{print $4}'`
NEWSUBVERSION=$(($NEWSUBVERSION + 1))
NEWVERSIONSTRING=`echo $VERSIONNUM | awk -F "." '{print $1 "." $2 "." $3 ".'$NEWSUBVERSION'" }'`
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $NEWVERSIONSTRING" "${PROJECT_DIR}/${INFOPLIST_FILE}"
fi

Answer 9

I haven't found a great solution for Xcode 10.1. I have modified some scripts to reach the goal. And everything now works fine.
version=$(/usr/libexec/PlistBuddy -c "Print :CFBundleShortVersionString" "${INFOPLIST_FILE}")
build=$(/usr/libexec/PlistBuddy -c "Print :CFBundleVersion" "${INFOPLIST_FILE}")
/usr/libexec/PlistBuddy -c "Set :PreferenceSpecifiers:1:DefaultValue ${version}" "${CODESIGNING_FOLDER_PATH}/Settings.bundle/Root.plist"
