Run a shell script before build in Xcode

Question

I need to adjust my build and version number for my project before build/archiving.
I tried multiple things, but so far to no avail.

I added a target with the sc

Answer 1

Xcode has command line tools for build/archiving: https://developer.apple.com/library/ios/technotes/tn2339/_index.html

So, you can write shell script that at first runs your script for adjusting build/version number and then runs xcode build/archive as command line tool.

Answer 2

agvtools just does not work in an Xcode build. It will always stop the build. What works fine is PlistBuddy, although the setup is not as nice and neat.

I added a Pre-Action to the build in my main scheme to call a new target in my project:

xcodebuild -project "${SRCROOT}/MAIN_APP.xcodeproj" -scheme BuildNumberPreProcess

In the target BuildNumberPreProcess I have a Run Script:

VERSION=$(head -n 1 version.txt)
BUILD=`git rev-list $(git rev-parse --abbrev-ref HEAD) | wc -l | awk '{ print $1 }'`

echo "${VERSION} (${BUILD})"

SCRIPT="${SRCROOT}/CLIENT/Supporting Files/set-version-in-plist.sh"

"${SCRIPT}" "${SRCROOT}/MAIN_APP/Supporting Files/Info.plist" ${VERSION} ${BUILD}
"${SCRIPT}" "${SRCROOT}/EXTENSION/Info.plist" ${VERSION} ${BUILD}
...

set-version-in-plist.h:

#!/bin/sh

#  set-version-in-plist.sh
#
# usage:
# set-version-in-plist LIST VERSION BUILD
# LIST:      Info.plist path & name
# VERSION:   version number xxx.xxx.xxx
# BUILD:     build number xxxxx
#

# Location of PlistBuddy
PLISTBUDDY="/usr/libexec/PlistBuddy"

echo "$1: $2 ($3)"

${PLISTBUDDY} -c "Set :CFBundleShortVersionString $2" "$1";
${PLISTBUDDY} -c "Set :CFBundleVersion $3" "$1";
