How to automatically set the version and build number of a Watchkit app target

I use this to update all the targets:

#!/bin/bashbuildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$INFOPLIST_FILE")buildNumber=$(($buildNumber + 1))/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE"/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$SRCROOT/Great WatchKit App/Info.plist"

My CFBundleVersion is the number of commits on my master branch on the git repo.

On my main app target, in Build Phases > + New Run Script Phase I've added this script:

# Set the build number to the count of Git commitsbuildNumber=$(git rev-list --count HEAD)/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "${PROJECT_DIR}/${INFOPLIST_FILE}"/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$SRCROOT/app WatchKit Extension/Info.plist"/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$SRCROOT/app WatchKit App/Info.plist"

From app WatchKit App the app should be the name of your app, but check the exact path.

You can update the build version of all your targets without a build script. (You can also use this to update the marketing / short build version; in this case ignore changes to CFBundleVersion).

Open your project settings and set CURRENT_PROJECT_VERSION (Current Project Version) to the desired version number. In all targets make sure CURRENT_PROJECT_VERSION is empty (so that its value is inherited from the project). Then in all Info.plist files set CFBundleShortVersionString (Bundle versions string, short) and CFBundleVersion (Bundle version / build version) to $(CURRENT_PROJECT_VERSION).

Optionally, you can distinguish between the build version and the "marketing" version (this is useful if the build version is generated automatically). To do so, in your project settings, set MARKETING_VERSION (Marketing Version) to the desired version number. As before, make sure all targets inherit the value from the project. Finally, in all Info.plist files set CFBundleShortVersionString (Bundle versions string, short) to $(MARKETING_VERSION).

If you want to increment your CFBundleVersion on each build (or to have it reflect your git SHA). Use agvtool as described by dogsgod or see https://developer.apple.com/library/ios/qa/qa1827/_index.html.
