An Xcode build phase script to automatically run mogenerator on your xcdatamodel if it has changed

genModels.sh

# Xcode sets up its own PATH variable so we want to ensure that it includes /usr/local/bin
PATH=$PATH:/usr/local/bin

# Check that mogenerator is available
command -v mogenerator >/dev/null 2>&1 || { echo >&2 "You need mogenerator but it's not installed.  To install using homebrew use 'brew install mogenerator'. Aborting."; exit 1; }

# Change the working dir to where our models are
cd "${SRCROOT}"/Models

# Only run mogenerator if the access time for ResultsCache.xcdatamodeld is newer than our lock file
MODEL_ACCESS=$[ $(stat -f '%m' ResultsCache.xcdatamodeld) ]
LOCK_ACCESS=$[ $(stat -f '%m' mogenerator.lock) ]

if [ $MODEL_ACCESS -gt $LOCK_ACCESS ]; then

# Run mogenerator
