#
# This script is meant to be run as a Run Script in the "Build Phases" section
# of your Xcode project. It sends debug symbols to symbolicate stacktraces,
# sends build events to track versions, and onboards apps for Crashlytics.
#
# This script calls upload-symbols twice:
#
# 1) First it calls upload-symbols synchronously in "validation" mode. If the
#    script finds issues with the build environment, it will report errors to Xcode.
#    In validation mode it exits before doing any time consuming work.
#
# 2) Then it calls upload-symbols in the background to actually send the build
#    event and upload symbols. It does this in the background so that it doesn't
#    slow down your builds. If an error happens here, you won't see it in Xcode.
#
# You can find the output for the background execution in Console.app, by
# searching for "upload-symbols".
#
# If you want verbose output, you can pass the --debug flag to this script
#

#  Figure out where we're being called from
DIR=$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )

#  Build up the arguments list, passing through any flags added, and quoting
#  every argument in case there are spaces in any of the paths.
