# Implements logic to build https://github.com/AzureAD/azure-activedirectory-library-for-objc and produce required lib
# Usage: place this script to azure-activedirectory-library-for-ios repo root and run

# Read technical aspects of creating framework targeting both simulator and device here: http://stackoverflow.com/a/31126203
# 1. Build iOS framework for device. Codesigning is required by Xcode, "iPhone Developer" identity is enough.
# 2. Build iOS framework for simulator.
# 3. Use lipo to produce universal iOS framework from previous two. At this point the codesigning identity of 1 step is lost: universal framework binary "is not signed at all" but that is fine since "Consumer does not care".
