Building the CocoaPods dependency project FBSDKCoreKit...
 =============================================================================
 WARNING: this project contains shell scripts, which CANNOT BE RUN on Windows
 without being translated first.
 WORKAROUND: for now, please remove your assets & plugins having shell scripts
 in their build phases, or translate them to batch scripts and call them in a
 pre-packaging script (or ignore this warning if the scripts are non-critical)
 In Xcode project: Pods.xcodeproj/project.pbxproj

error: your project contains code written in the Swift language, but the Swift compiler hasn't been ported to Windows yet.
Possible workarounds:
 - If this source file is part of a third-party dependency, look for an Objective-C/C++ only version of that dependency and use it instead.
 - If this source file is part of your project itself, rewrite it in C, C++, Objective-C or Objective-C++.
