That plugin has a dependent named cordova-plugin-add-swift-support, which relies on Cordova hooks scripts to make it work. Our build system does not allow hooks scripts, which means that the dependent plugin will not build properly with our build system. That is why you see all those build errors for the .swift file that is part of the other plugin. See this plugin.xml file for the list of problem hooks scripts > https://github.com/akofman/cordova-plugin-add-swift-support/blob/master/plugin.xml <
You'll have to build your app using Cordova CLI, I don't think PhoneGap Build allows for hooks scripts, either. They represent a security threat, which is one of the reasons we do not allow them.
If you want to convert your project to CLI, see these instructions > https://software.intel.com/en-us/forums/intel-xdk/topic/685326#comment-1885369 < and try using this script > https://github.com/xmnboy/xdk-to-cli < to help convert your project to something you can build with Cordova CLI.
