Couldn't find platform family in Info.plist CFBundleSupportedPlatforms or Mach-O LC_VERSION_MIN for phantomjs
Had the same error, in my case the problem was that I had some DSYM files among my bundle resources.
Fixed it by removing all .DSYM files form Copy Bundle Resources build phase.

I solved this issue by removing unneeded files in my project. Specifically I have a Cartfile in my project and the Carthage Folder reference so that I can easily access it.
I removed the folder reference but I kept the Cartfile in my project. I made sure that the Cartfile is not in my Copy Bundle Resources build phase. One of these 2 fixed my problem.
