Xcode 11 Beta 4 Carthage workaround

carthage_workaround.rb

#!/usr/bin/env ruby

require 'find'
require 'xcodeproj'

Find.find("Carthage/Checkouts/.") do |f| 
  if f.end_with?(".xcodeproj")
    project = Xcodeproj::Project.open(f)
    project.targets.each do |target|
      target.build_configurations.each do |config|
        config.build_settings['LD_VERIFY_BITCODE'] ||= 'NO'
      end
    end
    project.save
  end
end

The workflow where I'm at is carthage update --platform ios --cache-builds --use-ssh --new-resolver which will fail with Xcode 11 beta 4. However if you run this ruby script and then do carthage build --platform iOS carthage will build your dependencies and link them fine.

There is a simpler solution, create a file like carthage_workaround.xcconfig put LD_VERIFY_BITCODE=NO in it, then just prepend your normal carthage call with XCODE_XCCONFIG_FILE=/absolute/path/to/carthage_workaround.xcconfig carthage update… and it will build.
