Xcode 11 stuck on archiving

This could help (I was having an issue with SwiftSoup, another CocoaPod). I was experiencing inexplicable hangs while trying to get Xcode 11 to archive my app (even at the command line). This is not meant to be a permanent fix, but rather a temporary workaround (in other words, we shouldn't have to do this to get a problematic library to build)!

Add this to the bottom of your Podfile and re-run pod install.

post_install do |installer|
  installer.pods_project.targets.each do |target|
    next unless target.name == '<NAME OF POD>'
    target.build_configurations.each do |config|
      next unless config.name.start_with?('Release')
      config.build_settings['SWIFT_OPTIMIZATION_LEVEL'] = '-Onone'
    end
  end
end

Then try to archive your project. If that doesn't work… perhaps try messing around with other compiler optimization settings?

I have found a clean and quick solution in the meantime, click "Pods" in the project navigator, then in targets (picture) set SwiftSoup,

In Swift compiler set both -Onone. Now try to archive.
