In addition to the correct answer, I added this to my podfile.

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '5.0'
      end
  end
end

After upgrading to Xcode 10.2 release make sure you reboot MacOS. I had the exact same problem and reboot helped.

For XCode 10.1, select your Pods File

Select Pod

-> Go to Build Settings -> Choose your Pod -> Search "Swift" -> Navigate to "Swift Language version" -> Set to desired language version.

You have code which was compiled on the new Xcode 10.2 or the beta version which supports Swift 5. Update your Xcode to the latest version.
