bitcode bundle could not be generated because iOS Charts

Please check this SO thread and see if adding the -fembed-bitcode flag in build settings works for you.

iOS library to BitCode

I found one possible cause is if you are using CocoaPods and the dependencies are not being compiled using bitcode.

I added this to my Podfile to fix it.

post_install do |installer|
  installer.pods_project.build_configurations.each do |config|
    config.build_settings['BITCODE_GENERATION_MODE'] = 'bitcode'
    config.build_settings['ENABLE_BITCODE'] = 'YES'
  end
end

Please try to change Enable Bitcode to No in Build Settings.
