bitcode bundle could not be generated because iOS Charts
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' endend
Please check this SO thread and see if adding the -fembed-bitcode flag in build settings works for you.
