“Too many symbol files” warning when submitting app

Question

I submitted my app to the app store and received the following warning (not error):

Too many symbol files - These symbols have no corresponding slice in

Answer 1

Let's say you are targeting iOS 11 but your cocoapods frameworks have minimum deployment target less that iOS 11, then add this at the end of your podfile:

post_install do |installer| 
    installer.pods_project.targets.each do |target|
        target.build_configurations.each do |config| 
            config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '11.0'
        end
    end 
end

"Too many symbol files" warning is telling you that your project has more restrictive constraints than the cocopods frameworks.
