Project 'Pods' - Turn on Whole Module Optimization

Question

In Xcode 9 I'm getting the following suggestion for a cocoa pods project:

What does it do? And, shall I turn it on, or it will break things up?

Answer 1

You can have this automatically enabled each time you run pods install by adding the below post_install script to the end of your Podfile.

post_install do |installer|    installer.pods_project.build_configurations.each do |config|     if config.name == 'Release'       config.build_settings['SWIFT_COMPILATION_MODE'] = 'wholemodule'     end       end end 

In older versions of Xcode you will need:

post_install do |installer|    installer.pods_project.build_configurations.each do |config|     if config.name == 'Release'       config.build_settings['SWIFT_OPTIMIZATION_LEVEL'] = '-Owholemodule'     else       config.build_settings['SWIFT_OPTIMIZATION_LEVEL'] = '-Onone'     end       end end
