RxSwift.Resources are being used to detect memory leaks during pre release tests.

The problem:

When trying to use RxSwift.Resources the following error occurs:

Use of unresolved identifier 'Resources'

The solution:

RxSwift.Resources are compiled conditionally and only when the "TRACE_RESOURCES" flag is present.

To include RxSwift.Resources for debug builds, update Podfile with the following code:

post_install do |installer|
   installer.pods_project.targets.each do |target|
      if target.name == 'RxSwift'
         target.build_configurations.each do |config|
            if config.name == 'Debug' 
               config.build_settings['OTHER_SWIFT_FLAGS'] ||= ['-D', 'TRACE_RESOURCES']
            end
         end
      end
   end
end
