Cocoa pods TRACE_RESOURCES setup

[sergdort]

Hi, guys
Sorry if its not related to Rx, but could you please describe how should I set up my podfile in order to be able to see resources in the debug mode

Because now I do this manualy

Hi @sergdort ,

I believe you need a post install hook.

More info here

... and you need to set these Swift flags (I believe it is called OTHER_SWIFT_FLAGS in configuration).

Hi, @kzaher
Thanks, I did this with example of this post http://marginalfutility.net/2015/10/11/swift-compiler-flags/

If somebody interested this is my post install hook, I also did what you said with the app target, in order do use #if macro

   #if TRACE_RESOURCES
....
   #endif

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

Thanks @sergdort and @kzaher, that post_install hook did the trick! I only needed to add the post_install hook in order to access RxSwift.resourceCount. Adding the compiler flag (using whatever name) just lets you conditionally execute whatever code you write in the #if #endif block. Another way to do this is to set an environment variable in the scheme...

...and then conditionally check it using NSProcessInfo:

if NSProcessInfo.processInfo().environment["TRACE_RESOURCES"] != nil {
  print(RxSwift.resourceCount)
}

That way you can just check/uncheck a box when you want to enable or disable certain code. 😀

we can use macro now.

   #if TRACE_RESOURCES
....
   #endif
