How to use iOS SDK SWGCustomSettings to set Custom Values

Thanks for the reply. Allow me rephrase it.
My question was how to use this sdk API to set user customer setting like in this thread:

here the setting variable must be in the format of SWGCustomSettings.

 userAPI.setCustomSettingsWithCompletionBlock(settings) { (success:SWGSuccess!, error:NSError!) -> Void in
            
 }

Problem was no way to set values into it and no tutorial about this customer setting.
Thanks for your time.
