How do I disable swashbuckle swagger UI in production in ASP.NET web api2?

If you are using NET framework (any version capable of having swagger)

</appSettings>

2. If you installed swagger from nuget package already, then you have the (*\App_Start\SwaggerConfig.cs)

in there find the Register() method and add code as the following

public static void Register()
{
         var thisAssembly = typeof(SwaggerConfig).Assembly;

         // if key in config does not exist we set it to true
         // you can play to make it always false ***
         bool isSwaggerEnabled = ConfigurationManager.AppSettings["IsSwaggerEnabled"] != null ?
             bool.Parse(ConfigurationManager.AppSettings["IsSwaggerEnabled"]) : true;

         // if swagger is not enabled we don't even bother to config it,
         // therefor will be disabled, and you don't have to worry about it.
         if (!isSwaggerEnabled)
             return;

         GlobalConfiguration.Configuration
             .EnableSwagger(c =>
