Set the latest version as default value in the select dropdown of swagger ui

Question

I am using swagger Swashbuckle.AspNetCore latest version with .DotNetCore 2.1 api project which works fine.

Is there a way to set the default selected value with the latest version. Now, I am using for loop to get the last value and set it,

for (var i = provider.ApiVersionDescriptions.Count - 1; i >= 0; i--)
{
    var description = provider.ApiVersionDescriptions[i];
    options.SwaggerEndpoint($"/swagger/{description.GroupName}/swagger.json", description.GroupName);
}

I'm not sure if there is a better way but you could use this:

foreach ( var description in provider.ApiVersionDescriptions.OrderByDescending(x=>x.ApiVersion.MajorVersion.GetValueOrDefault()) )
{
    options.SwaggerEndpoint($"/swagger/{description.GroupName}/swagger.json", description.GroupName);
} 

Obviously you would need to add another OrderBy if you had something more than just MajorVersion changes. you could write your own OrderBy Extension if you wanted.
