Based on Stef Heyenrath's answer.

Attribute to mark properties to exclude from the Swagger documentation.

[AttributeUsage(AttributeTargets.Property)]
public class SwaggerExcludeAttribute : Attribute
{
}

The filter to exclude the properties from the Swagger documentation.

public class SwaggerExcludeSchemaFilter : ISchemaFilter
{
    public void Apply(Schema schema, SchemaFilterContext context)
    {
        if (schema?.Properties == null)
        {
            return;
        }

        var excludedProperties = 
            context.SystemType.GetProperties().Where(
                t => t.GetCustomAttribute() != null);

        foreach (var excludedProperty in excludedProperties)
        {
            var propertyToRemove =
                schema.Properties.Keys.SingleOrDefault(
                    x => x.ToLower() == excludedProperty.Name.ToLower());

            if (propertyToRemove != null)
            {
                schema.Properties.Remove(propertyToRemove);
            }
        }
    }
}

The schema.Properties.Keys are camelCase, while the properties themselves are PascalCase. Tweaked the method to convert both to lower case and compare to see what should be excluded.
