I have just taken over an umbraco project that is using U7 Grid Data Type package

https://our.umbraco.org/projects/backoffice-extensions/u7-grid-data-type

The problem I have is outputting the values inside the data type.

var steps = recipeContent.GetProperty("preparationSteps"); 

                    foreach (var row in steps)
                    {

                    }

error CS1579: foreach statement cannot operate on variables of type 'Umbraco.Core.Models.IPublishedProperty' because 'Umbraco.Core.Models.IPublishedProperty' does not contain a public definition for 'GetEnumerator'

Any ideas?
