Setting the Returned Product Attributes in Recommendations in Swift SDK

Dynamic Yield provides a default structure for product attributes returned in recommendation campaign responses. You can fine-tune these product attributes to match your business needs as described in this article. Note that when you use the chooseVariation function , you can override this default by creating a dedicated recsProductData object.

The default product attribute structure

The following is the default product structure (based on the Dynamic Yield product feed structure):

  public class DefaultRecsProductData: RecsProductData {
        let productType: ProductType?
        let groupId: String?
        let name: String?
        let url: String?
        let price: Float?
        let inStock: Bool?
        let imageUrl: String?
        let categories: [String?]?
        var keywords: [String?]?
        var extra: [String: Any?] = [:]
    }

Changing the default using Swift SDK

To add more fields to the product structure:

1. Create a new class that inherits from RecsProductData.

    public class CustomRecsProductData: RecsProductData {
        var shortColor: String = "yellow"
        var tShirtNumber: Int = 8
        var initials: String = "A.N"
    }

2. Set this class as the new default product data structure by calling setDefaultProductDataType().

  DYSdk.shared().setDefaultProductDataType(defaultRecsProductData: CustomRecsProductData.self)

3. After calling setDefaultProductDataType(), whenever chooseVariations is called for recommendations campaigns, the return value includes the fields you added to the new class. The product data will include the values in either a dedicated attribute (to the listed above attribute - product type, price, keywords, etc.), any additional attribute and it's value will be found inside the extra map.
