Constructor.io Swift Client

An iOS Client for Constructor.io. Constructor.io provides search as a service that optimizes results using artificial intelligence (including natural language processing, re-ranking to optimize for conversions, and user personalization).

Documentation

Full API documentation is available on Github Pages

1. Import

1.a Import using CocoaPods

First make sure you have CocoaPods installed. Then create an empty text file in your project’s root directory called ‘Podfile’. Add the following lines to the file:

target ‘YOUR_TARGET_NAME’ do
   pod ‘ConstructorAutocomplete'
end

Open the terminal (make sure you’re located in the project root) and type

pod install

1.b Import using Carthage

First, make sure you have Carthage installed. Then create an empty text file called ‘Cartfile’ in your project root directory. Now, add the following lines:

github "Constructor-io/constructorio-client-swift"

Open the terminal (make sure you’re located in the project root) and type

carthage update

Drag the ConstructorIO.framework from Carthage/Build/iOS into your project and link it with your application target. Also, make sure to copy the framework by adding a new Copy Files phase.

2. Retrieve an API key

You can find this in your Constructor.io dashboard. Contact sales if you'd like to sign up, or support if you believe your company already has an account.

3. Create a Client Instance

Make sure to import the ConstructorAutocomplete module at the top of your source file and then write the following

// Create the client config
let config = ConstructorIOConfig(
   apiKey: "YOUR API KEY",
   baseURL: "ac.cnstrc.com", // default
   resultCount: AutocompleteResultCount(numResultsForSection: ["Search Suggestions" : 3, "Products" : 0])
)

// Create the client instance
let constructorIO = ConstructorIO(config: config)

// Set the user ID (for a logged in user) used for cross device personalization
constructorIO.userID = "abcdefghijk-123"

4. Request Autocomplete Results

let query = CIOAutocompleteQuery(query: "apple", numResultsForSection: ["Products": 6, "Search Suggestions": 8])

constructorIO.autocomplete(forQuery: query) { (response) in
  let data = response.data!
  let error = response.error!
  // ...
}

5. Request Search Results

let filters = CIOQueryFilters(groupFilter: "Bread", facetFilters: [
  (key: "Nutrition", value: "Organic"),
  (key: "Nutrition", value: "Natural"),
  (key: "Nutrition", value: "Whole-grain")
])
let query = CIOSearchQuery(query: "Dave's Bread", page: 5, filters: filters)

// Specify the sort order in which groups are returned
let groupsSortOption = CIOGroupsSortOption(sortBy: CIOGroupsSortBy.value, sortOrder: CIOGroupsSortOrder.ascending)

constructorIO.search(forQuery: query, filters: filters, groupsSortOption: groupsSortOption) { (response) in
  let data = response.data!
  let error = response.error!
  // ...
}

6. Request Browse Results

let query = CIOBrowseQuery(filterName: "potato", filterValue: "russet")

// Specify the sort order in which groups are returned
let groupsSortOption = CIOGroupsSortOption(sortBy: CIOGroupsSortBy.value, sortOrder: CIOGroupsSortOrder.ascending)

constructorIO.browse(forQuery: query, groupsSortOption: groupsSortOption) { (response) in
  let data = response.data!
  let error = response.error!
  // ...
}

7. Request Recommendation Results

let query = CIORecommendationsQuery(podId: "pdp_best_sellers", filters: filters)

constructorIO.recommendations(forQuery: query) { (response) in
  let data = response.data!
  let error = response.error!
  // ...
}

With an item id for the alternative/complementary items recommendations strategy

let itemId = "P18232"
let query = CIORecommendationsQuery(podId: "pdp_complementary_items", itemId: itemId)

constructorIO.recommendations(forQuery: query) { (response) in
  let data = response.data!
  let error = response.error!
  // ...
}

With filters for the filtered item recommendations strategy

let filters = CIOQueryFilters(groupFilter: "cat_1234", facetFilters: [
  (key: "Nutrition", value: "Organic"),
  (key: "Nutrition", value: "Natural"),
  (key: "Brand", value: "Kroger")
])
let query = CIORecommendationsQuery(podId: "pdp_filtered_items", filters: filters)

constructorIO.recommendations(forQuery: query) { (response) in
  let data = response.data!
  let error = response.error!
  // ...
}

8. Request Quiz Next Question

let query = CIOQuizQuery(quizId: "quiz-1", answers: [["1"], ["2"]])

constructorIO.getQuizNextQuestion(forQuery: query) { (response) in
  let data = response.data!
  let error = response.error!
  // ...
}

9. Request Quiz Results

let query = CIOQuizQuery(quizId: "quiz-1", answers: [["1"], ["2"]])

constructorIO.getQuizResults(forQuery: query) { (response) in
  let data = response.data!
  let error = response.error!
  // ...
}

10. Instrument Behavioral Events

The iOS Client sends behavioral events to Constructor.io in order to continuously learn and improve results for future Autosuggest and Search requests. The Client only sends events in response to being called by the consuming app or in response to user interaction . For example, if the consuming app never calls the SDK code, no events will be sent. Besides the explicitly passed in event parameters, all user events contain a GUID based user ID that the client sets to identify the user as well as a session ID.

Three types of these events exist:

General Events are sent as needed when an instance of the Client is created or initialized
Autocomplete Events measure user interaction with autocomplete results
Search Events measure user interaction with search results
Browse Events measure user interaction with browse results
Recommendation Events measure user interaction with recommendations
Conversion Events measure user events like add to cart or purchase

Autocomplete Events

// Track when the user focuses into the search bar
constructorIO.trackInputFocus(searchTerm: "")

// Track when the user selects an autocomplete suggestion

// Track when the user submits a search (either by selecting a suggestion or not selecting a suggestion)

Conversion Events

// Track when an item converts (a.k.a. is added to cart) regardless of the user journey that led to adding to cart
constructorIO.trackConversion(itemName: "Fashionable Toothpicks", customerID: "1234567-AB", variationID: "1234567-AB-47398", revenue: 12.99, searchTerm: "tooth", conversionType: "add_to_cart")

// Track when items are purchased
constructorIO.trackPurchase(customerIDs: ["123-AB", "456-CD"], revenue: 34.49, orderID: "343-315")

  CIOItem(customerID: "custID2", variationID: "varID2", quantity: 3)
