Swift

Getting Started

Supported platforms

Our Swift client is supported on iOS, macOS, tvOS and watchOS, and is usable from both Swift and Objective-C.

Install

  1. Add a dependency on AlgoliaSearch-Client-Swift:
    • CocoaPods: add pod 'AlgoliaSearch-Client-Swift', '~> 4.0' to your Podfile.
    • Carthage: add github "algolia/algoliasearch-client-swift" to your Cartfile.
  2. Add import AlgoliaSearch to your source files.

Quick Start

In 30 seconds, this quick start tutorial will show you how to index and search objects.

Initialize the client

You first need to initialize the client. For that you need your Application ID and API Key. You can find both of them on your Algolia account.

let client = Client(appID: "YourApplicationID", apiKey: "YourAPIKey")

The api key that is displayed here is your ADMIN API Key, never use it in your frontend nor give it to anyone.

In your frontend, you should use the SEARCH ONLY API Key or any other key that has search rights only

Push data

Without any prior configuration, you can start indexing 500 contacts in the contacts index using the following code:

// Load content file
let jsonURL = Bundle.main.url(forResource: "contacts", withExtension: "json")
let jsonData = try! Data(contentsOf: jsonURL!)
let dict = try! JSONSerialization.jsonObject(with: jsonData!)

// Load all objects in the JSON file into an index named "contacts".
let index = client.index(withName: "contacts")
index.addObjects(dict["objects"])

You can now search for contacts using firstname, lastname, company, etc. (even with typos):

// search by firstname
index.search(Query(query: "jimmie"), completionHandler: { (content, error) -> Void in
	if error == nil {
		print("Result: \(content)")
	}
})
// search a firstname with typo
index.search(Query(query: "jimie"), completionHandler: { (content, error) -> Void in
	if error == nil {
		print("Result: \(content)")
	}
})
// search for a company
index.search(Query(query: "california paint"), completionHandler: { (content, error) -> Void in
	if error == nil {
		print("Result: \(content)")
	}
})
// search for a firstname & company
index.search(Query(query: "jimmie paint"), completionHandler: { (content, error) -> Void in
	if error == nil {
		print("Result: \(content)")
	}
})

Configure

Settings can be customized to tune the search behavior. For example, you can add a custom sort by number of followers to the already great built-in relevance:

let customRanking = ["desc(followers)"]
let settings = ["customRanking": customRanking]
index.setSettings(settings, completionHandler: { (content, error) -> Void in
	if error != nil {
		print("Error when applying settings: \(error!)")
	}
})

You can also configure the list of attributes you want to index by order of importance (first = most important):

Since the engine is designed to suggest results as you type, you’ll generally search by prefix. In this case the order of attributes is very important to decide which hit is the best:

let customRanking = ["lastname", "firstname", "company", "email", "city", "address"]
let settings = ["searchableAttributes": customRanking]
index.setSettings(settings, completionHandler: { (content, error) -> Void in
	if error != nil {
		print("Error when applying settings: \(error!)")
	}
})
