Install

Swift Package Manager

The Swift Package Manager is a tool for managing the distribution of Swift code. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies. Since the release of Swift 5 and Xcode 11, SPM is compatible with the iOS, macOS and tvOS build systems for creating apps.

To use SwiftPM, you should use Xcode 11 to open your project. Click File -> Swift Packages -> Add Package Dependency, enter InstantSearch repo's URL.

If you're a framework author and use Swift API Client as a dependency, update your Package.swift file:

let package = Package(
    // 8.0.0 ..< 9.0.0
    dependencies: [
        .package(url: "https://github.com/algolia/algoliasearch-client-swift", from: "8.0.0")
    ],
    // ...
)

Add import AlgoliaSearchClient to your source files.

Cocoapods

CocoaPods is a dependency manager for Cocoa projects.

To install Algolia Swift Client, simply add the following line to your Podfile:

pod 'AlgoliaSearchClient', '~> 8.0'
# pod 'InstantSearchClient', '~> 6.0'` // Swift 4.2
# pod 'InstantSearchClient', '~> 5.0'` // Swift 4.1

Then, run the following command:

$ pod update

Carthage

Carthage is a simple, decentralized dependency manager for Cocoa.

  • To install InstantSearch, simply add the following line to your Cartfile:
github "algolia/algoliasearch-client-swift" ~> 8.0.0
# github "algolia/algoliasearch-client-swift" ~> 6.0.0` // Swift 4.2
# github "algolia/algoliasearch-client-swift" ~> 5.0.0` // Swift 4.1
  • Launch the following commands from the project directory (for v.8.0+)
carthage update
./Carthage/Checkouts/algoliasearch-client-swift/carthage-prebuild
carthage build

If this is your first time using Carthage in the project, you'll need to go through some additional steps as explained over at Carthage.

💡 Getting Started

Initialize the client

To start, you need to initialize the client. To do this, you need your Application ID and API Key. You can find both on your Algolia account.

let client = Client(appID: "YourApplicationID", apiKey: "YourAdminAPIKey")
let index = client.index(withName: "your_index_name")

Push data

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

struct Contact: Encodable {
  let firstname: String
  let lastname: String
  let followers: Int
  let company: String
}

let contacts: [Contact] = [
  .init(firstname: "Jimmie", lastname: "Barninger", followers: 93, company: "California Paint"),
  .init(firstname: "Warren", lastname: "Speach", followers: 42, company: "Norwalk Crmc")
]

let index = client.index(withName: "contacts")
index.saveObjects(contacts, autoGeneratingObjectID: true) { result in
  if case .success(let response) = result {
    print("Response: \(response)")
  }
}

Search

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

index.search(query: "jimmie") { result in
  switch result {
  case .failure(let error):
    print("Error: \(error)")
  case .success(let response):
    print("Response: \(response)")
  }
}

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 settings = Settings()
  .set(\.customRanking, to: [.desc("followers")])
index.setSettings(settings) { result in
  if case .failure(let error) = result {
    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):

Note: 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 settings = Settings()
  .set(\.searchableAttributes, to: ["lastname", "firstname", "company"])
index.setSettings(settings) { result in
  if case .failure(let error) = result {
    print("Error when applying settings: \(error)")
  }
}
