Install the iOS API client


  • Add a dependency on AlgoliaSearch-Client-Swift:
    • CocoaPods: add pod 'AlgoliaSearch-Client-Swift' to your Podfile for Swift 4
    • CocoaPods: add pod 'AlgoliaSearch-Client-Swift', '~> 4.0' to your Podfile for Swift 3
    • Carthage: add github "algolia/algoliasearch-client-swift" to your Cartfile
  • Add import AlgoliaSearch to your source files

Supported platforms

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

Language-specific notes

You can browse the automatically generated reference documentation. (See also the offline-enabled version.)


If you were using version 2.x of our Swift client, read the migration guide to version 3.x.

Init Index

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

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

You need to replace your_index_name by the name of the index you want to use. If you want to target an existing index you can find the name from the dashboard. If the index does not exist you can choose any name and it will be created when you perform an add objects or a set settings operation.

If an api key is displayed in the previous snippet it is your ADMIN API Key. To maintain security, never use your ADMIN API Key on your frontend or share it with anyone. In your frontend, use the SEARCH ONLY API Key or any other key that has search only rights.

If you are building a native app on mobile, be sure to not include the search API key directly in the source code. You should instead consider fetching the key from your servers during the app’s startup.
