iOS (Swift) event tracking SDK

The RudderStack iOS (Swift) SDK enables you to track and send event data from your iOS, macOS, tvOS, and watchOS applications to any destination supported by RudderStack. Popular destinations include data warehouses like BigQuery, Redshift, and Snowflake; product analytics tools like Amplitude and Mixpanel; customer engagement platforms likeIterable, Braze, and Customer.io; ad platforms like Google Ads, Meta, and TikTok Ads; and mobile attribution tools like AppsFlyer and Adjust.Unlike traditional Android analytics SDKs that lock your event data into a single platform, RudderStack's Swift SDK acts as a single source of truth for mobile event tracking. Instrument once, then route the same events to every downstream destination in your stack.With the RudderStack iOS (Swift) SDK, you can configure your RudderStack client based on different parameters, such as the number of events in a batch request, the minimum waiting time to flush events to the server, and whether the SDK will automatically capture application lifecycle events. The SDK also supports session tracking, device ID collection, and Gzip compression for network requests.

Swift is a modern, type-safe programming language developed by Apple and the standard for building applications across Apple platforms. The RudderStack iOS (Swift) SDK is built natively for Swift, leveraging async-await and structured concurrency for non-blocking operations. It includes a dynamic plugin architecture, multi-instance support, and its platform coverage includes macOS alongside iOS, tvOS, and watchOS.

It uses direct initialization for a simple setup, and it provides type-safe direct property access to anonymousId, userId, traits, and sessionId. It also supports creating multiple isolated analytics instances with independent state, storage, and configuration - particularly useful for multi-tenant applications or tracking different data streams.
