# Swift client library

#### Use InfluxDB 3 clients to query

InfluxDB 3 supports [compatibility endpoints for *writing data*](/influxdb3/core/write-data/compatibility-apis/) using InfluxDB v2 and v1 tools. However, the `/api/v2/query` API endpoint and associated tooling, such as InfluxDB v2 client libraries and the `influx` CLI, *can’t query* data stored in InfluxDB 3 Core.

[InfluxDB 3 client libraries](/influxdb3/core/reference/client-libraries/v3/) are available that integrate with your code to write and query data stored in InfluxDB 3 Core.

[**Compare tools you can use**](/influxdb3/core/get-started/#tools-to-use) to interact with InfluxDB 3 Core.

Swift is a programming language created by Apple for building applications across multiple Apple platforms.

The documentation for this client library is available on GitHub.
