atacan/ElevenLabs

Requirements

• Swift 5.9+
• macOS 13+, iOS 16+, tvOS 16+, watchOS 9+

Installation

Add to your Package.swift:

dependencies: [
    .package(url: "https://github.com/atacan/ElevenLabs", branch: "main"),
],
targets: [
    .target(
        name: "YourTarget",
        dependencies: [
            .product(name: "ElevenLabs", package: "ElevenLabs"),
        ]
    ),
]

Use ElevenLabsTypes instead if you only need the types (e.g. for a server-side target that shares models).

Products

| Product | Description | |---|---| | ElevenLabsTypes | Generated request/response types and the AuthenticationMiddleware | | ElevenLabs | Generated HTTP client + createClient(apiKey:) factory function |

Usage

Creating a client

import ElevenLabs

let client = createClient(apiKey: "your-api-key")

createClient points at https://api.elevenlabs.io and attaches an AuthenticationMiddleware that injects the xi-api-key header on every request.

Text to Speech

import ElevenLabs
import ElevenLabsTypes
import OpenAPIRuntime

let response = try await client.text_to_speech_full(
    Operations.text_to_speech_full.Input(
        path: .init(voice_id: "YVyp28LAMQfmx8iIH88U"),
        body: .json(
            Components.Schemas.Body_text_to_speech_full(
                text: "Hello, world!",
                model_id: "eleven_multilingual_v2"
            )
        )
    )
)

let audioBody: HTTPBody = try response.ok.body.audio_mpeg
let audioData: Data = try await Data(collecting: audioBody, upTo: 10 * 1024 * 1024)

Other text-to-speech operations:

| Operation | Description | |---|---| | text_to_speech_full | Full audio file, audio/mpeg response | | text_to_speech_full_with_timestamps | Full audio + character-level timing JSON | | text_to_speech_stream | Streaming audio | | text_to_speech_stream_with_timestamps | Streaming audio + timing JSON |

Speech to Text

import ElevenLabs
import ElevenLabsTypes
import OpenAPIRuntime

let audioData = try Data(contentsOf: audioFileURL)

let response = try await client.speech_to_text(
    Operations.speech_to_text.Input(
        query: .init(enable_logging: true),
        body: .multipartForm([
            .model_id(.init(payload: .init(body: HTTPBody("scribe_v1")))),
            .file(.init(payload: .init(body: HTTPBody(audioData)), filename: "audio.wav")),
        ])
    )
)

let result = try response.ok.body.json.value1  // SpeechToTextChunkResponseModel?
print(result?.text ?? "")

The multipart body supports additional parts such as .language_code, .diarize, .timestamps_granularity, etc. — all cases of Components.Schemas.Body_Speech_to_Text_v1_speech_to_text_post.

Accessing structured output

Responses follow a consistent pattern: call .ok (throws if the status was not 200), then .body, then the content-type accessor:

// JSON response
let payload = try response.ok.body.json

// Binary response
let audioBody = try response.ok.body.audio_mpeg

Enabled API tags

The generator configs filter to a subset of the full ElevenLabs API. Currently enabled tags:

• speech-to-text
• text-to-speech

To enable additional tags, edit openapi-generator-config-types.yaml and openapi-generator-config-client.yaml, then run make regenerate.

Development

Regenerating from OpenAPI spec

The Swift sources under Sources/*/GeneratedSources/ are generated — do not edit them by hand.

To regenerate after updating openapi.json or the generator configs:

make regenerate

This runs swift-package-generator-based-on-openapi via uvx, which rebuilds the package scaffolding and re-runs the generator.

To run only the Swift OpenAPI Generator step (without rebuilding scaffolding):

make generate

Other make targets

make build          Build the Swift package
make test           Run tests
make format         Run swift-format on Sources and Tests
make test-on-linux  Run tests inside a Docker container (swift:latest)
make merge-main     Merge current branch into main and push

Running tests

Tests call the live ElevenLabs API. Provide your key in a .env file in the repository root:

ELEVENLABS_API_KEY=sk-...

Then:

swift test
# or
make test
