Quickstart

Stream your first biosignal from a BLE wearable in under 5 minutes.

1. Install the SDK​

Add the binary Swift package in Xcode:

  1. File > Add Package Dependencies...
  2. Enter: https://github.com/anybio/biosdk-ios-binary.git
  3. Add the BioSDK product to your app target

See the full Installation guide for details.

2. Configure the SDK​

import BioSDK

// Initialize with your project credentials
let config = BioSDKClient.Configuration(
    environment: .auto,
    organizationKey: "org_your_key",
    projectKey: "proj_your_key"
)

let sdk = try await BioSDKClient.initialize(configuration: config)

3. Subscribe to Events​

import Combine

var cancellables = Set<AnyCancellable>()

sdk.events
    .sink { event in
        switch event {
        case .lifecycle(let lifecycle):
            switch lifecycle {
            case .discovered(let device):
                print("Found: \(device.name)")
            case .connected(let device):
                print("Connected: \(device.name)")
            case .disconnected(let device, _, _, _):
                print("Disconnected: \(device.name)")
            }

        case .sample(let deviceId, let sample):
            print("[\(deviceId)] \(sample.signalName): \(sample.data)")

        case .deviceState(let device, let connection, let stream):
            print("\(device.name): \(connection) / \(stream)")

        case .session(let sessionEvent):
            print("Session: \(sessionEvent)")

        case .notification:
            break
        }
    }
    .store(in: &cancellables)

4. Scan and Connect​

// Start scanning for BLE devices
sdk.startScan()

// When you find your device (e.g., from a UI list):
let device = sdk.discoveredDevices.first!
sdk.connect(device)

5. Start Streaming​

Once the device reaches .ready connection state:

sdk.startStreaming(deviceId: device.id)

Biosignal samples will flow through the events publisher as .sample events.

6. Stop and Disconnect​

sdk.stopStreaming(deviceId: device.id)
sdk.disconnect(device)
