# Daily Client SDK for iOS

> Build real-time video and audio calling into your native iOS applications.

The Daily Client SDK for iOS is a native Swift library built on WebRTC. It handles media negotiation, network traversal, and participant management so you can focus on building your UI.

## Hello, world

Add the SDK via Swift Package Manager (`https://github.com/daily-co/daily-client-ios.git`), then join a call:

```swift theme={null}
import Daily

class CallViewController: UIViewController {
    let call: CallClient = .init()
    var videoViews: [ParticipantId: VideoView] = [:]

    override func viewDidLoad() {
        super.viewDidLoad()
        call.delegate = self

        call.join(url: URL(string: "https://your-domain.daily.co/room-name")!) { result in
            switch result {
            case .success: print("Joined!")
            case .failure(let error): print("Error: \(error)")
            }
        }
    }

    @IBAction func didTapTurnOffCamera(_ sender: UIButton) {
        call.setInputEnabled(.camera, false)
    }
}

extension CallViewController: CallClientDelegate {
    func callClient(_ callClient: CallClient, participantJoined participant: Participant) {
        guard !participant.info.isLocal else { return }
        let videoView = VideoView()
        videoViews[participant.id] = videoView
        addVideoViewToMyUI(view: videoView)
        videoView.track = participant.media?.camera.track
    }

    func callClient(_ callClient: CallClient, participantUpdated participant: Participant) {
        videoViews[participant.id]?.track = participant.media?.camera.track
    }

    func callClient(_ callClient: CallClient, participantLeft participant: Participant, withReason reason: ParticipantLeftReason) {
        videoViews.removeValue(forKey: participant.id)
    }
}
```

## API structure

The SDK is organized around the tasks involved in building a call. For each task you get properties/methods to **update** state, properties to **get** current state, and **delegate callbacks** via `CallClientDelegate` to react to changes.
