### Create Jellyfin Client and Sign In

Source: https://github.com/jellyfin/jellyfin-sdk-swift/blob/main/README.md

Instantiate the JellyfinClient and authenticate a user with their username and password. This client handles authorization headers and date decoding.

```swift
let jellyfinClient = JellyfinClient(configuration: configuration)

let response = jellyfinClient.signIn(username: "jelly", password: "fin")
```

### Open WebSocket Session and Subscribe to Events

Source: https://github.com/jellyfin/jellyfin-sdk-swift/blob/main/README.md

Establishes a WebSocket connection for real-time updates. Allows subscribing to various event feeds like sessions and activity logs with optional intervals. Events are delivered as a stream.

```swift
let session = client.socket(
    supportsMediaControl: true,
    supportedCommands: [.displayMessage, .play, .pause]
).connect()

session.subscribe(.sessions)
session.subscribe(.activityLog, interval: .seconds(10))

for try await event in session.events {
    switch event {
    case .connecting:
        print("Connecting...")
    case let .connected(url):
        print("Connected to \(url)")
    case let .message(message):
        switch message {
        case let .sessionsMessage(msg):
            print("Sessions: \(msg)")
        default:
            break
        }
    }
}

session.unsubscribe(.activityLog)
session.disconnect()
```

### Update OpenAPI Specification

Source: https://github.com/jellyfin/jellyfin-sdk-swift/blob/main/README.md

### Discover Jellyfin Servers on Local Network

Source: https://github.com/jellyfin/jellyfin-sdk-swift/blob/main/README.md

Scans the local network for Jellyfin servers using UDP broadcast over IPv4. Returns discovered server details including name and URL within a specified duration.

```swift
for try await server in JellyfinClient.discover(duration: .seconds(5)) {
    print("Found server: \(server.name) at \(server.url)")
}
```

### Quick Connect Authentication Flow

Source: https://github.com/jellyfin/jellyfin-sdk-swift/blob/main/README.md

Implements the Quick Connect authorization flow. It polls for connection states and proceeds to authenticate using a received secret upon successful connection.

```swift
for try await state in client.quickConnect.connect() {
    switch state {
    case let .polling(code: code):
        print("Code: \(code)")
    case let .authenticated(secret: secret):
        try await client.signIn(quickConnectSecret: secret)
    }
}
```
