# KBChatMQ SDK — iOS (Swift)

Copy `KbChatMqClient.swift` vào target (Swift 5.5+ / async-await).

## Ví dụ

```swift
let hub = KbChatMqClient(baseUrl: ProcessInfo.processInfo.environment["KBCHATMQ_HUB_URL"]!)
let r = try await hub.loginWithPassword(userId: "u1", password: secret)
if !r.ok { /* lỗi */ }
```

Dùng Keychain lưu token / khóa phòng chat. Xem `/sdk/SECURITY.md`.
