Retrieve user information using the UserRepository to display profiles, user cards, and social metadata. User objects contain core identity information and provide real-time updates when user data changes.
Live Objects: User data is returned as Live Objects that automatically update when the underlying data changes, keeping your UI synchronized.

​
Get Single User

Retrieve a specific user by their unique ID: 
var token: AmityNotificationToken?

func observeUser() {
    let liveObject = userRepository.getUser("<user-id>")
    token = liveObject.observe { liveObject, error in
        // Handle live object notification
        guard let user = liveObject.object else {
            print("Error: \(String(describing: error))")
            return
        }
        print("User ID: \(user.userId), Display Name: \(user.displayName ?? "Unknown")")
    }
}

​
Get Multiple Users

Retrieve multiple users efficiently using batch operations: 
// Get multiple users by IDs
let userIds = ["user_1", "user_2", "user_3"]

userRepository.getUsers(userIds: userIds) { result in
    switch result {
    case .success(let users):
        users.forEach { user in
            print("\(user.userId): \(user.displayName ?? "Unknown")")
        }
    case .failure(let error):
        print("Error: \(error.localizedDescription)")
    }
}

// Get all users with pagination
let liveCollection = userRepository.getUsers()

liveCollection.observe { [weak self] (collection, error) in
    guard let users = collection.object else { return }
    
    print("Loaded \(users.count) users")
    self?.displayUserList(users)
}

// Load next page
if liveCollection.hasNext {
    liveCollection.nextPage()
}
