Retrieve the online status of a user

You can check if a user in the Sendbird application is currently connected to the Sendbird server. For group channels only, you can check whether each member is currently connected to the server.

var queryParam = ApplicationUserListQueryParams()
queryParam.userIdsFilter = ["Young"]
let query = SendbirdChat.createApplicationUserListQuery(params: queryParam)
query.loadNextPage { users, error in
    guard let young = users?.first, error == nil else {
        return
    }
    
    if young.connectionStatus == .online {
        // Young is online now
        // Acceptable values for User.connectionStatus are NON_AVAILABLE, ONLINE, and OFFLINE
    }
})

In a group channel, you can check the current connection status of each member. To do so, you need to first call the refresh(completionHandler:) method to update the channel with the latest information, then call members to retrieve a list of channel members.

When the members property returns a list of all members, you can call connectionStatus for each member object in the members property to check the corresponding member's current online status. Acceptable values of the connectionStatus property are offline and online.

Note: If your client app needs to keep track of the connection status of users in real time, we recommend that you periodically call the loadNextPage(completionHandler:) method of a ApplicationUserListQuery instance after specifying its userIdsFilter filter, perhaps in intervals of one minute or more.
