Is it possible to send complex Arrays from iPhone to AppleWatch with watch connectivity?

I have a problem passing data from iOS to WatchOS 2.0

I want to send an ArrayList to WatchOS but my ArrayList has no type like String, Int but an Object that I generated.

    // here I fetch my Lists with Users
    var friendList: [UserProfile] = Utils().loadUsers("friendList")
    var blackList: [UserProfile] = Utils().loadUsers("blackList")
    var users: [UserProfile] = Utils().loadUsers("UsersList")

    // here I put the Lists in the Dictionary in order to send this Dictionary to Watch
    let dictionary: [String: AnyObject]=[
        "UsersList" : self.users,
        "BlackList" : self.blackList,
        "FriendList" : self.friendList
    ]

    WCSession.defaultSession().sendMessage(dictionary, replyHandler: { (data) -> Void in
        // handle the response from the device

        }) { (error) -> Void in
            print("error: \(error.localizedDescription)")
    }

In my WatchApp Class I try to get the Data but there is following error:

error: Payload contains unsupported type.

This is how I want to get the Data. If I send Bools, Integers or String this works, but not for Arrays like mine:

let userList: [UserProfile] = applicationContext["UsersList"] as! [UserProfile]
let blackList: [UserProfile] = applicationContext["BlackList"] as! [UserProfile]
let friendList: [UserProfile] = applicationContext["FriendList"] as! [UserProfile]

Hope anyone can help me with this Problem.

UserProfile objects friendList, blackList, users are not serialised yet, and cannot be directly send to Apple Watch.

You can convert them to dictionaries before sending them to the Apple Watch.
