Estou tentando utilizarCloudKit no meu aplicativo iOS, mas quando tento criar um novo registro para umUser tipo de registro (o tipo de registro é nomeadoUsers), Recebo este erro:

<CKError 0x7fb80947ffb0: "Permission Failure" (10/2007);
server message = "CREATE operation not permitted";
uuid = 8C4C7B60-E3F4-42FC-9551-D3A76A6FF9D6;
container ID = "iCloud.com.jojodmo.Blix">

Para criar o novo registro, estou usando este código emviewDidLoad():

UserCKManager.create(
    CloudKitUser(
        email: "[email protected]", password: "password", salt: "1AF4E759B20FEC32",
        username: "jojodmo", posts: [], biography: "This is my bio",
        firstName: "John", lastName: "Doe", flags: [],
        profilePicture: UIImage(), downVotesGiven: 1, downVotesRecieved: 2,
        upVotesGiven: 3, upVotesRecieved: 4, pictureProvided: false), callback: nil)

O que cria um novoCloudKitUser:

init(email: String, password: String, salt: String, username: String, posts: [String], biography: String, firstName: String, lastName: String, flags: [String], profilePicture: UIImage, downVotesGiven: Int, downVotesRecieved: Int, upVotesGiven: Int, upVotesRecieved: Int, pictureProvided: Bool){ 
    self.ready = false
    record = CKRecord(recordType: "Users")
    self.email = email
    self.password = password
    self.salt = salt
    self.username = username
    self.posts = posts
    self.biography = biography
    self.firstName = firstName
    self.lastName = lastName
    self.flags = flags
    self.profilePicture = profilePicture
    self.downVotesGiven = downVotesGiven
    self.downVotesRecieved = downVotesRecieved
    self.upVotesGiven = upVotesGiven
    self.upVotesRecieved = upVotesRecieved
    self.pictureProvided = pictureProvided
    self.ready = true
}

E, em seguida, tenta criar um registro com ele:

class func create(user: User, callback: ((success: Bool, user: User?) -> ())?){
    let ckUser = CloudKitUser(user: user)
    //I've also tried using CKContainer.defaultContainer().privateCloudDatabase, and I get the same error
    CKContainer.defaultContainer().publicCloudDatabase.saveRecord(ckUser.record){(record, error) in
        if(error != nil){
            println("An error occurred: \(error)")
            callback?(success: false, user: nil)
        }
        else{
            println("Record saved successfully")
            callback?(success: true, user: ckUser)
        }
    }
}

Sei que não há problema em conectar-me ao banco de dados, porque já recebi um erro ao dizer que não havia contêiner com o ID que eu havia fornecido, que eu corrigi.

Estou tentando executar isso noiOS simulador (estou logado no iCloud)
