CloudKit - “Invalid bundle ID for container”

I've just create a project in Xcode 9 beta 6 and add this code:

let privateDB = CKContainer.default().privateCloudDatabase 
let greatID = CKRecordID(recordName: "GreatPlace") 
let place = CKRecord(recordType: "Place", recordID: greatID) 
privateDB.save(place) { (record, error) in
      if error != nil { 
          let er = (error as! CKError).errorUserInfo 
          print("Error: \n") 
          print("CKErrorDescription: \(er["CKErrorDescription"]!)\n") 
          print("ContainerID: \(er["ContainerID"]!)\n")
          print("NSDebugDescription: \(er["NSDebugDescription"]!)\n")
          print("NSUnderlyingError: \(er["NSUnderlyingError"]!)\n")
          print("NSLocalizedDescription: \(er["NSLocalizedDescription"]!)\n")
          print("ServerErrorDescription: \(er["ServerErrorDescription"]!)\n")
    }
    if record != nil { 
          print("record: \(record!)") 
    }
}

and add icloud capabilities with Use default containers and when I run the code I receive this erros message:

Error:
CKErrorDescription: Error saving record <CKRecordID: 0x7fd8e9684560; recordName=GreatPlace, zoneID=_defaultZone:__defaultOwner__> to server: Invalid bundle ID for container

NSLocalizedDescription: Error saving record <CKRecordID: 0x7fd8e9684560; recordName=GreatPlace, zoneID=_defaultZone:__defaultOwner__> to server: Invalid bundle ID for container

What I am doing wrong ?
