swift 中的 PNDate return 无

Question

我用
PubNub.requestFullHistoryForChannel(channel , includingTimeToken: true , withCompletionBlock: { messages , channel , startDate , endDate , error in let dic = messages[0].message as Dictionary<String , String> let date = messages[0].date as PNDate! })
获取历史消息当我使用 println() 显示消息时 **date : PNDate ** is not nil

 "PNMessage (0x7fcb69d252c0): <message: {\n    text = yup;\n    type = fromUser;\n}, date: PNDate (0x7fcb69d25300) <date: 2015-02-17 12:21:31 +0000; time token: 14241756912535903>, channel: Hazem>"
