swift 致命错误:Double值无法转换为Int,因为它是无限或NaN

let time = TimeInterval(asset.duration.seconds)
                    if (time.isNaN || time.isInfinite){
                        print("无效文件  time.recordDuration.isNaN ||  time.recordDuration.isInfinite    ssssssss")
                        self.isInvalid = true
                    }
