watchOS 6调用LCInstallation失败

watchOS 6 可以成为独立的推送目标设备，服务端啥时候能支持？

通过LCApplication.default.currentInstallation.save

https://mwqo3xyv.api.lncld.net/1.1/batch/save

\"deviceType\":\"watchos\"

------ BEGIN LeanCloud HTTP Response
task: 2
code: 400
error: Response status code was unacceptable: 400.
data: {
"code": 1,
"error": "Invalid deviceType."
}
------ END

会在watchOS 6正式发布时支持么
