xamarin mvvmcross ios Navigation错误

[Pig08]

CrossDemo.iOS[14038:249836] [TRACE] (MvvmCross.Logging.MvxLog) iOSNavigation
CrossDemo.iOS[14038:249836] [TRACE] (MvxForms) Showing of native host View in Forms is not supported.


xamarin使用mvvmcross 6.0版本，在绑定command后使用navigatioe切换页面报错如上错误

public IMvxAsyncCommand LoginCommand => _loginCommand = _loginCommand ?? new MvxAsyncCommand(async () =>
{
await _navigationService.Navigate<TestViewModel>();
});
