我无法构建我的xamarin ios项目。早上好，很好。但现在，当我试图运行或构建我的项目时，没有任何事情发生。我没有改变任何事情。我在输出日志中找到了这个：
1>------ Build started: Project: AlarmButton.Touch, Configuration: Debug iPhone ------
1> Generated session id: f301fb763b459ef8426c2556b278a6cf
1> Generated build app name: AlarmButtonTouch

1>C:\Program Files (x86)\MSBuild\Xamarin\iOS\Xamarin.iOS.Common.targets(996,3): error :
========== Build: 0 succeeded, 1 failed, 1 up-to-date, 0 skipped ==========
修改 如果我使用iPhoneSimulator，但它仍然无法在真正的iPhone上工作，它可以正常工作
更新 有详细的日志：
