Xamarin Profiler無法從VS2015連接並運行iOS應用

Question

我正在嘗試分析iOS應用程序以診斷內存泄漏。 當我嘗試從Visual Studio運行Xamarin Profiler時，應用程序會正常編譯並部署到設備，但是在Profiler加載后，我選擇了監視它的位暫停，然后報告“對不起，嘗試運行***時出錯了*** ”。 日志輸出如下：

我正在運行Visual Studio 2015 U3的完整更新的企業版和Windows 8.1上的最新穩定Xamarin工具，以及在運行OSX 10.11.5的MacBook Pro上使用Xamarin Studio的最新穩定工具以及最新的Xamarin Profiler。 我的測試設備是運行iOS 9.3.2的iPhone 6 Plus。 該安裝程序正常運行，完全調試等，沒有問題。

任何幫助都將受到歡迎！

這是目前已知的問題。 我們確實為此提供了一個錯誤報告，但是它是內部的，因此很遺憾，我無法共享任何細節。

我建議立即在您的Mac上直接嘗試Profiler-或使用Instruments：
