I changed Base SDK from 10.9 to 10.10 in my app and it solved the problem. 我在应用程序中将Base SDK从10.9更改为10.10，它解决了该问题。 As I see crash occurs only on 10.10.3 and higher system version. 如我所见，崩溃仅在10.10.3和更高版本的系统上发生。 If you want to crash TextEdit just change Base SDK to 10.9 or open TextEdit 1.9 or earlier version. 如果要使TextEdit崩溃，只需将Base SDK更改为10.9或打开TextEdit 1.9或更早版本。 Also someone already wrote radar http://openradar.appspot.com/20991953 还有人已经写过雷达http://openradar.appspot.com/20991953
