我今天下载了Xcode 9 Beta 3。我试图创建一个新项目。新项目模板短暂出现，然后应用程序崩溃。我很好奇这是否是新测试版的问题，我在第二个测试版上尝试了同样的事情，但我还没有打开或使用过。同样的事情。
我使用的是Sierra 10.12.5，因此测试版应该可以在操作系统上运行。以下是崩溃日志的一部分：

我在Twitter上询问了周围，似乎没有其他人遇到类似的问题。我就这个问题提交了雷达。我正在研究几份技术材料，无法在 Xcode 测试版中打开一个项目非常不方便。我将不胜感激有关如何解决此问题的任何建议。
如果它仍然是实际的，我遇到了同样的问题并修复了它，从以下位置删除 Xcode 缓存：
rm -rf ~/Library/Caches/com.apple.dt.Xcode.sourcecontrol.Git
