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，如果这是新测试版的一个问题，我在第二个测试版上尝试了同样的事情，我还没有打开或使用它。同样的事情。
我在Sierra 10.12.5上，因此测试版应该适用于操作系统。以下是崩溃日志的一部分：

我在Twitter上问过，似乎没有其他人有类似的问题。我就此问题提交了Radar。我正在处理几个技术资料，并且无法在Xcode测试项目中打开项目非常不方便。如果您有任何关于如何解决此问题的建议，我将不胜感激。

如果它仍然是实际的我有同样的问题并修复它从以下位置删除Xcode缓存：
rm -rf ~/Library/Caches/com.apple.dt.Xcode.sourcecontrol.Git
