当我在Project Navigator中选择任何文件或尝试编辑时，App Store中的Xcode 5崩溃了。我已经删除了应用程序的所有插件和派生数据，并且它一直在崩溃。
有谁知道如何解决这个问题以及为什么会这样？
以下是错误的第一部分。
Exception Type: EXC_CRASH (SIGABRT)

我也遇到过这个问题。要防止xCode5崩溃，请按照以下步骤操作。 Xcdoe＆gt;偏好＆gt;源控制＆gt;取消选中“启用源”控件。之后，Xcode不会崩溃.. :)
答案 1 :(得分：3)
我在使用Xcode 6.1时第一次遇到这个问题。
我刚刚克隆了项目，一旦索引过程开始，它就会崩溃。我按照上一个答案中的建议禁用了源代码管理，但它仍然崩溃。
在我的情况下，问题是目标是当时连接到我的MAC的设备，但是我没有包含在我安装在MAC上的任何配置文件中。在索引过程开始之前将目标更改为任何模拟器将为我解决问题。
答案 2 :(得分：0)
从xcode7.2升级到7.3时遇到了同样的问题。 一切都很好，除了冲突的 PLUGINs 。
尝试删除您在xcode中安装的插件，它会起作用。在我的情况下，恶魔岛插件是罪魁祸首。刚从路径 / Library / Application Support / Developer / Shared / Xcode 中删除它，一切顺利。
P.S ：确保您的mac OS与您正在安装的xcode兼容!!有时盲目地安装xcode而不升级操作系统（就像我正在做的那样;））会导致这种危险行为。祝你好运!!
