因此，今天在打开Xcode(版本10.1(10B61))时，它安装了一些其他软件包(不幸的是，我不知道是什么).然后，在打开任何东西(现有项目，创建新项目，创建游乐场)时，它崩溃并显示以下错误.

So today while opening Xcode (Version 10.1 (10B61)) it installed some additional packages (unfortunately I don't know what). Then when it came to opening anything (existing project, creating a new project, creating playground) it crashed with error as posted below.

我尝试重新安装Xcode，但是发生了相同的错误. 我正在使用MacOS Mojave(版本10.14(18A314k))

I tried reinstalling Xcode, but the same error occurred. I'm using MacOS Mojave (version 10.14 (18A314k))

最后是一个错误:

推荐答案

我遇到了同样的问题，在我将操作系统更新到最新版本后，它在Xcode App启动时崩溃了.

I ran into the same issue, It's crashing on launch of Xcode App after that I updated the OS to the latest version.

由于以下问题

+[NSColor detailAccentColor]: unrecognized selector sent to class 0x7fff9fa73e28
