无法打开 Xcode 中的游乐场

Playground in Xcode cannot be opened

我无法创建 playground 项目,按下 cmd+option+shift+N 或单击 'Get started with a playground' 后,如下图所示,没有任何反应。没有 window 弹出窗口,没有任何消息。

谁能帮我弄清楚为什么?

好的,我终于在Console应用程序中找到了下面的登录

上面说XcodeCould not find suitable playground file template,然后我意识到我几个月前修改了代码模板,所以我打算删除它们

sudo rm -rf ~/Library/Developer/Xcode/Templates/File\ Templates/

那么 playground 就可以了!这可能是由不兼容的模板文件引起的。
