Code folding was disabled in Xcode 9 beta 1, which is working now, in Xcode 9 Beta5 according to beta release note: Resolved in Xcode 9 beta 5 – IDE

代码折叠在 Xcode 9 beta 1 中被禁用，它现在正在运行，在 Xcode 9 Beta5 中根据 beta 版本说明：在 Xcode 9 beta 5 – IDE 中解决

Here is how:

方法如下：

1. Press and hold ?(command) button in keyboard and move/hover mouse cursor on any (start or end) braces. It will automatically highlight, block area.
2. Keep (hold) ?(command) button in pressed condition and click on highlighted area. It will enable quick menu popover window with Foldoption.
3. Select Foldfrom menu list. It will fold your code and shows 3 dots, folding/covering entire block.
4. Now, to again unfold your code block, release ?(command) button and click on 3 dots folding a block.

1. 按住?键盘上的（命令）按钮并将鼠标光标移动/悬停在任何（开始或结束）大括号上。它会自动突出显示，阻止区域。
2. 保持（按住）?（命令）按钮处于按下状态，然后单击突出显示的区域。它将启用带有Fold选项的快速菜单弹出窗口。
3. Fold从菜单列表中选择。它将折叠您的代码并显示 3 个点，折叠/覆盖整个块。
4. 现在，再次展开您的代码块，释放?（命令）按钮并单击折叠块的 3 个点。

35237858 : Code Folding in Xcode 9.1 Only does Entire Functions/Methods

35237858：Xcode 9.1 中的代码折叠仅适用于整个函数/方法

UPDATE, A YEAR LATER…

更新，一年后……

This is fixed in Xcode 10. Code folding is back. Thanks to all those who piled on to the bug report or whatever.

这在 Xcode 10 中已修复。代码折叠又回来了。感谢所有那些堆积在错误报告或其他任何东西上的人。

The new, improved code folding in Xcode 9 or 9.1 seems to only work on an entire function or method. (I'm working in Objective-C today.) This is not very useful. You know, functions or methods are only one curly bracket deep. It is easy to eyeball them. Where I needcode folding is for long control flow blocks – if, else, switch, do, while, or just loose blocks. Please bring it back so I can use code folding as it worked in Xcode 8.

Xcode 9 或 9.1 中新的、改进的代码折叠似乎只适用于整个函数或方法。（我今天在 Objective-C 中工作。）这不是很有用。要知道，函数或方法只有一个大括号深。很容易注意到他们。我需要代码折叠的地方是长控制流块——if、else、switch、do、while 或只是松散的块。请把它带回来，这样我就可以像在 Xcode 8 中一样使用代码折叠。

The ribbon thing, although I thought it was good, others didn't – I can live without it. But code folding needs to work on all curly-bracket code blocksplease.

丝带的东西，虽然我认为它很好，但其他人不认为——我可以没有它。但是代码折叠需要适用于所有花括号代码块。

This doesn't do folding, but it might help you to navigate in the code:

这不会折叠，但它可能会帮助您在代码中导航：

If you want to find out which brackets that go together you can click just behind the start or end bracket, you will then get a one second highlight of both. Or you can double click or either bracket and get permanent highlight of everything between the brackets.

如果您想找出哪些括号放在一起，您可以在开始或结束括号后面单击，然后您将获得两个突出显示的一秒钟。或者您可以双击或任一括号并永久突出括号之间的所有内容。

Xcode 9

As it has already been commented, the code folding in Xcode 9 only works on entire functions. The closest I got to a way to figure out where does a curly brace closes (especially for long foror ifblocks), is by double tapping in the curly brace. This will highlight that block of code until the curly brace closes.

正如已经评论过的那样，Xcode 9 中的代码折叠仅适用于整个函数。我最接近找出花括号关闭位置的方法（特别是对于长括号for或if块），是双击花括号。这将突出显示该代码块，直到花括号关闭。

Of course, this will work much better in Xcode 10 with the new code folding ribbon.

当然，这在 Xcode 10 中使用新的代码折叠功能区会更好。
