You must be running Xcode in Snow Leopard and install Xcode from the Snow Leopard disc that you got at WWDC. If you did not get a Snow Leopard disk, then you are out of luck unless you find one elsewhere.
您必须在 Snow Leopard 中运行 Xcode，并从您在 WWDC 获得的 Snow Leopard 光盘安装 Xcode。如果您没有得到 Snow Leopard 磁盘，那么除非您在别处找到它，否则您就不走运了。

on Xcode Version 6.1 (6A1052d), you just need to double click on one of the parenthesis and the entire code that the parenthesis is scoping out is highlighted.
在 Xcode 版本 6.1 (6A1052d) 上，您只需要双击其中一个括号，括号内的整个代码就会突出显示。
for example, if you have a code like the one below and you double click '{' or '}' bracket the entire code in their scope is highlighted :
例如，如果您有一个类似于下面的代码，并且您双击“{”或“}”括号，则会突出显示其范围内的整个代码：
if(condition == true)
{
//do something
}
如果（条件 == 真）
{
//do something
}

In XCode 9 the only solution is to put mouse over parentheses while pressing command button. Only this works.
在 XCode 9 中，唯一的解决方案是在按下命令按钮的同时将鼠标放在括号上。只有这个有效。

To extend the other answers it is possible to roll in/out code inside brackets.
要扩展其他答案，可以在括号内滚入/滚出代码。

Please have a look at below answer for Xcode 9.0 and above:
请查看以下 Xcode 9.0 及更高版本的答案：
Xcode highlights an opening delimiter (brace, bracket, parenthesis) when you move the cursor left-to-right over the matching closing delimiter. The highlight animation lasts about 1 second total, which is plenty in the case where you need a hint (and as you say the other delimiter is nearby).
当您将光标从左到右移动到匹配的结束定界符上时，Xcode 会突出显示一个开始定界符（大括号、方括号、圆括号）。高亮动画总共持续大约 1 秒，这在您需要提示的情况下已经足够了（正如您所说的另一个分隔符在附近）。
If you need a more persistent indication, you can double-click either the opening or the closing delimiter, and Xcode will select both delimiters and their contents. (You can also use this, for example, to get quickly to one delimiter from another, even if they're far apart — double-click the delimiter you can see, use the left or right arrow to get the other end of the selection.)
如果您需要更持久的指示，您可以双击开始或结束定界符，Xcode 将选择这两个定界符及其内容。（例如，您也可以使用此功能从另一个分隔符快速到达另一个分隔符，即使它们相距很远 - 双击您可以看到的分隔符，使用向左或向右箭头获取选择的另一端.)
