Answer 1

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.

The version of Xcode needed is 3.2 and the other components in the about page are:

Component versions

• Xcode IDE: 1600.0
• Xcode Core: 1599.0
• ToolSupport: 1591.0

Answer 2

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.

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 :

if(condition == true) { //do something }

Could you please elaborate more your answer adding a little more description about the solution you provide? – Vagary

This is really helpful even though apple suggests to click on the left side of the line developer.apple.com/library/ios/recipes/… – Subsonic

Answer 3

Choose editor -> code folding -> focus

Answer 4

Edit

In XCode 9 the only solution is to put mouse over parentheses while pressing command button. Only this works.

To extend the other answers it is possible to roll in/out code inside brackets.

Choose Editor > Structure > Balance Delimiter

Nevertheless, as already written earlier, the major feature is

Editor > Code Folding > Focus Follows Selection

Answer 6

Please have a look at below answer for Xcode 9.0 and above:

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).

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.)

One second is far from plenty the moment SwiftUI arrived and you are pretty much forced to hold large chunks of meaningful code on your views, or you have a somewhat complex method. It's a very bad UX choice to make it dissappear and to go use the sloppy way of click, hold cmd and scroll to look for it with no visible hint on the scrollbar or the edge for example. But hey, it's XCode, what else can we expect. – Weatherproof

Answer 7

With latest xcode13 we can permanent active this option with

"Xcode" --> "Preference" ---> "Text Editing" and by enabling "Code folding ribbon"
