Time to be productive with Xcode!<\/p>\n\n\n\n

Define your own shortcuts<\/h3>\n\n\n\n

If there’s only one thing to remember from this post, that is to define your own keyboard shortcuts. I find that some handy shortcuts are associated with commands that are seldom used. Working with a French keyboard I also need to change some defaults anyway.<\/p>\n\n\n\n

So go to Xcode > Settings > Key Bindings and experiment.<\/p>\n\n\n\n

Move between subwords<\/h3>\n\n\n\n

You probably know \u2325\u2190 and \u2325\u2192 to move from one word to the other. But did you know ^\u2190 and ^\u2192 to move between subwords? Extremy useful with CamelCase symbols.
macOS might already use the same shortcuts to navigate between Spaces of Mission Control (I favorise Xcode).<\/em><\/p>\n\n\n\n

Missing text commands<\/h3>\n\n\n\n

I’m desperate with Xcode still missing some commands that are widely available in other text editors. At last, and after begging for 15 years, Xcode 14 can finally duplicate a line (\u2318D)! But I still see too many people using their mouse to select a whole line of code.<\/p>\n\n\n\n

Look for the TextPlus Xcode extension on the Mac AppStore and install it. Now assign the following keyboard shortcuts:<\/p>\n\n\n\n

Copy line<\/td>^C<\/td><\/tr>
Cut line<\/td>^X<\/td><\/tr>
Clear line<\/td>^\u2326<\/td><\/tr>
Clear line and Paste<\/td>^V<\/td><\/tr>
Duplicate Line Up<\/td>\u2325\u21e7\u2191<\/td><\/tr>
Duplicate Line Down<\/td>\u2325\u21e7\u2193<\/td><\/tr>
Insert Line Above<\/td>^\u2325\u2191<\/td><\/tr>
Insert Line Below<\/td>^\u2325\u2193<\/td><\/tr><\/tbody><\/table>

Then you can copy\/cut\/paste\/delete a whole line of code without selecting it. Unfortunately not with \u2318C \/ \u2318X \/ \u2318V.<\/p>\n\n\n\n

I adopted the same keyboard shortcuts than Visual Studio code to duplicate lines.<\/p>\n\n\n\n

Show Document Items<\/h3>\n\n\n\n

This command is misnamed but you probably already know it. It’s the little menu that pops-up when you click the “Breadcrumb” bar.<\/p>\n\n\n\n

\"Xcode:<\/a><\/figure>\n\n\n\n

First: did you know that you could type to filter it ?<\/p>\n\n\n

\n
\"Xcode:<\/a><\/figure><\/div>\n\n\n

And now is the second trick: the Xcode command which corresponds to this menu is “Show Document Items”. Associate it with a very accessible keyboard shortcut, for example the key on the top left of your keyboard. That will be \u2318` on a US keyboard or \u2318@ on my French keyboard.<\/p>\n\n\n\n

Vim mode<\/h3>\n\n\n\n

You may activate the Editor > Vim mode<\/em> if you’re that kind of person. There are no Visual<\/em> or Block<\/em> modes, which I don’t care much for, but I do miss relative line numbering.<\/p>\n\n\n\n

Tests shortcuts<\/h3>\n\n\n\n

Use \u21e7\u2318U to build the current test target.<\/p>\n\n\n\n

Use ^\u2325\u21e7U to launch the current test class.<\/p>\n\n\n\n

Use ^\u2325\u2318G to relaunch the last test (very useful when writing a test).<\/p>\n\n\n\n

Test counterpart<\/h3>\n\n\n\n

Say you’re editing MyFile.swift. Press ^\u2318\u2191 (Navigate > Jump to Next Counterpart) twice to go to MyFileTests.swift.<\/p>\n\n\n\n

Snippets<\/h3>\n\n\n\n

Create snippets for extracts of code which are frequent, hard to type or hard to remember.<\/p>\n\n\n\n

To create a snippet, select some code then Editor > Create code snippet<\/em>. Use <#placeholder#> where appropriate.<\/p>\n\n\n\n

Here are some of my favourite snippets for Swift:<\/p>\n\n\n\n

Code<\/strong><\/td>Completion keyword<\/strong><\/td><\/tr>
guard let self else { return }<\/code><\/td>guards<\/code><\/td><\/tr>
@testable import MyApp<\/code><\/td>myapp<\/code><\/td><\/tr>
\/\/\/ :inheritdoc:<\/code><\/td>inherit<\/code><\/td><\/tr>
\/\/ MARK: <#mark#><\/code><\/td>mark<\/code><\/td><\/tr>
\/\/\/ :nodoc:<\/code><\/td>nodoc<\/code><\/td><\/tr>
\/\/ swiftlint:disable:this <#rule#><\/code><\/td>lintdis<\/code><\/td><\/tr>
