A Couple More Xcode Keys

There are a handful of Xcode keyboard shortcuts that I find particularly useful. Although the keys are documented, some folks have apparently not come across them, yet. Hopefully, using these keys will help your productivity as much as it does mine.

First, let’s consider Code Completion. Two keys here are particularly useful. +. (control + period) cycles through the list of possible completions for the token that you’ve typed, while pressing brings up the full list of possible completions. The Xcode menu suggests + (alt/option + escape) for this action, but just seems to work fine.

If code completion doesn’t seem to be working for you, be sure to check the setting for the Automatically Suggest menu in Xcode’s Code Sense preferences.

Another shortcut that I use frequently is +/ (control + slash), which cycles between the placeholders highlighted by Code Completion. Sometimes you can also accomplish this with the arrow keys, but +forward slash always works.

Happy Xcoding!

Shortcut for “Go to Counterpart”

It’s crunch time for getting the first BluMtnWerx apps ready for release, so I’ve been neglecting my writing responsibilities. This will be a short one, as I’ve got lots of code to write (OK, debug) before I sleep. Anyway, when I’m in the “code ’til I drop” mode, I find myself using Xcode’s “Go to Couterpart” quite a bit. This is, at least partly, because I get too tired to actually remember what’s in the header file. Anyway, I finally got fed up with moving the cursor up to the icon every time I wanted to toggle between header and source files, so I went looking for a shortcut. What did we do before Google? When I first started using Xcode, I tried to find an answer in the program’s documentation, but I got frustrated and gave up. Of course, a fraction of a second with Google gave me the answer:

<Command>+<Option>+↑ (that’s <UpArrow>)

…toggles between header and source. As the result is a toggle, a similarly modified ↓ isn’t required to invert the operation. If I’d looked through Xcode’s menus, I could also have dug it up – it’s under the View menu – but I’m not a menu guy, I’d never even looked at the View menu until I started this post.

That’s it for today’s tip, enjoy…

Postscript: I tried to use angle brackets: 〈 and 〉 in this post. Every browser that I checked, except IE, handled them just fine. Sigh…
