Fix indentation for entire project in Xcode 7?

Question

I've inherited a huge iOS project which is all using two-space indenting. I need that to be four-space indenting. I know that I can hit Ctrl+I per file, but I'm wondering whether Xcode (or AppCode, for that matter) has a means of re-indenting every source file in the entire project in one whack.

Failing that, I’m wondering how I might go about writing some sort of script (using Automator, or perhaps an Xcode plugin, or even something on the command line) to achieve this without going insane.

This is possibly outdated by now, but see if the answers in this thread can be of help; http://stackoverflow.com/questions/3216426/is-it-possible-to-set-indent-settings-in-xcode-per-project-or-per-file-even. — dfrib, Dec 09 '15 at 16:29
No good I’m afraid – the options there don’t actual re-factor anything, they just set project preferences and won’t modify code. — Luke, Dec 09 '15 at 16:32
That's too bad... I guess you could download a trial version of JetBrains AppCode and let their code formatter do the job, then return to Xcode. Not the solution you were hoping for though, I'm sure x) https://www.jetbrains.com/objc/features/ — dfrib, Dec 09 '15 at 16:40
Formatting/indentation/codestyle support in Xcode has always been (and continues to be) significantly lacking. I don't know how Apple does it. — Craig Otis, Dec 09 '15 at 16:40
Take a look at clang-format. It may be able to do what you're looking for. It's available in brew. — Rob Napier, Dec 09 '15 at 16:43
AppCode doesn't seem to do the job either, I have that on my machine and I can't find options that will ONLY indent. — Luke, Dec 09 '15 at 16:45

You can use SwiftFormat to make indentation on all of your project .swift files

$ brew install swiftformat
$ cd <path to your project>
$ swiftformat .

Refactoring and Re-Indenting are quite different operations. I'm making this distinction so that folks newer to coding / coding IDEs aren't confused.

Refactoring: taking an existing variable / block of code and propagating changes through the project where it is used. For example, refactoring (renaming) a variable foobar to foobar2 would automatically find all cases where foobar is used and change it to foobar2

Re-indenting: changing the structure / flow / alignment of the code to match the desired coding style for clarity / correctness, particularly ensuring that nested items like conditionals and loops are neatly aligned to improve code readability.

You can use SourceKit, but it is a bit complicated to use, so instead you can use SourceKitten which is a wrapper on top of SourceKit. You have to search for all .swift files and run sourcekitten format --file path/to/file

find . -type f -name "*.swift" | while read line; do
  sourcekitten format --file "$line";
done

So, I did manage this with AppCode in the end. We ended up doing a wider-scale refactor using AppCode’s various tools. I’m not sure if I would’ve been able to do JUST the spacing, their Twitter support suggested that I could, but didn’t detail exactly how.
