fix: Run swift-format [1/4]

[MahdiBM]

Description

I'm using VSCode/Cursor and everytime a format-on-save is triggered, the whole file gets formatted.
This is not good because I have some incoming PRs that make logic changes, and I don't want to make them harder to review that they already are.
If needed i can set up swift-format CI in a separate CI to make sure the project remains swift-formatted.

Feel free to review on your own schedule.

How Has This Been Tested?

Please describe the tests that you ran to verify your changes.

Minimal checklist:

• I have performed a self-review of my own code
• I have added DocC code-level documentation for any public interfaces exported by the package
• I have added unit and/or integration tests that prove my fix is effective or that my feature works

Need to check that this is workable with Xcode's formatting too - otherwise the reverse problem will exist...

[MahdiBM]

@hassila Xcode doesn't have any particular problem with this I think.
I haven't used Xcode much lately, but I also never noticed it making problems.
Usually Xcode doesn't force it's own formatting.

The Apple repositories have all moved to enforcing swift-format and I know not all of them use non-Xcode IDEs.

I'll check to make sure soon, but I'm fairly certain we should be fine.

Thanks!

Probably should add some docs if you are up for it for contributions or run CI job with swift-format -i --recursive .. WDYT?
Ping @freef4ll wrt CI.
