Definitely +1.

I've had a long discussion about this from one of the Xcode developers a few months back, pointing out that given how long has Xcode been around it has really really poor support for customizing the codestyle.

I really like what AppCode from JetBrains does - it allows you to even apply the code style automatically on save and allows you to customize it and have teams share the code style - something like StyleCop in C# (though I've never used it).

I do use Swimat (Xcode plugin) fairly often, which enforces spaces between operators, etc.

I've also tried out tailor (https://tailor.sh <https://tailor.sh/>) which is fairly nice, but can be too strict at times.

According tohttps://bugs.swift.org/browse/SR-146 <https://bugs.swift.org/browse/SR-146>, we now have decoupled indenting logic from SourceKit into its own library, and a "swift-format" tool is in the making.

For example, with my changes you could decide how a case label should be indented with respect to its parent switch context, among other things. The current, hard coded indenting decisions in libIDE could be named the "Apple" style, just like Clang supports Google, LLVM, Mozilla, coding styles for C++. Also, this is something that can be supported by external tools like Xcode quite easily.
