XCPretty
XCPretty is a fast and flexible formatter for xcodebuild.
It does one thing, and it should do it well.
Installation
$ gem install xcpretty
Usage
XCPretty is designed to be piped with xcodebuild and thus keeping 100% compatibility with it.
This means, when xcodebuild works, xcpretty works.
It's even a bit faster than xcodebuild only, since it saves your terminal some prints.
Formats
simple (default)

test (RSpec style, shown above)

tun / tap (not yet implemented. possible solution for most CI servers)
XCPretty isn't
Unlike xctool, xcpretty isn't a build tool.
It relies on xcodebuild to do the build process, and it formats the output.
Why?
There are many usages of this tool. Let me give you some ideas:
- Xcode's test tools are close to useless. Failures in a sidebar, non-dettachable console,... You can use
xcprettyto build your next Xcode test runner plugin - Run tests each time you hit save. The output is minimal, so go and wire it up with Kicker or Guard and be a real hipster!
- Mine Bitcoins. You can't with this tool, but you'll be so productive that you can earn all the money and buy them!!!1!
