Allow optional filtering out output from xcodebuild through xcpretty for less logs and clear output.
It is not unusual to see multi-MB logs from XCode build which makes build log navigation (or just plain opening of) a pain because you have to download all this log.

Optional flag to pipe output through xcpretty (with some very basic options) would tremendously increase readability of output, reduce build log size and make Jenkins even more fun to use.

As of now, the best option is to use manual shell scripts and avoid XCode plugin - log size and readability could be that bad.
