I use TC 8.1 Professional version.
Xctool is a Mac/iOS platform buildtool.[it is similar to xcodebuild]
In buildstep in project configuration page, xctool is not mentioned in drop-down window.
So I have wriiten perl script to call xctool, but in generated buildlog I dont see any output of xctool. In manual build I see xctool log, but not in TeamCity build.
