I have workspace with 5 projects and 2 schemas that build 2 version of my application. 4 projects are static libraries and the last one is application with 2 schemas.
When I attach xcode build plugin with to build my application without defining SYMROOT and Build output directory .app file is build correctly but when .ipa file stated to build I have error that build directory is not created.
When I define Build output directory as relative path linker prints error that cannot find my static libraries to link because output directory was different for every project.
I solved this issue defining absolute path to SYMROOT variable.
