    ld: -pie can only be used when targeting iOS 4.2 or later
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

Your deployment target is set to 4.0 but -pie can only be used when targeting iOS 4.2 or later as clearly stated by the above error message. Try setting your deployment target to 4.3. This is the lowest deployment target supported by Xcode 6.
