[swift-corelibs-dev] [XCTest] Cannot build using XCode

Hi Brian,

Thanks for you response.

Still I cannot compile corelibs-xctest with xcode-beta. It seems the error
is too generic to debug! If xctest is not yet configured against xcode 8
beta, probably, I will wait. At this point, I am lazy to create my own
toolchain, since my last attempt went bust!


The steps I followed

1. delete swift/build
2. utils/update-checkout
3. sudo  xcode-select -s
/Applications/Xcode-beta.app/Contents/Developer
4. utils/build-script -r -t   (success)
5. utils/build-script -R.    (success)
6.
$ cd swift-corelibs-xctest
$ ../swift/utils/build-script --preset corelibs-xctest


Environment

*Swift Version: Swift version 3.0 (swiftlang-800.0.30 clang-800.0.24)*
Xcode Environment: Version 8.0 beta (8S128d)
Python Version: Python 2.7.10



The Error

CompileSwift normal x86_64
