Issue Description:

I was able to get some toolchains installed and then use them when launching XCode, but then when I go to actually build and run the SwiftXCTestFunctionalTests scheme, I get this error:

error: can't exec '/Users/jon/code/swift-corelibs-xctest/../llvm/utils/lit/lit.py' (No such file or directory)

And it's true, that file doesn't exist, but I'm not sure what to do about it.

Thanks!
Jon

Hey Jon! In order to build and run XCTest, you need the same source layout as required by the Swift project. In other words, you'll need the following folder structure:

some-folder/
    llvm/
    swift/
    swift-corelibs-foundation/
    swift-corelibs-xctest/

In order for the tests to run, they need to find a file named lit.py from within the llvm directory.

Since it seems like a few people are having trouble getting started with contributing to the project, I'll add some additional instructions to the README.

I've hopefully addressed this in #76 which provides clearer instructions on how to get things working. #77 should also help make it clear that building swift-corelibs-xctest requires the same source layout as the Swift project requires.

Thanks for raising this issue, jonallured (JIRA User)! Please create another one if you run into any more trouble.
