Basically what we are going to do is use and profit from NSURLRequests being conformant to NSCoding, 
and a little known API from NSURLProtocol which allows us attach info to requests.
*/

//Step 0: For the purpose of this gist, we'll already have a background session setup and assume a bunch of stuff.
NSURLSession *bgSession = [NSURLSession magicMethodWhichGivesMeTheAlreadySetupSession]; //Geeez, Methods are long in Obj-C.

//IMPORTANT: Request must be mutable in order for this to work. Got an immutable one. Make a copy. Can't? Well, Make it so!.
//Step 1: Setup your basic request.

Build Swift first using utils/build-script -R, other settings will need different directories below. Add these lines to ~/.bashrc, call with run-test path/to/test:

LLVM_DIR="/path/to/Swift/llvm"
SWIFT_BUILD_DIR="/path/to/Swift/build/Ninja-ReleaseAssert/swift-macosx-x86_64"

run-validation-test() {
    $LLVM_DIR/utils/lit/lit.py -a --param swift_site_config=$SWIFT_BUILD_DIR/validation-test-macosx-x86_64/lit.site.cfg $1
}
