[swift-corelibs-dev] Building Foundation in Xcode

Tue Mar 15 13:20:28 CDT 2016

Hey Brian,

So I was able to get a toolchain for OSX and everything seemed to work.
But now I'm trying to test my changes on Linux and it seems my changes are
halting the tests when I run ninja test in the Foundation directory. I
began this discussion on a pull request
<https://github.com/apple/swift-corelibs-foundation/pull/281#issuecomment-196942460>
because I thought this was purely related to the Swift 3 changes, but now
I'm not sure.

Anyway, I try to run the debug tests command that ninja test gives me, but
it says I don't have lldb. I thought I had everything necessary, but I'm
not sure how to get lldb or if it is even necessary. I will note that the
tests work on the master branch of Foundation so it does seem like my
problem, but I'm not sure why the issue is happening. Please view the pull
request I mentioned for a little more detail.

If this is more of a swift-dev issue, I can move the conversation there.

Thanks,
Taylor
