[swift-corelibs-dev] Building Foundation in Xcode

[Brian Gesiak]

Hello Pushkar,
One idea that comes to mind: are you launching Xcode 7.2 using a recent Swift toolchain? To do so, follow the instructions on this page: https://swift.org/download/#latest-development-snapshots
Specifically, you'll want to launch Xcode using the xcrun launch-with-toolchain command.
Forgive me if this isn't the problem--I'm not at a computer right now, but that error message vaguely reminds me of what happens when one tries to build Foundatoon with an older version of Swift.

I am very new to Xcode and  tried building Foundation and running TestFoundation in Xcode 7.2.1, using the instructions given here.
In step 3, Foundation doesn't build because Xcode reports a compilation failure in NSObjCRuntime.swift (please refer to the attached snapshot):Use of unresolved identifier '_typeByName'
I can see that this function is defined outside of the Foundation project, in the swift project (stdlib/public/core/Misc.swift). I think there are other functions defined in the stdlib and used in Foundation. I am not sure why this particular symbol causes a problem.
Could someone please tell me how the symbol could be imported so that Foundation could be compiled and linked?
