However when I do 'which swift' in my terminal it points to a binary in /usr/bin.  When I run 'swift build --help' I get '<unknown>:0: error: no such file or directory: 'build'' so clearly it is not the right swift binary.  I am not sure where the binary came from in /usr/bin but I cant delete it because OSX is telling me that it is needed by the operating system.  Has anyone encountered this before?

OS X puts forwarding stubs for various developer tools into /usr/bin that launch the corresponding tools from the active Xcode or Command Line Tools installation. IIRC you're supposed to use xcode-select, or change the toolchain within Xcode itself, instead of putting the toolchain directly in your path. You can then use `xcrun swift` to run swift with the correct environment set up.
