[swift-lldb-dev] Building and running swift-lldb from Xcode not working :(

Hey Todd, thanks for the info!

I was attempting to build from the LLDM scheme. The only errors were the
two I provided, I'll post more information at the bottom. When trying the
"desktop" scheme I get the following:

"debugserver" isn't code signed but requires entitlements. It is not
possible to add entitlements to a binary without signing it.


I don't know if syncing is the issue, I simply git cloned swift-lldb from
github and went to the tag "*swift-3.0-RELEASE"* and built.

more info from LLDB scheme errors:

bootstrapping ninja...

warning: A compatible version of re2c (>= 0.11.3) was not found; changes to
src/*.in.cc will not affect your build.

wrote build.ninja.

bootstrap complete.  rebuilding...
