The macOS SDK in Xcode 11.3 is MacOSX11.1.sdk.

> Part of our decision to use "11.0" came from the way that Apple named the SDK: MacOSX11.0.sdk. We will have to see if they change this to MacOSX11.1.sdk in a future version of Xcode and the CLT. If they do, that would represent a change from their previous strategy, and it would be a problem for MacPorts because the SDK path gets baked into some ports. Previously this was ok since the SDK path would stay the same for the life of the OS version, but if it now changes during the life of the OS we may find ourselves needing to rebuild some ports to update their SDK paths.
