Compiling from source?

I was able to solve my issue. For any others with this issue here is the solution:

  1. Open Xcode Beta
  2. Go to Preferences
  3. Go to Locations Tab
  4. In Command Line Tools dropdown select Xcode 11.0

I have both Xcode 10 and 11 installed and it was still trying to use Xcode 10 command line tools for builds. With this change the Swift-APIs compile successfully.
