I installed the latest Xcode : v10 (10A255) on macOS Mojave v10.14 (18A391)

> swift --version
Apple Swift version 4.2 (swiftlang-1000.0.37.1 clang-1000.10.44)

> swift build

used to build my project (which uses other packages)

but now I get:

> swift build
error: terminated(72): xcrun --sdk macosx --find xctest output:

I'm not trimming anything here; there's nothing after "output:" the following line is empty.

I can create a new package "swift init --type executable"; but I'll have the same error if I try to build it.

I can't tell what's wrong here and my internet search is unfruitful so far.

Did you do a Clean Build Folder ?

  When I tried making the new package, there would not have been any existing previous build history/folder.

Listing my findings to any future reader:

$ xcode-select -p /Library/Developer/CommandLineTools
I tried:

$ xcode-select --install xcode-select: error: command line tools are already installed, use "Software Update" to install updates

$ xcode-select --reset

$ swift build
properly compiled the package.
