      MacOS 10.15.3 

      Apple Swift version 5.2 (swiftlang-1103.0.32.1 clang-1103.0.32.29)

       

      Description

      I've got a custom Swift script that is similar to the following:

       

      #!/usr/bin/env xcrun --sdk macosx swift
      
      import Foundation
      
      let path = FileManager.default.currentDirectoryPath
      

      On Swift 5.1 and lower it runs just fine, but upon updating to Swift 5.2, I get

      0. Program arguments: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift -frontend -interpret test.swift -enable-objc-interop -stack-check -sdk /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk -color-diagnostics -module-name test

      Is this a bug, or am I doing something wrong?
