Getting a Segmentation fault: 11 with Swift 5.2 when using FileManager.default.currentDirectoryPath

Turns out that in this case, the problem was in rogue overlay dylibs that were in place because I've been using SwiftGen.

The solution is to either uninstall SwiftGen by calling

brew uninstall swiftgen

or following Nikolaj's answer from Swift bug tracking system by reinstalling SwiftGen with

--build-from-source

option and removing the dylibs from "lib" folder.
