Miscellaneous_EchoExecutable/Sources/secho/main.swift:11:11: error: cannot find 'getcwd' in scope
     9 | #endif
    10 |
    11 | let cwd = getcwd(nil, Int(PATH_MAX))
       |           `- error: cannot find 'getcwd' in scope
    12 | defer { free(cwd) }
    13 | let workingDirectory = String(validatingUTF8: cwd!)!

getcwd() is declared in unistd.h, which is in the Android overlay but not in the Bionic module that Swift uses.

The rest may work as import Bionic though, I will do more testing and let you know.
