Awesome
Swift Echo
What's this?
Basic stuff here, but this little project illustrates a few things that I want to remember for cross-platform Swift development:
-
how to setup a Swift Package Manager project that compiles on macOS and Linux, using build directives to conditionally import
Glibc
vsDarwin.C
-
how to setup a Makefile so you can test building and running on macOS and Linux OS, from the comfort of your macOS command line thanks to Docker
-
basic interop between Swift and C-oriented system API, using
getline
to echo standard input
Things to try:
$ make build_osx
$ make run_osx # then type a line and have it echoed back
$ make build_linux # if you have Docker installed...
$ make run_linux
$ swift package generate-xcodeproj # to edit in Xcode
