Installation problems on Mojave, what OS versions are supported?

[AugustM]

The installation instructions are incomplete. Downloading the code and unzipping does not provide an executable version to place in a $PATH directory. The only executable file is "LICENSE", which is a text file.

Then I found the Github Releases section and successfully downloaded the binary. However, when I run it with no options, just "SpaceInfo" in a Mojave terminal window, I get:

dyld: lazy symbol binding failed: Symbol not found: _swift_getTypeByMangledNameInContextInMetadataState
  Referenced from: /Users/amohr/bin/SpaceInfo (which was built for Mac OS X 12.0)
  Expected in: /usr/lib/swift/libswiftCore.dylib

dyld: Symbol not found: _swift_getTypeByMangledNameInContextInMetadataState
  Referenced from: /Users/amohr/bin/SpaceInfo (which was built for Mac OS X 12.0)
  Expected in: /usr/lib/swift/libswiftCore.dylib

Abort trap: 6

I downloaded the code and got a file called SpaceInfo-main, unzipped it, and found an XCode project. I opened it in XCode 11.3.1, changed the Build Target to macOS 10.14 and the build failed. I could not find any error messages (but that could be user error as I've only been using XCode for a little while).

What macOS versions will the binary run on?
What versions of macOS can the code be compiled on/for and what other changes might be needed (e.g. what version of Swift is needed)?

I had previously built and used this on MacOS 11, 12, and now 13. Today I've updated the project to build correctly on Ventura and I also tested on an old MacBook Air running 10.13.6 where I ran into similar problems as you describe with the older MacOS not knowing anything about the swift libraries the executable requires.

After a bit of Googling I was able to get things working on 10.13.6 by installing "Swift 5 Runtime Support for Command Line Tools"

Hopefully this approach works for you as well on 10.14...
