Mint ????

SPM Git Version Build Status license

A package manager that installs and runs Swift command line tool packages.

$ mint run realm/swiftlint 0.22.0

This would install and run SwiftLint version 0.22.0

Mint is designed to be used with Swift command line tools that build with the Swift Package Manager. It makes installing, running and distributing these tools much easier.

  • ✅ builds are cached globally by version
  • ✅ easily run a specific version of a tool
  • ✅ use different versions of a tool side by side
  • ✅ easily run the latest version of a tool
  • ✅ distribute your own tools without recipes and formulas

Homebrew is a popular method of distributing Swift executables, but that requires creating a formula and then maintaining that formula. Running specific versions of homebrew installations can also be tricky as only one global version is installed at any one time. Mint installs your tool via SPM and lets you run multiple versions of that tool, which are globally installed and cached on demand.

If your Swift executable package builds with SPM, then it can be run with Mint! See Support for details.

Why is it called Mint?

Swift Packager Manager Tools -> SPMT -> Spearmint -> Mint! ????????


Make sure Xcode 9 is installed first.


$ brew tap yonaskolb/mint
$ brew install mint


$ git clone
$ cd mint
$ make

Swift Package Manager


$ git clone
$ cd mint
$ ./build/release/mint

Use as dependency

Add the following to your Package.swift file's dependencies:

.package(url: "", from: "0.1.0"),

And then import wherever needed: import MintKit


Run mint to see usage instructions.

$ mint
  mint [command]

Available Commands:
  install  Install a package
  run      Run a package
  update   Update a package
Use "mint [command] --help" for more information about a command.
  • Install: Installs a package. If it is already installed this won't do anything
  • Run: Runs a package. This will install if first if it doesn't exist
  • Update: Installs a package while enforcing an update and rebuild. Shouldn't be required unless you are pointing at a branch and want to update.

These commands all have 1 to 3 arguments:

  • repo (required): This can be a shorthand for a github repo install realm/SwiftLint or a fully qualified git path install In the case of run you can also just pass the name of the repo if it is already installed run swiftlint. This will do a lookup of all installed packages.
  • version (optional): The git version of the packge. It is usually a tag but can also be a branch. If this is left out the version will default to the latest tag, or if there are no tags then master.
  • command (optional): The command to install or run. This defaults to the the last path in the repo (so for realm/swiftlint it will be swiftlint). In the case of run you can also pass any arguments to the command but make sure the whole thing is surrounded by quotes eg mint run realm/swiftlint 0.22.0 "swiftlint --path source"


$ mint install yonaskolb/xcodegen 1.2.0 "xcodegen --spec spec.yml" # pass some arguments
$ mint install yonaskolb/xcodegen 1.2.0 # use version 1.2.0
$ mint install yonaskolb/xcodegen # use newest tag
$ mint run yonaskolb/xcodegen 1.2.0 # run 1.2.0
$ mint run xcodegen # use newest tag and find xcodegen in installed tools 


If your Swift command line tool builds with the Swift Package Manager than it will automatically install and run with mint! You can add this to your Installing section in the readme:

### [Mint](
$ mint run github_name/repo_name


If your executable name is different from your repo name then you will need to append the name to the above command


The Swift Package Manager doesn't yet have a way of specifying resources directories. If your tool requires access to resources from the repo you require a custom Package.resources file. This is a plain text file that lists the resources directories on different lines:


If this file is found in you repo, then all those directories will be copied into the same path as the executable.
