SPM Backend experimental

You may install executables managed by Swift Package Manager directly from GitHub or GitLab releases.

The code for this is inside of the mise repository at ./src/backend/spm.rs.

Dependencies

This relies on having swift installed. You can either install it manually or with mise.

NOTE

If you have Xcode installed and selected in your system via xcode-select, Swift is already available through the toolchain embedded in the Xcode installation.

Usage

The following installs the latest version of tuist and sets it as the active version on PATH:

$ mise use -g spm:tuist/tuist
$ tuist --help
OVERVIEW: Generate, build and test your Xcode projects.

USAGE: tuist <subcommand>
...

The version will be set in ~/.config/mise/config.toml with the following format:

[tools]
"spm:tuist/tuist" = "latest"

Supported Syntax

Description	Usage
GitHub shorthand for latest release version	spm:tuist/tuist
GitHub shorthand for specific release version	spm:tuist/tuist@4.15.0
GitHub url for latest release version	spm:https://github.com/tuist/tuist.git
GitHub url for specific release version	spm:https://github.com/tuist/tuist.git@4.15.0

Other syntax may work but is unsupported and untested.

Tool Options

The following tool-options are available for the backend — these go in [tools] in mise.toml.

provider

Set the provider type to use for fetching assets and release information. Either github or gitlab (default is github). Ensure the provider is set to the correct type if you use shorthand notation and api_url for self-hosted repositories as the type probably cannot be derived correctly from the URL.

[tools]
"spm:patricklorran/ios-settings" = { version = "latest", provider = "gitlab" }

api_url

Set the URL for the provider's API. This is useful when using a self-hosted instance.

[tools]
"spm:acme/my-tool" = { version = "latest", provider = "gitlab", api_url = "https://gitlab.acme.com/api/v4" }

filter_bins

Restrict which executable products are built and linked from the package. When unset, every executable product declared in Package.swift is built and symlinked into bin/ (the default behavior).

Useful when a package ships helper executables (e.g. test harnesses) that you don't want on your PATH. Filtering happens before swift build, so unwanted products are never built.

Accepts a TOML array or a comma-separated string. If any listed name does not match an executable product in the package, installation fails with a clear error.

[tools]
"spm:swiftlang/swiftly" = { version = "latest", filter_bins = ["swiftly"] }
# or
"spm:swiftlang/swiftly" = { version = "latest", filter_bins = "swiftly" }
