[Homebrew] Error: swiftgen has been disabled because it does not build!

[batkov]

Homebrew is not installing swiftgen.

I've tried installing older formulas, like brew install swiftgen@6.6.0, but it is not helping.

$ brew update
Already up-to-date.
$ brew install swiftgen
Error: swiftgen has been disabled because it does not build!

Try this. #1030 (comment)

@isgallagher this workaround worked.

Copying for other unfortunate devs:

curl -Lo /tmp/swiftgen.rb https://raw.githubusercontent.com/iMichka/homebrew-core/17ae00b4bf1640cc544eae5f6eec03775c09420b/Formula/swiftgen.rb && brew install /tmp/swiftgen.rb && rm /tmp/swiftgen.rb

I've tried to replace brew install swiftgen with this command. However receiving an error and warning on the console:

Error: Failed to load cask: /tmp/swiftgen.rb
Cask 'swiftgen' is unreadable: wrong constant name #<Class:0x000000010ff17768>
Warning: Treating /tmp/swiftgen.rb as a formula.

How can I resolve this issue?

Already installed? Try ... && brew reinstall /tmp/swiftgen.rb && ... 😉

We've replaced it with mint install.
brew install mint
mint install SwiftGen/SwiftGen

We've replaced it with mint install. brew install mint mint install SwiftGen/SwiftGen

Although this worked for me also, my project setup couldn't find the "swiftgen" command, even if I could run it from terminal. If you need specific homebrew installation, this worked for me:

1. disable homebrew's check update 'export HOMEBREW_NO_INSTALL_FROM_API=1', otherwise the installation will overwrite the file edited below
2. Manually change the repository file 'brew edit swiftgen', which will automatically edit the repository file using vim
3. find 'disable! date: "xxxx", because: xxxx', add # before it, comment out this line
4. ':wq' Save and exit edit
5. 'brew install swiftgen' to install

brew install swiftgen

is part of our ci pipeline and I dont really want to make the curl solution the permanent fix. Will this be resolved so we can use brew again ? I tried mint but I had issues using swiftgen afterwards.

We've replaced it with mint install. brew install mint mint install SwiftGen/SwiftGen

I am not able to get mint's install to actually work.

SwiftGenCLI/resource_bundle_accessor.swift:11: Fatal error: could not load resource bundle: from /Users/removed/.mint/bin/SwiftGen_SwiftGenCLI.bundle or /private/var/folders/_8/cr5ngqns1n38s7l4tg3crv2m0000gn/T/mint/github.com_SwiftGen_SwiftGen/.build/arm64-apple-macosx/release/SwiftGen_SwiftGenCLI.bundle zsh: trace trap ~/.mint/bin/swiftgen

But it works when I use the curl brew install method.

Problem should be fixed once the homebrew-core PR gets merged 🤞

Sorry for the inconvenience.

[batkov]

brew install swiftgen works now. Thanks
