SwiftGen 6.5.1 crash (installed via Mint)

[goodocy]

Hi.
Make a good tool, so I always use it well

Crash problems are found and reported.

image.yml

xcassets:
  inputs:
    - Resource/Test.xcassets
  outputs:
    - templateName: swift5
      output: Image/Image.swift

then

SwiftGenCLI/resource_bundle_accessor.swift:11: Fatal error: could not load resource bundle: from /Users/user/.mint/bin/SwiftGen_SwiftGenCLI.bundle or /private/var/folders/hy/_f54gj0n1ns2dttw7d19rl0m0000gn/T/mint/github.com_SwiftGen_SwiftGen/.build/arm64-apple-macosx/release/SwiftGen_SwiftGenCLI.bundle
[1]    74018 trace trap  swiftgen config run --config image.yml

and i found same result ( happens anywhere (with or without swiftgen.yml ) )

swiftgen template list

SwiftGenCLI/resource_bundle_accessor.swift:11: Fatal error: could not load resource bundle: from /Users/user/.mint/bin/SwiftGen_SwiftGenCLI.bundle or /private/var/folders/hy/_f54gj0n1ns2dttw7d19rl0m0000gn/T/mint/github.com_SwiftGen_SwiftGen/.build/arm64-apple-macosx/release/SwiftGen_SwiftGenCLI.bundle
[1]    74610 trace trap  swiftgen template list

after a little analysis, I got some hints

swiftgen bin

lrwxr-xr-x  1 user  staff    80B Dec  1 19:52 swiftgen -> /Users/user/.mint/packages/github.com_SwiftGen_SwiftGen/build/6.5.1/swiftgen

/Users/user/.mint/packages/github.com_SwiftGen_SwiftGen/build/6.5.1
drwxr-xr-x  3 user  staff    96B Dec  1 19:52 SwiftGen_SwiftGenCLI.bundle
-rwxr-xr-x  1 user  staff   5.1M Dec  1 19:52 swiftgen

And after moving to the actual path

./swiftgen template list -> success
swiftgen template list -> fail

It seems that swiftgen does not properly recognize the SwiftGen_SwiftGenCLI.bundle path when installing with mint

please check

Hi @goodocy

There seems to be something wrong with your installation, the path to the bundle that Swift is trying to load is wrong. Note that SwiftGen doesn't do this, the system (Swift / SPM) does it for us.

Mint itself does not support SPM resource bundles yet, so we had to add a workaround for it with our 6.5.0 release, which was fixed in 6.5.1. See the issue here and the related Mint issue.

Make sure you're using the latest Mint version, and if needed reinstall it & SwiftGen. If the issue persists, I'd recommend creating an issue in the Mint repo.

Same problem for me.

me too in 6.5.1.

As I said before, this is (afaik) a Mint issue, not a SwiftGen issue. Going to close this for now.

I think this issue still is not resolved in any way, even if it hasn't anything to do with SwiftGen. It doesn't work and we need to think about a possible fix or at least a workaround. What do you think guys?

Here is the essence of the issue:
~/.mint/bin contains a symlink called swiftgen which links to the actual bin ~/Users/letsbundle/.mint/packages/github.com_SwiftGen_SwiftGen/build/6.6.2/swiftgen.
Alongside with swiftgen in the original bin path SwiftGen_SwiftGenCLI.bundle is located.

When calling swiftgen from commandline somehow the binary/swift/spm expects SwiftGen_SwiftGenCLI.bundle to be located inside ~/.mint/bin/ where the symlink is located.

Copying the bundle to ~/.mint/bin/ solves the crash.

This needs another fix in some way.

Env:

mint --version
Version: 0.17.2

swiftgen --version
SwiftGen v6.6.2 (Stencil v0.15.1, StencilSwiftKit v2.10.1, SwiftGenKit v6.6.2)

I second @Fab1n that this issue is not resolved or suffering a regression.

❯ mint --version
Version: 0.17.5
❯ swiftgen --version
SwiftGen v6.6.2 (Stencil v0.15.1, StencilSwiftKit v2.10.1, SwiftGenKit v6.6.2)

Workaround

❯ ln -s ~/.mint/packages/github.com_SwiftGen_SwiftGen/build/6.6.2/SwiftGen_SwiftGenCLI.bundle ~/.mint/bin/SwiftGen_SwiftGenCLI.bundle

I'm also facing this issue. The workaround worked for me.
