How to configure this to make it work with Swift?

[konrad1977]

I cannot get it to work with swift. It hooks in but nothing changes.

If I check my message I can see message like this.

[tree-sitter-langs] Running (git rev-parse --show-toplevel) in /Users/mikaelkonradsson/.emacs.d/elpa/tree-sitter-langs-20211228.1446/
The directory /Users/mikaelkonradsson/.emacs.d/elpa/tree-sitter-langs-20211228.1446/ doesn’t seem to be a git working dir. Grammar-building functions will not work.
tree-sitter-langs: Grammar bundle v0.10.13 was already installed; skipped

And if I check the tree-sitter-tree:

My config block for tree-sitter:

(use-package tree-sitter
  :config
  (add-to-list 'tree-sitter-major-mode-language-alist '(swift-mode . swift))
  (add-hook 'swift-mode-hook #'tree-sitter-mode)
  (add-hook 'tree-sitter-after-on-hook #'tree-sitter-hl-mode))

(use-package tree-sitter-langs
  :after (tree-sitter))

The screenshot shows the syntax tree to the right. That means it's working.

If you mean code highlighting didn't change, that's because it should be provided by another package.
tree-sitter-langs doesn't provide highlighting queries for Swift.

Maybe we/you should add queries (ask the author of the current swift-package) or change to the one I suggested which has queries but for some reason emacs doesn't change the foreground color, only background color. (dunno why though). The latter package is really slow on my intel Mac though. Haven't tried on my M1Max. But it takes around 10 second to view a file.
