Considerations

Obviously the result theme will not match 1:1 because IDEs parse code differently.

In addition, VSCode allows for much more complex themes that are language/framework-aware so a specific theme might look different when rendering JS code vs TypeScript code.

This tool will only convert the colors that aren't associated with a specific language.

In my testing, the results are decent, but you might need to edit the theme to reach perfection ;)

OVERVIEW: A command-line tool for converting VSCode themes files into Xcode theme files

USAGE: transmog <theme-file-path-or-url> [--output <output>] [--skip-color-profile-correction]

ARGUMENTS:
  <theme-file-path-or-url>
                          Path or URL of the VSCode theme file (.json). GitHub links are also supported. 

OPTIONS:
  -o, --output <output>   Output directory path (optional) (default:
                          ~/Library/Developer/Xcode/UserData/FontAndColorThemes/)
  -s, --skip-color-profile-correction
                          Skip the color profile correction of VSCode theme values.
                          This will cause theme colors to look different in Xcode from what they appear like in
                          VSCode.
