Description

Syntax coloring specifications for Swift (swift.ts) are out of date and appear to be from Swift 4 (the most recent version is 5.5). For example, here is a short list of keywords not indexed:

• @differentiable(reverse)
• async
• @escaping
• @inlinable
• await
• associatedtype
• @unchecked
• rethrows

A list of language keywords can be found here, although the keywords that start with @ are not listed. There are numerous @ keywords, and it isn't feasible to include all of the ones starting with underscores. However, the ones that start with alphabetic characters should be possible to tabulate.

Monaco is the engine behind Google Colab's syntax coloring, and I am concerned because my effort to revive Swift support is negatively impacted by incorrect syntax coloring. Colab is currently restricted to Monaco 0.27.0, so it won't benefit from this correction immediately (the currently version is 0.31.0). Since 0.27.0 was released a few months ago, I expect Google to update to a newer version in the time frame of a few months.
