1. You don't have to use it all, but someone will. And there are over 200 keywords in the language: https://x.com/jacobtechtavern/status/1841251621004538183

2. On top of that many of the features in the language exist not because they were carefully designed, but because they were rushed: https://news.ycombinator.com/item?id=47529006

That number is unfairly exaggerated. The list includes ~40 internal keywords used only by language developers, plus dozens of tokens that would be called preprocessor directives, attributes, or annotations in other languages (e.g. `canImport` as in `#if canImport(...) #endif`; `available` and `deprecated` as in `@available(*, deprecated) func`).

are there actually 217 keywords? Just wondering what the difference between that file and https://docs.swift.org/swift-book/documentation/the-swift-pr... (a mere 102 keywords)

That file is the compiler's list of reserved keywords, so some of them may not have been added to docs, or they're experimental/internal/...

I'm not 100% sure but I think the swift doc you linked is missing at least a dozen keywords so the truth probably lies in the middle

		Ah makes sense, personally I wouldn't consider reserved but unused words as keywords in the sense that you don't need to know them to read the language (even though they're keywords in some other technical sense). I was curious because I just tried counting number of keywords by language and it seemed surprisingly ambiguous/subjective/up to the language to say what's a "keyword" vs some type of core module. So my attempt (https://correctarity.com/keywords) probably has mistakes...
