Does Swift provide a way to convert a raw String like this
"[\"John\",\"Anna\",\"Tom\"]"
to an Array of strings ([String])?
I've looked for a way to do it over StackOverflow, but in that specific way, I could not find an answer :/

On Swift 4 and later, use JSONDecoder:
let rawString = "[\"John\",\"Anna\",\"Tom\"]"
let jsonData = rawString.data(using: .utf8)!
let strings = try JSONDecoder().decode([String].self, from: jsonData)

Code Different answer is probably a recommended way to do it nowadays (Swift 4+).
For reference, here is a classic way to do the same, compatible with older Swift versions:
let rawString = "[\"John\",\"Anna\",\"Tom\"]"
let jsonData = rawString.data(using: .utf8)!
let strings = (try? JSONSerialization.jsonObject(with: jsonData, options: [])) as? [String] ?? []
According to Itai Ferber, JSONDecoder uses JSONSerialization under the hood, so it should do pretty much the same as Code Different answer.
