I have the following code:

let file = "/path/to/en.lproj/Localizable.strings"
let dec = PropertyListDecoder()
var f: PropertyListSerialization.PropertyListFormat = .openStep

do {
    //let data = strings.data(using: .utf8)!
    let data = try Data(contentsOf: URL(fileURLWithPath: file))
    let list = try dec.decode([String: String].self, from: data, format: &f)
    print("foramt:", f.rawValue)
    list.forEach { print($0.key, $0.value) }
} catch { print(error) }

It seems PropertyListDecoder can correctly decode .strings file format; detected format is openStep (value is 1). But I am note sure because I couldn't find any docs on PropertyListDecoder about .strings file.

Can anyone confirm this?

Does anyone know where I can find the specification of strings file format? Currently by pure observing, I believe the value part of key-value pair is very similar or same with C/JavaScript string syntax. Say, \n and " are escaped, but not sure if there are other specials.
