Adding Quotes in Swift

Question

Is there a straightforward way in Swift for adding quotation marks to a String? The quotation marks should localize properly (see https://en.wikipedia.org/w

Answer 1

Swift 4

Using the same logic, but with a modern and simple syntax.

extension String {
    static var quotes: (String, String) {
        guard
            let bQuote = Locale.current.quotationBeginDelimiter,
            let eQuote = Locale.current.quotationEndDelimiter
            else { return ("\"", "\"") }
        
        return (bQuote, eQuote)
    }
    
    var quoted: String {
        let (bQuote, eQuote) = String.quotes
        return bQuote + self + eQuote
    }
}

Then you can use it simply like this:

print("To be or not to be...".quoted)

Results

Locale   Output

 de      „To be or not to be...“
 en      “To be or not to be...”
 fr      «To be or not to be...»
 ja      「To be or not to be...」

Also, I advice you to read the whole Apple's Internationalization and Localization Guide

Answer 2

Using the information from http://nshipster.com/nslocale/:

let locale = NSLocale.currentLocale()
let qBegin = locale.objectForKey(NSLocaleQuotationBeginDelimiterKey) as? String ?? "\""
let qEnd = locale.objectForKey(NSLocaleQuotationEndDelimiterKey) as? String ?? "\""

let quote = qBegin + "To be or not to be..." + qEnd
print(quote)

Sample results:

Locale   Output

 de      „To be or not to be...“
 en      “To be or not to be...”
 fr      «To be or not to be...»
 ja      「To be or not to be...」

I don't know if the begin/end delimiter key can be undefined for a locale. In that case the above code would fall back to the normal double-quote ".

Answer 3

let quote = "\"To be or not to be...\""
println(quote)

output Will be: "To be or not to be..."
