Question

How to extract substring between single quotation marks in Swift

Answer 1

import Foundation

func extractSubstring(from str: String) -> String {
    if let startPos = str.firstIndex(of: "'") {
        if let endPos = str[str.index(after: startPos)...].firstIndex(of: "'") {
            let range = str.index(after: startPos)..<endPos
            return String(str[range])
        }
    }
    return ""
}

let str = "Swift is a high-level 'general-purpose', compiled programming language"

let substr = extractSubstring(from: str)

print(substr)



/*
run:

general-purpose

*/
