How to convert an NSRange to a Swift string index
Swift version: 5.0
Swift strings have changed in every release since the language was first announced, but even after so much change its older counterpart, NSRange, still appears in many UIKit APIs.
Fortunately, Swift 4 introduced a simple way to convert any NSRange into a regular Swift Range. For example, say you had the following string and range:
let input = "Hello, world"
let range = NSMakeRange(0, 10)To make that into a Swift Range instance you just need this single line of code:
let swiftRange = Range(range, in: input)SPONSOR Tired of wasting time debugging your Swift app?
