View range.swift
As of Swift 4 (Xcode 9), the Swift standard library provides methods to convert between Swift string ranges (Range<String.Index>) and NSString ranges (NSRange). Example:
let str = "a👿b🇩🇪c"
let r1 = str.range(of: "🇩🇪")!
// String range to NSRange:
let n1 = NSRange(r1, in: str)
print((str as NSString).substring(with: n1)) // 🇩🇪

// To write a pluggable function, you simply enclose it in a conditional tag to check if a function with that name has already been run:
if ( ! function_exists ( 'my_function' ) ) {
function my_function() {
// Contents of your function here.
Then when you come to write a function in your child theme which you want to override the one in the parent theme, you just give it the same name as the one in the parent theme:
