If you don't have one, create a file called

.gitignore

In your the root directory of your app and simply write

extension StringProtocol where Index == String.Index {
    func ranges<T: StringProtocol>(of substring: T, options: String.CompareOptions = [], locale: Locale? = nil) -> [Range<Index>] {
        var ranges: [Range<Index>] = []
        while let result = range(of: substring, options: options, range: (ranges.last?.upperBound ?? startIndex)..<endIndex, locale: locale) {
            ranges.append(result)
        }
        return ranges
    }
