[swift] How does String substring work in Swift

I created a simple extension for this (Swift 3)

extension String {
    func substring(location: Int, length: Int) -> String? {
        guard characters.count >= location + length else { return nil }
        let start = index(startIndex, offsetBy: location)
        let end = index(startIndex, offsetBy: location + length)
        return substring(with: start..<end)
    }
}
