Meet `Substring`

🏵 Introduction

Substring is a tiny library allows you to substring without boilerplate, verbose and complex code.

The strings management of Swift is one of the most painful feature ever:

let string = "Substring API sucks!"
let start = string.index(string.startIndex, offsetBy: 1)
let end = string.index(string.startIndex, offsetBy: 6)
let substring = String(string[start..<end])

No! Stop it!

Now with this tiny library called Substring, you can simplly do this:

let substring = string[1..<6].string

Or this, if you prefer:

let substring = string.substring(in: 1..<6).string
