SwiftString3 1.0.11

You want to add pod 'SwiftString3', '~> 1.0' similar to the following to your Podfile:

target 'MyApp' do
  pod 'SwiftString3', '~> 1.0'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try SwiftString3

SwiftString3 1.0.11

By
Andrew Mayne, Jonathan Guthrie and Koji Murata

This repository was forked from https://github.com/iamjono/SwiftString. I made it usable with cocoapods.

SwiftString

SwiftString is a lightweight string extension for Swift 3. This library was motivated by having to search StackOverflow for common string operations, and wanting them to be in one place with test coverage.

Note the original client side Swift 2 repo can be found here: https://github.com/amayne/SwiftString

This Fork

This fork is intended as a server side utility.

It is Swift 3.0 and Swift Package Manager (SPM) ready.
Added sigificant test coverage
