This is the biggest update since library launch! we're so excited ��</p> <h2>Requirements:</h2> <p>Xcode 8 (or later) with Swift 3. This library is made for iOS 8 or later, however most of the extensions should work on watchOS, tvOS, and macOS</p> <h2>Installation</h2> <h3>CocoaPods</h3> <p>CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:</p> <pre> <code class="language-swift">$ gem install cocoapods</code></pre> <p>To integrate SwifterSwift into your Xcode project using CocoaPods, specify it in your Podfile :</p> <pre> <code class="language-swift">source 'https://github.com/CocoaPods/Specs.git' platform :ios, '8.0' use_frameworks! target '<Your Target Name>' do pod 'SwifterSwift' end</code></pre> <p>Then, run the following command:</p> <pre> <code class="language-swift">$ pod install</code></pre> <h3>Carthage</h3> <p>Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.</p> <p>You can install Carthage with Homebrew using the following command:</p> <pre> <code class="language-swift">$ brew update $ brew install carthage</code></pre> <p>To integrate SwifterSwift into your Xcode project using Carthage, specify it in your Cartfile :</p> <pre> <code class="language-swift">github "omaralbeik/SwifterSwift" ~> 1.3.4</code></pre> <p>Run carthage update to build the framework and drag the built SwifterSwift.framework into your Xcode project.</p> <h3>Manually</h3> <p>Add theextensions folder to your Xcode project to use all extensions, or a specific extension.</p> <h2>How to contribute:</h2> <p>SwifterSwift is in its early stages, any feedback is appreciated and welcomed. Please refer to the contributing guidelines before participating.</p> <h2>List Of Extensions</h2> <ul> <li><a href="/misc/goto?guid=4959729313653801580" rel="nofollow,noindex">Array

<p>SwifterSwift is a library of over <strong>370 properties and methods</strong> , designed to extend Swift's functionality and productivity, staying faithful to the original API design guidelines of swift 3.</p> <p>Here are some examples:</p> <p>Array Extensions:</p> <pre> <code class="language-swift">// Remove duplicates from array [1, 2, 3, 1, 3].removeDuplicates() -> [1, 2, 3] // Return all
