Installation

Swift Package Manager

You can use The Swift Package Manager to install SwifterSwift by adding the proper description to your Package.swift file:

import PackageDescription

let package = Package(
    name: "YOUR_PROJECT_NAME",
    targets: [],
    dependencies: [
        .Package(url: "https://github.com/SwifterSwift/SwifterSwift.git", versions: Version(1,4,0)..<Version(2, .max, .max)),
    ]
)

Note that the Swift Package Manager is still in early design and development, for more information checkout its GitHub Page

How cool is this?

SwifterSwift is a library of over 500 properties and methods, designed to extend Swift’s functionality and productivity, staying faithful to the original API design guidelines of Swift 3.

Here are some examples:

Array Extensions:

// Remove duplicates from an array
[1, 2, 3, 1, 3].removeDuplicates() -> [1, 2, 3]

// Return all indexes of specified item
["h", "e", "l", "l", "o"].indexes(of: "l") -> [2, 3]

// Shuffle an array
["h", "e", "l", "l", "o"].shuffled = ["e", "l", "o", "l", "h"]

// Return random item from an array
[1, 2, 3, 4, 5].randomItem -> 3

// and many others!

Date Extensions:

// Get and set components from date with ease
date.hour = 14

// Check if date is in today
Date().isInToday -> true

// Add 1 month to current date
Date().add(.month, value: 1)

// Return date at the beginning of current day
Date().beginning(of: .day)

// Return date at the end of current month
Date().end(of: .month)

// Check if date is in current calendar unit
Date().isInCurrent(.month) -> true

// Return iso8601 string for date
Date().iso8601String -> "2016-08-23T21:26:15.287Z"

// Create date from iso8601 string
let date = Date(iso8601String: "2016-08-23T21:26:15.287Z")

// Create date from DateComponents
let date = Date(year: 2016, month: 8, day: 15) // other components set to current
let date = Date(hour: 9, minute: 18, second: 1) // other components set to current

// Represent date as a string with ease
Date().dateString(ofStyle: .medium) -> "Aug 26, 2016"
Date().timeString(ofStyle: .short) -> "12:55 AM"
Date().dateTimeString() -> "Aug 26, 2016, 12:55:24 AM"
