A handy collection of more than 365 native Swift 3 extensions to boost your productivity.
v1.3 adds more than 90 new extensions making it the widest extensions library available online for Swift 3 with extensions for more than 36 type. This is the biggest update since library launch! we're so excited 🤓
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
CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:
$ gem install cocoapods
To integrate SwifterSwift into your Xcode project using CocoaPods, specify it in your Podfile
:
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!
target '<Your Target Name>' do
pod 'SwifterSwift'
end
Then, run the following command:
$ pod install
Add the extensions folder to your Xcode project to use all extensions, or a specific extension.

SwifterSwift is a library of over 365 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:
// Remove duplicates from 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 array
["h", "e", "l", "l", "o"].shuffled = ["e", "l", "o", "l", "h"]
// Return random item from array
[1, 2, 3, 4, 5].randomItem -> 3
// and many others!
// 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"
// and many others!
// Return count of substring in string
"hello world".count(of "o", caseSensitive: false) -> 2
// Return an array of strings separated by given string
"hello world".split(by: " ") -> ["hello", "world"]
// Return string with no spaces or new lines in beginning and end
"\n Hello ".trimmed -> "Hello"
// Return most common character in string
"swifterSwift is making swift more swifty".mostCommonCharacter -> "i"
// Returns CamelCase of string
"Some variable nAme".camelCased -> "someVariableName"
// Check if string is in valid email format
"omaralbeik@gmail.com".isEmail -> true
// Check if string contains at least one letter and one number
"123abc".isAlphaNumeric -> true
// Reverse string
"123abc".reverse() -> "cba321"
// Return latinized string
"Hèllö Wórld!".latinize() -> "Hello World!"
// Create random string of length
String.random(ofLength: 10) -> "AhEju28kNl"
// Check if string contains one or more instance of substring
"Hello World!".contain("o", caseSensitive: false) -> true
// Check if string contains one or more emojis
"string👨with😍emojis✊🏿".containEmoji -> true
// Convert string to numbers
"12.12".toDouble -> 12.12
// Encode and decode URLs
"it's easy to encode strings".urlEncoded -> "it's%20easy%20to%20encode%20strings"
"it's%20easy%20to%20encode%20strings".urlDecoded -> "it's easy to encode strings"
// Encode and decode base64
"Hello World!".base64Encoded -> "SGVsbG8gV29ybGQh"
"SGVsbG8gV29ybGQh".base64Decoded = "Hello World!"
// Truncate strings with a trailing
"This is a very long sentence".truncated(toLength: 14, trailing: = "...") -> "This is a very..."
// Repeat a string n times
"s" * 5 -> "sssss"
// NSString has never been easier
let boldString = "this is string".bold.colored(with: .red)
// and many others!
