SwiftlyExt is a library that extends certain Swift standard types and classes using extension feature in the Swift language.

Requirements

  • iOS 9.0+ / macOS 10.11+ / tvOS 9.0+ / watchOS 2.0+
  • Xcode 8.0+
  • Swift 3.0+

Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

CocoaPods 1.1.0+ is required to build SwiftlyExt.

To integrate SwiftlyExt into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '10.0'
use_frameworks!

target '<Your Target Name>' do
    pod 'SwiftlyExt', '~> 1.3'
end

Then, run the following command:

$ pod install

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate SwiftlyExt into your Xcode project using Carthage, specify it in your Cartfile:

github "khoiln/SwiftlyExt" ~> 1.3

Run carthage update to build the framework and drag the built SwiftlyExt.framework into your Xcode project. U

Swift Package Manager

Adding SwiftlyExt as a dependency is as easy as adding it to the dependencies value of your Package.swift file.

dependencies: [
    .Package(url: "https://github.com/khoiln/SwiftlyExt.git", majorVersion: 1)
]

Note that the Swift Package Manager is still in early design and development, but SwiftlyExt does support its use on supported platforms.

Usage

There are many handy usages of SwiftlyExt, head over CocoaDocs for the comprehensive documentation.

We'll try to list some of the cool examples here.

Array Extensions

[😀,🤡,❤️,💋].sample() // Return a random element
// => 💋
[😀,🤡,❤️,💋].sampleSize(2) // Return n random elements
// => [🤡, 💋]
[1, 2, 3, 4, 5].dropWhile { $0 < 3 } //Drop elements that passes the predicate from the beginning to end
// => [3, 4, 5]
[1, 2, 3, 4, 5].dropWhile { $0 < 3 }.some {$0 % 2 == 0} //And YES you can use method chaining too 👍
// => true
[0, 11, 28, 10].every { $0 % 2 == 0 } //Check if all elements in the array passed the condition
// => false
[0, 11, 28, 10].some { $0 % 2 != 0 } //Check if one of the element passes the condition
// => true
[1, 2, 3, 4, 5].findLastIndex {$0 % 2 == 0} //Find index of the last number which predicate return true for.
// => 3 
[1, 2, 3, 4, 5].groupBy { $0 % 2 == 0 ? "even" : "odd"} //Group common elements from an array to a dictionary of [Hashable : [Element]]
// => ["even": [2,4], "odd": [1,3,5]]
// Any many more....

Date Extensions

let now = Date()
let tmr = now.date(byAddingDays: 1)
             .date(byAddingMinutes: 20) // You could also add year, month... and other time units

now.isBefore(tmr) 
// => true

now?.toString(format: "dd/MM/yyyy HH:mm:ss") // Return the string representation for a date.
// => "03/15/2017 14:34:22"

tmr.year == 2017 // Access time unit properties
tmr.hour == 14
tmr.minute == 54

String Extensions

"John Doe".initials // Return the initials of the String
// => "JD"
"[email protected]".isEmail // Email validation
// => true
"<p>💯</p>".between("<p>", "</p>") // Find the string between two string
// => "💯" 
"01/01/1970 00:34:22".date(format: "dd/MM/yyyy HH:mm:ss") // Return a date from current string
// => Date("01/01/1970 00:34:22")
"https://github.com/Swiftly".base64Encoded // Return base64encoded string
// => "aHR0cHM6Ly9naXRodWIuY29tL1N3aWZ0bHk="
"\n\n\n Swiftly    ".trimmed.reversed // Trim newline and spaces and reverse the string
// => "yltfiwS"
"Swiftly\t\nString\nTest".urlEncoded // URL Encoded
// => "Swiftly%09%0AString%0ATest"
"https%3A%2F%2Fgithub.com%2Fkhoiln%2FSwiftlyEXT".urlDecoded // URL Decoded
// => "https://github.com/khoiln/SwiftlyEXT"
// Any many more....

Int Extensions

1.upTo(3) { print($0) } 
// print 1, 2, 3
5.times { print("🐶") } // Run a block n times
// print 🐶 5 times
1234.digits() // Convert integer to array of digits
// => [1,2,3,4]
201.isIn(range: 200..<300) // Test whether a int is in a range
// => true
// And many more
