Build Status

EffectiveSwift is a framework that makes you work more efficiently with Swift. It contains some extensions for Classes in iOS framework and some classes derived them or wrapped for them.


From CocoaPods

CocoaPods is a dependency manager for Objective-C/Swift, which automates and simplifies the process of using 3rd-party libraries like EffectiveSwift in your projects. First, add the following line to your Podfile:

pod 'EffectiveSwift'

If you want to use the latest features of EffectiveSwift use normal external source dependencies.

pod 'EffectiveSwift', :git => ''

This pulls from the master branch directly.

Take care that Swift project must add:


Second, install EffectiveSwift into your project:

pod install


  • Drag the EffectiveSwift/Extension and EffectiveSwift/Classes folders into your project.
  • Take care that modulemapFiles folder is added into your project folder. And set its path in Build Settings parameter Import Paths.
  • Add the libz dynamic library to your project.


(run this Xcode project. There are some sample in AppGenerate/ViewController)

Get a substring of String type

"abcde".substring(0..<3) // "abc"

Some other samples

// some samples of Extension for `String`
"hello".md5String // 5d41402abc4b2a76b9719d911017c592
"abcde".substring(0..<3) // "abc"
"url?serch=汉字".URLEncodedString // "url%3Fserch%3D%E6%B1%89%E5%AD%97"
"<a>超链接</a>".escapedHTMLString // "&quot;a&quot;超链接&quot;/a&quot;"

"".isHTTPURL() // true
"".entiretyMatchesRegex("^http(s)?:\/\/([\w-]+\.)+[\w-]+(\/[\w- .\/?%&=]*)?$") // true
"😀😂".containsEmoji() // true
"  content  ".trimming() // "content"

String(cString: "hello".cCharPointer) // "hello"
let h = Int8(cCharString: "h")!
let e = Int8(cCharString: "e")!
let l = Int8(cCharString: "l")!
let o = Int8(cCharString: "o")!
let cCharArray = [h, e, l, l, o]
String(cCharArray: cCharArray) // "hello"

// some samples of Extension for `Int`
UInt8(97).isEqualTo(char: "a") // true
UInt32(0xff10b2c3).uInt8Components // [0xff, 0x10, 0xb2, 0xc3]
Int8(cCharString: "A") // 65
let a: UInt32 = 0x41424345
a.isEqualTo(chars: "ABCE") // true

// some samples of Extension for `Double`
Double.random(range: 1.0..<1.9, precision: -4)

// some samples of Extension for `DispatchQueue`
DispatchQueue(label: "com.github.mikezone").isMainQueue // true
DispatchQueue.asyncOnMainQueue {
    // async execute code... in main queue

// some samples of Extension for `Date`
Date().subtractingDays(1).isYesterday // true"20170212", format: "yyyyMMdd")!.isSameWeekInChina("20170213", format: "yyyyMMdd")!) // false

// some samples of Extension for `Timer`
_ = Timer.scheduledTimer(withTimeInterval: 1, repeats: true, closure: {_ in

// some samples of Extension for `NSMutableAttributedString`
let attributedString = NSMutableAttributedString()

// some samples of Extension for `UIApplication`
UIApplication.shared.appBundleID // com.github.mikezone
UIApplication.shared.appVersion // 1.0

// some samples of Extension for `UIColor`
UIColor.lightText.alphaHexString // 99ffffff
UIColor(hexString: "333333")

// some samples of Extension for `UIControl`
UIButton().addBlock({ (sender) in
    print((sender as! UIButton).currentTitle ?? "")
}, for: .touchUpInside)

// some samples of Extension for `UIDevice`
UIDevice.current.isJailbroken // false
UIDevice.current.machineModelName // Simulator x64

// some samples of Extension for `UIFont`
let normalFont = UIFont.systemFont(ofSize: 12.0).normaling
normalFont?.isBold // false

// some samples of Extension for `UIGestureRecognizer`
_ = UIPinchGestureRecognizer({ pinch in
    if pinch.state == .began {


// some samples of Extension for `UIImage`
let image = UIImage(named: "xxx")
_ = image?.resizing(size: CGSize(width: 100, height: 150))
_ = image?.tinting(color:
_ = image?.rotatingLeft90


Use this framework like other Swift Module, you must add this line at top of your files:

import EffectiveSwift
