Example Usage

Easily get an object at a specified index:

var myArray = ["charmander","bulbasaur","squirtle"]
print(myArray.get(1)) // "bulbasaur"

Easily access a random element:

var myArray = ["charmander","bulbasaur","squirtle"]
print(myArray.random()) // bulbasaur or something else

Easily find the indexes of an object:

var myArray = ["charmander","bulbasaur","squirtle","charmander"]
print(myArray.indexesOf("charmander")) // [0,3]

Easily check if an array contains another array:

var myArray = ["charmander","bulbasaur","squirtle"]
print(myArray.containsArray(["charmander","bulbasaur"])) // true
print(myArray.containsArray(["string"])) // false

Block Objects These objects use completion blocks instead of selectors, taken from: CEMKit-Swift Easily initialize a BlockButton:

let button = BlockButton(x: 0, y: 0, w: 100, h: 100) { (sender) -> Void in
    print("Block button clicked!")
let button1 = BlockButton(x: 0, y: 0, w: 100, h: 100)
button1.addAction { (sender) -> Void in
    print("Block button clicked!")

// There are also BlockWebView, BlockTap, BlockPan, BlockSwipe, BlockPinch, BlockLongPress

Easily convert between different types:

var myCGFloat = myInt.toCGFloat
var myString = myInt.toString
var myDouble = myString.toDouble
var myInt = myDouble.toInt

Easily toggle it:

var myBool: Bool = true
print(myBool.toggle()) // false

Easily initialize your objects:

let myView = UIView(x: 0, y: 0, w: 100, h: 100)
print(myView.frame) // (0.0, 0.0, 100.0, 100.0)

Easily access your ViewController on top of your view stack:

ez.topMostViewController?.presentViewController(myAlertController, animated: true, completion: nil)
// topMostViewController is your rootViewController
// Intended for showing small VCs like UIAlertControllerstring.length, string.capitalizefirst, string.trim, string.isemail, 

Easily initialize your colors:

let myColor = UIColor(r: 100, g: 100, b: 100) // Default alpha is 1

Easily run block of codes after a certain delay:

Timer.runThisAfterDelay(seconds: 2) { () -> () in
    print("Prints this 2 seconds later in main queue")

Easily run code every seconds:

var count = 0
Timer.runThisEvery(seconds: 1) { (timer) -> Void in
    print("Will print every second")
    if count == 3 {
    count += 1

Easily access your projects version and build numbers:

print(ez.appVersion) // 0.3
print(ez.appBuild) // 7
print(ez.appVersionAndBuild) // v0.3(7)

Easily track screen shots:
ez.detectScreenShot { () -> () in
    print("User took a screen shot")
