A collection of UIKit, Foundation and other framework extensions that I usually use in my projects.

Contents

Utilities

There’s a bunch of utility properties accessible via the App struct.

Project name, version and build numbers:

print(App.bundleDisplayName)      // Your app's bundle display name
print(App.bundleName)             // Your app's bundle name
print(App.version)                // 1.0.0
print(App.buildNumber)            // 1
print(App.versionWithBuildNumber) // v1.0.0 (b1)

Runtime environment and configuration:

print(App.isDebug)              // true if Debug configuration is enabled
print(App.isRelease)            // true if Release configuration is enabled
print(App.isBeingTest)          // true if app is running in testing mode
print(App.isBeingUITested)      // true if app is running in UI testing mode
print(App.isRunningOnSimulator) // true if app is being run on the simulator
print(App.isRunningOnDevice)    // true if app is being run on a device

let delegate = App.delegete as! AppDelegate // A reference to the app delegate

Detect whether app has been launched before:

print(App.isFirstLaunch)                  // true if the app has never ran before on that device
print(App.isFirstLaunchForCurrentVersion) // true if the current version of the app has never run before

Array Extensions

Removes first occurence of an item from an array:

var array = [1, 2, 3, 4, 2]
array.removeObject(2) // [1, 3, 4, 2]

Remove all occurences of an item from an array:

var array = [1, 2, 3, 4, 2]
array.removeAllOccurencesOfObject(2) // [1, 3, 4]

Get all the indices where an object appears in the array

var array = ["iPhone", "iPhone", "iPad", "iPhone"]
print(array.indexesOf("iPhone")) // [0, 1, 3]
print(array.indicesOf("iPad")) // [2]

NSMutableAttributedString Extensions

Conveniently change the color of a substring which is part of an NSMutableAttributedString

let text = NSMutableAttributedString(string: "Hello I am a tomato!")
text.setColorForString("tomato", color: UIColor.redColor())

Dictionary Extensions

Check if a Dictionary contains a key:

let dict = ["Hodor": "dead", "John Snow": "resurrected", "Stanis Baratheon": "dead"]
dict.containsKey("Hodor") // true

UIColor Extensions

Convenience initialisers to work more easily with colors:

var blackColor = UIColor(hex: "#000", alpha: 1.0)     // black color
    blackColor = UIColor(hex: "#000000", alpha: 1.0)  // black color too

var whiteColor = UIColor(hex: "#FFF", alpha: 1.0)    // white color
    whiteColor = UIColor(hex: "#FFFFFF", alpha: 1.0) // white color too

let rgbWhiteColor = UIColor(r: 255.0, g: 255.0, b: 255.0)                        // white color using RGB values from 0 to 255
let rgbWhiteColorTransparent = UIColor(r: 255.0, g: 255.0, b: 255.0, alpha: 0.5) // alpha supported too

UIView Extensions

UIView size and origin:

let view = UIView()
print(view.x) // equal to view.frame.origin.x (also settable)
print(view.y) // equal to view.frame.origin.y (also settable)
print(view.width) // equal to view.frame.size.width (also settable)
print(view.height) // equal to view.frame.size.height (also settable)
print(view.leading // equal to view.frame.origin.x (also settable)
print(view.trailing) // equal to view.frame.origin.x + view.width (also settable)
print(view.top) // equal to view.frame.origin.y (also settable)
print(view.bottom) // equal to view.frame.origin.y + view.heigh (also settable)

Add borders and rounder corners to UIViews:

let view = UIView()
view.setCornerRadius(10.0) // changes view's corner raidus
view.addBorderWithWidth(1.0, andColor: UIColor.blackColor()) // Adds a 1px black border color
view.addTopBorderWithSize(1.0, andColor: UIColor.redColor()) // Adds a 1px red border on the top of the view
view.addBottomBorderWithSize(1.0, andColor: UIColor.greenColor()) // Adds a 1px green border color on the bottom of the view
view.addLeftBorderWithSize(1.0, andColor: UIColor.orangeColor()) // Adds a 1px orange color on the left of the view
view.addRightBorderWithSize(1.0, andColor: UIColor.yellowColor()) // Adds a 1px yellow color on the right of the view

Fade in/out a UIView:

let view = UIView()
view.alpha = 0
view.fadeIn() // Fades the view in
view.fadeOut() // Fades the view out

// Or more customizable
view.fadeIn(duration: 5, delay: 1) { animation in
    print("animation ended!")
}

UIViewController Extensions

Get a reference to app’s delegate:

override func viewDidLoad() {
  super.viewDidLoad()

  let appDelegate = myVC.appDelegate as! AppDelegate

}

Get a reference to the navigation bar if any:

override func viewDidLoad() {
  super.viewDidLoad()

  self.navigationBar.tintColor = UIColor.blackColor()

}

Get or set the navigation bar titleView:

override func viewDidLoad() {
  super.viewDidLoad()

  self.titleView = UIImageView(image: UIImage(named: "logo))

}

Easily present new view controllers or dismiss self:

override func viewDidLoad() {
  super.viewDidLoad()

  let myVC = MyViewController()

  present(myVC)  // Presents myVC modally
  self.dismiss() // Dismisses self

}

Example

To run the example project, clone the repo, and run pod install from the Example directory first.
