iOS

Application

let appName = Application.name             // CFBundleDisplayName : String
let appVersion = Application.version       // CFBundleShortVersionString : String
let appExecutable = Application.executable // CFBundleExecutable : String
let appBundle = Application.bundle         // CFBundleIdentifier : String
let appSchemes = Application.schemes       // CFBundleURLSchemes : [String]
let mainAppScheme = Application.mainScheme // CFBundleURLSchemes.first : String?

Gain easy access to main bundle information.

Screen

let pixelSize = Screen.pixelSize // CGSize(width: screenWidth * scale, height: screenHeight * scale)

Get the actual pixel information of the device screen.

Simulator

if !Simulator.isRunning {
  // add device specific operations here
}

To easily exclude operations from when you as a developer runs the application in the simulator, not subscribing to push notification or running analytics operations etc.

Keyboard Observer

Observe keyboard showing and hiding events, and handle it

let handler = BasicKeyboardHandler()
handler.show = { [weak self] height in
  // move text fields up
}

handler.hide = { [weak self] in
  // move text fields back to original position
}

keyboardObserver = KeyboardObserver(handler: handler)

Currently support

• BasicKeyboardHandler: basic UIView animation
• InsetKeyboardHandler: animate UIScrollView insets
• ConstraintKeyboardHandler: animate bottom layout constraint
• CustomKeyboardHandler: custom handling

iOS Extensions

UIView

.optimize()

let view = UIView.optimize
/*
  clipsToBounds = true
  layer.drawsAsynchronously = true
  opaque = true
*/

UIImage

+Rendering mode

image.original // imageWithRenderingMode(.AlwaysOriginal)
image.template // imageWithRenderingMode(.AlwaysTemplate)

Shared

SequenceType

let first: Int? = items.findFirst({ $0 > 10 })

Dates

Compare

if date1 < date2 {
  // do something
} else if date1 >= date2 {
  // do something else
}

Construct

let _ = 5.day
let _ = 3.week

Frame

let view = UIView()
view.width = 200
view.height = 200
view.x = 25
view.y = 25

print(view.width) // prints 200
print(view.height) // prints 200
print(view.x) // prints 25
print(view.y) // prints 25

Grand Central Dispatch

dispatch {
  // dispatch in main queue
}

dispatch(queue: .Background) {
  // dispatch in background queue
}

lazy var serialQueue = dispatch_queue_create("serialQueue", DISPATCH_QUEUE_SERIAL)
dispatch(queue: .Custom(serialQueue)) {
  // dispatch in a serial queue
}

Easy dispatching with grand central dispatch. Support all the regular global queues: Main, Interactive, Initiated, Utility, Background. And .Custom() for your own dispatch queues.

Localization

let string = localizedString("My Profile")
let formattedString = localizedString(key: "%d numbers", arguments: 10)

Swift access (pun intended) to NSLocalizedString, you will get more valid auto completion with this one, we promise.

Once

let once = Once()
once.run {
  // do something
}

once.run {
  // no effect
}

Operators

var url = NSURL(string: "hyper.no")!
url ?= NSURL(string: "\\/http")
// url is equal to hyper.no

The ?= only assigns values if the right is not nil.

Range

let acceptable = 200..<300
if acceptable.contains(response.statusCode) {
  // Status code is between 200 and 299.
}

Regex

if "[email protected]".isEmail() {
  // Is email
}

let stringNumber = "1984"
if stringNumber.isNumber() {
  // Is a number
}

if stringNumber.matches("^[0-9]+$") {
  // Is a number
}

Shared Extensions

+Queueable

struct Object: Queueable {

  func process() -> Bool { return true }
}

let myQueue = [Object(), Object()]
myQueue.processQueue()

Make your own processing queue with ease, just make your object conform the Queueable.

public protocol Queueable {
  func process() -> Bool
}

URLStringConvertible

let urlString = "https://hyper.no"
let url = urlString.url

Highly inspired by / borrowed from Alamofire's implementation of URLStringConvertible.

Core Foundation

let string = "hyper/oslo"
string.length // 10
string.truncate(5) // hyper...
string.split(/) // ["hyper", oslo]

if string.isPresent {
  // do something
}

if string.contains("hyper") {
  // found hyper
}

var dirtyString = "   hyper   "
print(dirtyString.trim()) // prints "hyper"

Just some extra sugar on top of String for getting the length, truncating, trimming or splitting a String.

isPresent is the opposite of isEmpty.

contains and be used to check if a string contains a word or pharse.

Swizzler

class Swizzled: NSObject {

  override class func initialize() {
    struct Static {
      static var token: dispatch_once_t = 0
    }

    if self !== Swizzled.self {
    return
  }

  dispatch_once(&Static.token) {
    Swizzler.swizzle("method", cls: self)
  }
}

  dynamic func method() -> Bool {
    return true
  }

  func swizzled_method() -> Bool {
    return false
  }
}

let object = Swizzled()
object.method() // false

Everyday we are swizzling, this use to be mundane, now it just Swiftling, we mean, super fast.

Then

let UIView().then {
  $0.backgroundColor = UIColor.blackColor()
}

This implementation is brought to you by @devxoul by his awesome Then repository.

Type Alias

public typealias JSONArray = [[String : AnyObject]]
public typealias JSONDictionary = [String : AnyObject]

UITesting

if UITesting.isRunning {
  // tests are running
} else {
  // everything is fine, move along
}

To easily include or exclude operations for when you are running UI tests.

UnitTesting

if UnitTesting.isRunning {
  // running test
}

func testPerformance() {
  let measurement = measure {
    // run operation
  }
}

Check if you are running UniTests and to measure performance.
