Example of hashing with swift: (The idea is to store Styles in a hash and see if performance goes up)

Fitting a circle Given 4 points. p1, p2, p3, p4

Reducing for-loops is a great way to maintain readability and maintain code modularity. “Data science” methods like map, flatMap, filter and reduce are awesome building blocks for functional programing in swift, but you can also build your own custom methods that do similar things.

Examples of singletons

class SingletonA {
    static let sharedInstance = SingletonA()
    init() {
        println("AAA");
    }
}

class TheOneAndOnlyKraken {
    static let sharedInstance = TheOneAndOnlyKraken()
    private init() {} //This prevents others from using the default '()' initializer for this class.
	func test(){
		print("hello world")
	}
}


let singleton = TheOneAndOnlyKraken.sharedInstance
singleton.test()

Another singleton example:

// Creating our Singleton

class Manager {
    // Declare our 'sharedI' property
    static let shared = SomeManager()

    // Set an initializer -
    // it will only be called once
    init() {
        print("SomeManager initialized")
    }

    // Add a test function
    func doSth() {
        print("I'm doing something")
    }
}

// The 'init' function will
// only be called the first time
Manager.shared.doSth()

CVDisplayLink is a timer object that allows your application to synchronize its drawing to the refresh rate of the display. ==It’s highly useful when you want to combine animation with user interactions==, something that is not easily handled by transitions or stock animations.

Researching hit-testing of sub views

Great method that asserts if an instance is of a class type or of a protocol type

Customize a window with any design and behavior, everything is also animatable.

My notes on implicit animation

When you want to assert if a digit is a digit i used to use a simple conditional back referencing pattern.

A graphics framework built on Quartz

NOTE: it does require that each class extends the same protocol and that they have similar init method

Drop this in playground and your on your way:

Extracting RGBA values from NSColor

**Casting Array to Array**

This is a great way to add context to “data container classes” as it is then easy to debug all the variables in the instance

My notes on the Equatable protocol in swift

Drop this code into any subclass of NSView, to enable the hand cursor
