	let dateFormatter = DateFormatter()
	dateFormatter.dateFormat = format
	return dateFormatter.string(from: self)
	}
	}
	// Example
	// Date().usingFormat("yyyy-MM-dd'T'HHmmss")

danielpi / OSTypedEnum.swift

Created March 27, 2017 13:29

Extension to AVCaptureVideoDataOutput and an enum to represent OSType CVPixelFormatType data

	extension AVCaptureVideoDataOutput {
	var availableVideoCVPixelFormatTypedEnums: [OSTypedEnum] {
	let availablePixelFormatDescriptions: Array<OSType> = self.availableVideoCVPixelFormatTypes as! Array<OSType>
	let availablePixelFormats: Array<OSTypedEnum> = availablePixelFormatDescriptions.map { OSTypedEnum(rawValue: $0)! }
	return availablePixelFormats
	}
	}

	enum OSTypedEnum: OSType {
	case monochrome1 = 1

My response to http://ericasadun.com/2016/01/11/make-this-swift-er-coordinate-distances/ Note I'm really just experimenting with a concept of encoding a calculations units into Swifts type system rather than actually suggesting that this is the best solution to the original problem. However this does have the advantage of taking care of conversi…

	import Cocoa

	public protocol Unit: CustomStringConvertible {
	var value: Double { get set }
	var baseSymbol: String { get }

	init(value: Double)
	}

	public extension Unit {

danielpi / MathematicsProtocol

Created April 9, 2015 22:25

A protocol to use when you want to write a generic function that can accept Ints, Floats or Doubles.

	protocol MathematicsProtocol: Equatable, Comparable, IntegerLiteralConvertible {
	init(_ value: Int)
	init(_ value: Float)
	init(_ value: Double)

	func +(lhs: Self, rhs: Self) -> Self
	func -(lhs: Self, rhs: Self) -> Self
	func * (lhs: Self, rhs: Self) -> Self
	func / (lhs: Self, rhs: Self) -> Self
	}
