Check if a class conforms to a protocol instead of using respondsToSelector like in obj-c
import UIKit
// the protocol
protocol LayerManagerDelegate: class {
func doSomething()
}
// the class
class LayerManager {

Create a CGPath from an NSBezierPath in Swift. Great for CALayers for example.
// Adapted from Cocoa Drawing Guide's "Create a CGPathRef fram an NSBezierPath Object"
func CGPathFromNSBezierPath(nsPath: NSBezierPath) -> CGPath! {
if nsPath.elementCount == 0 {
return nil
}
let path = CGPathCreateMutable()
var didClosePath = false
