Summary:
XCPShowView function no longer usable in Playgrounds, as it’s missing from the framework

Steps to Reproduce:


Expected Results:
Expected it to be there for use or an explanation of what to use instead

Actual Results:
Error” Use of unresolved identifier

Regression:
Worked fine for Cocoa Playgrounds in beta 2

Notes:
Example playground -

// Playground - noun: a place where people can play

import UIKit
import QuartzCore
import XCPlayground

var bezier = UIBezierPath()

let start = CGPoint(x: 0, y: 0)
let end = CGPoint(x: 100, y: 100)

let stepCount = 4.0

bezier.moveToPoint(start)

let grad = CGPoint(x: end.x - start.x, y: end.y - start.y)

let diff = CGPoint(x: grad.x / stepCount, y: grad.y / stepCount)

for i in 0..<stepCount {
  let point = CGPoint(x: i * diff.x, y: i * diff.y)
  let control = CGPoint(x: point.x - diff.x * 0.75 , y: point.y + diff.y * 2)
  bezier.addQuadCurveToPoint(point, controlPoint:control)
}

let shapeLayer = CAShapeLayer()

shapeLayer.path = bezier.CGPath

shapeLayer.strokeEnd = 0.1
shapeLayer.lineWidth = 1.0
shapeLayer.strokeColor = UIColor.blueColor().CGColor
shapeLayer.fillColor = UIColor.clearColor().CGColor

let view = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))

view.layer.addSublayer(shapeLayer)
