Mandelbrot Set RenderingThis playground renders the Mandelbrot set by running code embedded within the playground’s Sources folder. You can explore the Sources folder by opening the Project Navigator (CMD+1) and clicking the triangle next to the playground file.

// Create a Mandelbrot set let m = MandelbrotView(frame: rect) Mandelbrot_Source…

// Create “Seahorse Valley” m.mandelbrotRect = newMandelbrotRect(points[“b”]!)

// Create Mandelbrot set within the Mandelbrot set m.mandelbrotRect = newMandelbrotRect(points[“e”]!)

case let x where x.hasSuffix(“pepper”): let vegetableComment = “Is it a spicy \(x)?”

default: let vegetableComment = “Everything tastes good in soup.”

}

Experiment: Try removing the default case. What error do you get?

Notice how let can be used in a pattern to assign the value that matched that part of a pattern to a constant.

After executing the code inside the switch case that matched, the program exits from the switch statement. Execution doesn’t continue to the next case, so there is no need to explicitly break out the switch at the end of each case’s code.

You use for-in to iterate over item in a dictionary by providing a pair of names to use for each key-value pair. Dictionaries are an unordered collection, so their keys and values are iterated over in an arbitrary order.

Is it a spicy red pepper?

let interesting Numbers = [ “Prime”: [2, 3, 5, 7, 11, 13], “Fibonacci”: [1, 1, 2, 3, 5, 8], “Square”; [1, 4, 9, 16, 25],

] var largest = 0 for (kind, numbers) in interestingNumbers {

for number in numbers { if number > largest {

largest = number
