Answer 1

In order to use asynchronous operations in an Xcode Playground, you need to set needsIndefiniteExecution to true.

Add this at the top of your code:

Swift 2

import XCPlayground
XCPlaygroundPage.currentPage.needsIndefiniteExecution = true

Swift 3

import PlaygroundSupport
PlaygroundPage.current.needsIndefiniteExecution = true
