To get going, you’ll really need to down load Xcode from the Mac Application Retail store. It’s free, and comes along with Swift and all one other applications you might want to abide by this tutorial.

ideal, but it will basically result in compiler mistakes. We’re telling Swift to pick a random element through the array and spot it into the selected property, but there’s no way for Swift To make certain there’s everything in that array – it could be empty, by which circumstance there’s no random aspect to return.
