When starting Xcode, use the menu bar to select File > New > Playground... or use the Shift⇧ + Option⌥ + CMD⌘ + N keyboard shortcut to create a new Playground. The following setup wizard will guide you through the steps of configuring the basic settings of the Playground.
Choose "Blank" and then click "Next" on bottom right. In the following step, choose a file name to save the Playground and click "Create". Xcode will create the Playground files and open the editor.
The Playground opens with a simple "Hello, playground" String in the main editor. If not open already, click on the Navigator icon to show the sidebar. The Playground has a Sources and a Resources folder in which additional files can be stored. The sources folder may contain other source code files, while the resources folder may contain any types of files, such as images, text files or in our case the machine learning model.
Now, let's see how to work with machine learning models inside Playground. Become a free member or log in to proceed.
