Swift Playgrounds 4.2 adds in Machine Learning lessons

On Wednesday, Apple rolled out an update to Swift Playgrounds, its free learn-to-code app available on iPad and macOS.

The iPad version of Swift Playgrounds has an improved interface with a customizable toolbar. Users can add their favorite items and new App Preview tabs allow users to quickly switch between multiple previews.

A new set of Machine Learning lessons teaches users to train an app to recognize images. Users can train the model with a rock, paper, scissors game.

Another lesson, "Laying Out Views," challenges users to match a UI mock-up in code.

In May, Apple updated Swift Playgrounds to version 4.1, which allowed users build Mac apps using SwiftUI.
