Swan's Quest, Chapter 1: Voices in the dark
Swift Playgrounds presents "Swan's Quest,” an interactive adventure in four chapters for all ages. In this chapter, our Hero must navigate a dark cave — and the only way to light the torches is to make them accessible.
Learn about VoiceOver and write interesting audio descriptions. You just might help our Hero find their way out… and get a clue for the next challenge.
Swan's Quest was created for Swift Playgrounds on iPad and Mac, combining frameworks and resources which power the educational experiences in many of our playgrounds, including Sonic Workshop, Sensor Arcade, and Augmented Reality. To learn more about building your own playgrounds, be sure to watch "Create Swift Playgrounds content for iPad and Mac".
And don't forget to stop by the Developer Forums and let us know what you thought of Swan's Quest.Recursos
