As an exciting surprise Apple announced a new framework for iOS 15 to simultaneously join a video stream or custom experiences via a FaceTime call - this game is such a custom experience by playing "hangman" together.

The implementation is very rough but shows:

• how to set up and start a custom experience
• exchange data with participants
• draw a hangman (via PaintCode)

• you need at least two devices on iOS 15
• you need two Apple IDs set up on these device to initiate a FaceTime call between them
• install the app on both devices, launch it on one, then tap connect (top left)
• provide a guess word and start the game (top right)
• when somebody wants to guess either a character or the full word, tap on the wand and enter your guess
• at the end a small sound is played either for a successful/lost game

This is an experiment on top of the current iOS 15 beta - as this project is a test to explore Group Activities, it is not production ready and will contain bugs. Feel free to clone, tweak, hack around it.

• understanding session life cycle and data limits
• proper session teardown and recovery
• better state management
