The Photon SDK includes a reference wallet app that documents how the components work together in a final product. You can try the demo app that showcases the seedless wallet UX that Photon enables.
The iOS demo app is available on Apple TestFlight here. Please note that the wallet runs on mainnet and uses real Bitcoin. Please don't put too many sats in while testing:
The git repo for the reference app can be found here. App developers are encouraged to fork the git repository or use it as a resource to help them build their own apps.
