Marin Todorov announces public beta of iOS Simulator second screen app called dataTile.
This app provides small additional screen which shows any log events from the app which developer considers relevant. App uses logs produced by Apple logging system, so if your app already uses those, no changes are needed in the app to support dataTile.
App is a good example of macOS SwiftUI app. It requires macOS Ventura though.
