iOS to visionOS: How to prepare your app for the future
summary
Migrates a UIKit iOS app (Crouton) to visionOS by making it compile, swapping opaque UI for UIVisualEffectView translucency, resizing interactive targets to 60pt and fixing hover shapes to circles, and minimizing third‑party dependencies when APIs like live activities, widgets, haptics and camera aren’t available. Converts scene delegate to the SwiftUI lifecycle to open volumetric windows, keeps a CloudKit share hook in the scene delegate to avoid a blank‑launch bug, implements timers as separate windows, adds a RealityKit size guide via regex to place real‑size overlays, and ships to the App Store day one.
