-If the iOS build complains that MobileNebula.xcframework is stale or missing, run `./ensure-mobile-nebula.sh` from the repo root. It rebuilds the gomobile framework only when the Go code in `nebula/` changes, Xcode runs it automatically as a pre-build action on the Runner scheme.
+After a fresh checkout, run `./ensure-mobile-nebula.sh` once before building for iOS. Swift package resolution needs MobileNebula.xcframework to exist before the pre-build action that maintains it gets a chance to run. After that, Xcode keeps it fresh automatically, rebuilding only when the Go code in `nebula/` changes. If an iOS build ever complains the framework is stale or missing, run the script again by hand.
