# Scaffolds the Xcode project for the iOS client via `tauri ios init`.
# Run from the repo root.
#
# The iOS host lives in `app/src-tauri-mobile/` (separate Cargo crate from
# the desktop host at `app/src-tauri/`) because the desktop crate is pinned
# to a vendored CEF Tauri fork that does not support iOS.
#
# After this script completes:
#   1. Open the generated .xcodeproj in Xcode and set your Development Team
#      (Signing & Capabilities tab).
#   2. Run `pnpm tauri:ios:dev` to start a hot-reload dev session.
