#!/usr/bin/env bash
# build-sim.sh — one-shot build + install + launch in the iOS simulator.
#
# Prereqs:
#   - Xcode installed, simulator available
#   - xcodegen (brew install xcodegen)
#   - bare-kit-pear added as an SPM dependency inside the generated Xcode
#     project (see ios-app/README.md)
#
# Run from project root:
#   ./ios-app/scripts/build-sim.sh
