#!/usr/bin/env bash
# build-ios-clean.sh — iOS clean rebuild ohne Festplatten-bloat
#
# Cleart vor jedem Build:
#   - Rebreak DerivedData (NICHT alle Projects, nur Rebreak-*)
#   - ios/build/ (Xcode workspace build output)
#
# Optional via env:
#   CLEAN_PODS=1   → auch ios/Pods nukern + pod install (langsamer, ~3min extra)
#   SKIP_BUILD=1   → nur cleanup, kein expo run:ios
#
# Usage:
#   ./scripts/build-ios-clean.sh                     # cleanup + simulator-build
#   ./scripts/build-ios-clean.sh --device            # cleanup + device-build
#   CLEAN_PODS=1 ./scripts/build-ios-clean.sh        # full reset
#   SKIP_BUILD=1 ./scripts/build-ios-clean.sh        # nur disk freigeben
