8. CI Caching untuk SPM

Lokasi 1: ~/Library/Developer/Xcode/DerivedData/<AppName>/SourcePackages/
  → Khusus untuk project ini, dalam DerivedData
  → Dibersihkan saat Clean Build Folder

Lokasi 2: ~/Library/Caches/org.swift.swiftpm/ (atau ~/.cache/org.swift.swiftpm/)
  → Global SPM cache, shared antar project
  → Lebih stabil untuk CI caching
