# Clone dan edit package secara lokal sementara
# (tanpa mengubah Package.swift utama)
swift package edit swift-collections

# Sekarang swift-collections ada di ./checkouts/swift-collections/
# Edit file di sana, perubahan langsung terlihat

# Selesai editing — kembali ke versi dari Package.resolved
swift package unedit swift-collections
