// Package.resolved (auto-generated):
// Pins exact commit hash and version for every dependency
// Run "swift package update" to update pinned versions

// PackageA requires Logging 1.4.0
// PackageB requires Logging 1.5.0
// SPM resolves to 1.5.0 (satisfies both >= 1.x)
// Conflict: PackageA requires Logging 1.x, PackageB requires 2.x

// Force Logging 1.5.0 by declaring it directly:
.package(url: "https://github.com/apple/swift-log", exact: "1.5.0")
