23. PackageDescription API Version 3 Package( name: String, pkgConfig: String? = nil, providers: [SystemPackageProvider]? = nil, targets: [Target] = [], dependencies: [Package.Dependency] = [], swiftLanguageVersions: [Int]? = nil, exclude: [String] = [] )
24. PackageDescription API Version 4 Package( name: String, pkgConfig: String? = nil, providers: [SystemPackageProvider]? = nil, products: [Product] = [], dependencies: [Dependency] = [], targets: [Target] = [], swiftLanguageVersions: [Int]? = nil )
