So I've added swift-format as one of my dependencies to my own swift package so that I can use their lint swift package plugin. Here is my Package.swift: // swift-tools-version: 5.7 // The swift-tools-version declares the minimum version of Swift required to build this package. import PackageDescription let package = Package( name: "EssentialFeed", platforms: [ .iOS(.v16), .macOS(.v13), .macCatalyst(.v16), .tvOS(.v16), .watchOS(.v9) ], products: [ // Products define the executables and libraries a package produces, and make them visible to other packages. .library( name: "EssentialFeed", targets: ["EssentialFeed"]), .library( name: "EssentialFeedTestHelpers", targets: ["EssentialFeedTestHelpers"]), ], dependencies: [ .package(url: "https://github.com/apple/swift-format", .upToNextMajor(from: "0.50700.1")), ], targets: [ // Targets are the basic building blocks of a package. A target can define a module or a test suite. // Targets can depend on other targets in this package, and on products in packages this package depends on. .target( name: "EssentialFeed", dependencies: [], plugins: [ .plugin(name: "LintPlugin", package: "swift-format"), .plugin(name: "FormatPlugin", package: "swift-format"), ] ), .target( name: "EssentialFeedTestHelpers", dependencies: []), .testTarget( name: "EssentialFeedTests", dependencies: ["EssentialFeed", "EssentialFeedTestHelpers"]), .testTarget( name: "EssentialFeedAPIEndToEndTests", dependencies: ["EssentialFeed", "EssentialFeedTestHelpers"]), ] ) I get the following error when pulling this package: product 'LintPlugin' required by package 'essentialfeed' target 'EssentialFeed' not found in package 'swift-format'. But if you look at swift-format's Package.swift, you can see the plugins exist.
