I'm trying to create a podspec for vapor/core. It already has a Swift Package Manager manifest file so I'm basing the podspec of of that.

Package.swift:

// swift-tools-version:4.0

import PackageDescription



let package = Package(

    name: "Core",

    products: [

        .library(name: "Async", targets: ["Async"]),

        .library(name: "Bits", targets: ["Bits"]),

        .library(name: "Core", targets: ["Core"]),

        .library(name: "COperatingSystem", targets: ["COperatingSystem"]),

        .library(name: "Debugging", targets: ["Debugging"]),

    ],

    dependencies: [

        /// Event-driven network application framework for high performance protocol servers & clients, non-blocking.

        .package(url: "https://github.com/apple/swift-nio.git", from: "1.8.0"),

    ],

    targets: [

        .target(name: "Async", dependencies: ["NIO"]),

        .testTarget(name: "AsyncTests", dependencies: ["Async"]),

        .target(name: "Bits", dependencies: ["Debugging", "NIO"]),

        .testTarget(name: "BitsTests", dependencies: ["Bits", "NIO"]),

        .target(name: "Core", dependencies: ["Async", "Bits", "COperatingSystem", "Debugging", "NIOFoundationCompat"]),

        .testTarget(name: "CoreTests", dependencies: ["Core"]),

        .target(name: "COperatingSystem"),

        .target(name: "Debugging"),

        .testTarget(name: "DebuggingTests", dependencies: ["Debugging"]),

    ]

)

I think what I want to do is create a subspec for each non-test target, although I'm not sure that's correct, so please correct me if that's wrong. This is what I've got for Core.podspec:

Pod::Spec.new do |s|



  s.name         = "Core"

  s.version      = "3.4.4"

  s.summary      = "🌎 Utility package containing tools for byte manipulation, Codable, OS APIs, and debugging."



  s.description  = <<-DESC

    Utility package containing tools for byte manipulation, Codable, OS APIs, and debugging.

  DESC



  s.homepage     = "https://github.com/vapor/core"

  s.license      = { :type => "MIT", :file => "LICENSE.txt" }



  s.author             = { "Tanner Nelson" => "" }



  s.ios.deployment_target = "10.0"



  s.source       = { :git => "https://github.com/twof/core.git", :branch => "master" }



  s.source_files = "Sources/**/*.swift"

  s.exclude_files = [

    'Pods/**'

  ]

  s.module_name = "Core"



  s.swift_version = "4.2"



  s.dependency 'SwiftNIO'



  s.subspec 'Debugging' do |debug|

      debug.source_files = 'Sources/Debugging/**/*.swift'

  end



  s.subspec 'Async' do |async|

      async.dependency 'SwiftNIO'



      async.source_files = 'Sources/Async/**/*.swift'

  end



  s.subspec 'Bits' do |bits|

      bits.dependency 'SwiftNIO'

      bits.dependency 'Core/Debugging'



      bits.source_files = 'Sources/Bits/**/*.swift'

  end



  s.subspec 'COperatingSystem' do |os|

      os.source_files = 'Sources/COperatingSystem/**/*.swift'

  end



  s.subspec 'Core' do |core|

      core.source_files = "Sources/Core/**/*.swift"



      core.dependency 'Core/Debugging'

      core.dependency 'Core/Async'

      core.dependency 'Core/Bits'

      core.dependency 'Core/COperatingSystem'

      core.dependency 'SwiftNIOFoundationCompat'

  end

end

However, the above fails linting with the following errors

 -> Core (3.4.4)

    - ERROR | [Core/Bits,Core/Core] xcodebuild: Returned an unsuccessful exit code.

    - ERROR | [Core/Bits,Core/Core] xcodebuild:  Core/Sources/Bits/BitsError.swift:1:8: error: no such module 'Debugging'

It seems like Core/Debugging is not being used as a dependency for Core/Bits and Core/Core, and I can't tell why that is. If it helps, you can find the full output of pod spec lint Core.podspec --verbose here.
