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.
