What's the best practice to convert/wrap swift package to a cocoapods package?

I'v wrote a simple swift project that wraps a C library.

├── Package.swift
├── Sources
│   ├── CMyClient
│   │   ├── module.modulemap
│   │   └── my_client.h
│   └── MyClient
│        └── MyClient.swift
└── Tests
     └── MyClientTests
         └── MyClientTests.swift

and the content of Package.swift

import PackageDescription

let package = Package(
    name: "MyClient",
    products: [
        .library(
            name: "MyClient",
            targets: ["MyClient"]
        ),
    ],
    targets: [
        .systemLibrary(name: "CMyClient"),
        .target(
            name: "MyClient",
            dependencies: ["CMyClient"]
        )
        .testTarget(
            name: "MyClientTests",
            dependencies: ["MyClient"]
        )
    ]
)

when I test this project, I use the following (./Libs dir is for .a static library file)

swift test -Xlinker -L./Libs

For the integration reason, I should be able to provide this library in a cocoapods package format.

But I am very new to swift and it's eco system, especially cocoapods..

I tried to use pod lib create command to create a pod package project, but it generates too many things that confused me a lot, I don't event know where to put my code :(

I want to learn that if there is way to convert this to pod package with the minimum files and podspecs.

Thanks in advance.

Just add a MyClient.podspec file.
And manually fill its content.
