  1. To add any third party swift package as a dependency in your swift package first you have to add the package url and requirements to the package dependency:

    .package(url: "https://github.com/IBM- 
Swift/BlueECC.git", from: "1.2.4")

    In the above snippet I have provided an example of version requirements, you can also have branch and commit requirements.

  2. Next, to use modules from 3rd party dependencies you have to specify the product name the module is included in and the package name in the target dependency:

    .product(name: "CryptorECC", package: "BlueECC")

    You can see what product contains what modules in the products section of package manifest of 3rd party libraries:

    products: [
    // Products define the executables and libraries produced by a package,
    // and make them visible to other packages.
    .library(
        // the product name
        name: "CryptorECC",
        // included modules in product
        targets: ["CryptorECC"]
    )
],

There are four ways to add the dependencies in Package.swift manifest file. Adding Alamofire library as example.

Using tag version

 // Syntax
.package(url: "Repository URL", from: "Version") 

// Example
.package(url: "https://github.com/Alamofire/Alamofire.git", from: "5.0.2")

Using branch name

// Syntax
.package(url: "Repository URL", .branch("branch-name"))

// Example
.package(url: "https://github.com/Alamofire/Alamofire.git", .branch("master"))

Using commit id

 // Syntax
 .package(url: "Repository URL",
                  .revision("commit-id"))

 // Example
 .package(url: "https://github.com/Alamofire/Alamofire.git",
                  .revision("eb67560abbc58e7d98e6e17daa5bd9376625f038"))

Using local repository

// Syntax
.package(path: "../Repository local path")

// Example
.package(path: "../Alamofire")

After that add this to your target section in Package.swift file: This is mandatory to add as this will make the module accessible to Swift PM, otherwise library/module will not accessible in Swift PM.

// Syntax
.target(
    name: "target-name",
    dependencies: ["dependency-name"]),

// Example
.target(
    name: "MyApp",
    dependencies: ["Alamofire"]),

Please find more techanical details about Swift PM here.

You will need the package URL, version number and the name of the package.

Add this to your manifest:

.package(url: 'the url of the package', from: 'version number')

After that add this to your target file:

.target(
    name: "target-name",
    dependencies: ["dependency-name"]),
