Create an ApplicationFirst, create a new project directory

Next, create a new Swift project using the Swift Package Manager.

In Package.swift, add Kitura as a dependency for your project.

Create an ApplicationIn Sources/main.swift, add the following code.

Deploy an Application

Open your browser at http://localhost:8090

Compile and run your application:

Use Services
