Create an Application
First, create a new project directory:
$ mkdir myFirstProject
Next, create a new Swift project using the Swift Package Manager.
$ cd myFirstProject
$ swift package init —-type executable
In Package.swift, add Kitura as a dependency for your project.
import PackageDescription
let package = Package(
name: "myFirstProject",
dependencies: [

Playgrounds: Mobile + Swift = BFF
The document outlines a presentation by Chris Bailey from the Swift @ IBM engineering team focused on various aspects of implementing Swift applications, including the backend for frontend (BFF) architecture and usage of the Star Wars API. It covers technical processes such as routing, server-side rendering, and application deployment, particularly using the Kitura framework. Additionally, it references the Mars Climate Orbiter and discusses trajectory calculations and related implications.
