iOS 15 & Swift 5: Build a library with Swift Package Manager

Build a public interface for the onboarding kit with Swift Package Manager, letting clients initialize the framework, launch onboarding with a root view controller, and dismiss it when finished.

Learn to create and present a full-screen onboarding view controller using UIKit, integrate it into a Swift Package Manager onboarding kit, and configure modal transitions for a smooth launch.

Learn to build an onboarding flow using an onboarding view controller and onboarding kit with slides, images, captions, and a UI color customization in Swift.

Add two onboarding subviews in the onboarding view controller: a transition view with top bar, image, caption, and a bottom button container arranged by a vertical stack view.

Set up a transition view by building an animated bar view, a title view, and an image view. Use stack views and slides to determine dynamic bar counts and layout.

Implement a transition view timer for onboarding that starts on view appearance, with start/stop controls, using a dispatch timer every 3 seconds to show next.

Set up an animated bar view with two subviews—the background bar view and the foreground bar view—inject the bar color, apply constraints, and handle states to fill the bar, debugging.

Implement an animated foreground bar view that covers a background bar view, using a state machine with clear, animating, and fill states, driven by a UI view property animator.

Handle the get started button by dismissing the onboarding flow, stopping the onboarding animation to prevent retain cycles, and transition to the main view controller with a smooth animation.

Update the readme.md to provide clear installation guidance, including Swift Package Manager and manual install steps, and customize with your GitHub address, project name, and credits.

Extend the iOS library by adding a theme font option that lets users supply a font, falls back to the system font if unavailable, and passes the font through views.
