ExAddingAndRemovingViews

This is a simple Swift application that demonstrates how to programmatically add and remove views in a UIViewController using NSLayoutConstraint and view.removeFromSuperview().

Features

• Programmatically adds and removes views from a UIViewController using NSLayoutConstraint and view.removeFromSuperview()
• Uses UISwitches to toggle the visibility of views

Purpose

The purpose of this application is to serve as a learning resource to programmatically add and remove views in a UIViewController. By demonstrating how to use NSLayoutConstraint and view.removeFromSuperview() triggered by UISwitches to toggle the visibility of views.

Usage

To use this application, simply clone the repository and open the project in Xcode. Run the application on a simulator or a physical device to see the views being added and removed using NSLayoutConstraint and view.removeFromSuperview(), and to toggle their visibility using UISwitches.

Deleting Main.storyboard steps

Do this to build your application completely programmatically. I do this so I can more easily get help from ChatGPT and other AI sources.

• create new project go to Info
• delete the Main storyboard file base name row
• In the same Info go to Application Scene Manifest > Scene Configuration > Window Application Session Role > Item 0
  • delete Storyboard Name row
• Edit the SceneDelegate method to display the MainVC

The last bullet point is necessary for building the app completely programmatically, as it allows you to set the root view controller of the window to be the MainVC without relying on a storyboard. This allows you to create and manage all of the views and layout of the app programmatically, rather than using a visual interface builder.
