How to Present Views in Full Screen Programmatically in iOS with Swift

When developing an iOS application, you might encounter the need to present views programmatically in full screen. This is particularly useful when you want to display information without any distractions from navigation bars or other elements. In this post, we’ll walk through how to present your view controllers in full screen correctly using Swift and Xcode.

Understanding the Problem

You might be working with various view controllers where each serves a specific function, such as editing a profile or changing a password. When you present these views based on user selection—like tapping on rows in a table view—you may find that some views do not display in full screen as expected.

This can happen for several reasons, including the presentation style not being set to full screen or the presence of a navigation controller that interferes with your layout.

How to Set Up Full Screen Presentation

To ensure that your view controllers present properly in full screen, you will need to make use of a UINavigationController and set the modal presentation style appropriately.

Step-by-Step Solution

Embed View Controllers in a UINavigationController:
Since you are navigating between different view controllers, it is best practice to embed them in a navigation controller. This gives you more control over how these view controllers are displayed.

Hide the Navigation Bar (if needed):
