Lately, I’ve been writing a lot about UIKit and I noticed I haven’t covered the delegate pattern. This pattern is not exclusive to UIKit but it’s quite used in this framework. In this post, we’ll dive into the Delegation Pattern, a fundamental design pattern in iOS development that helps in creating a well-structured codebase. What is the Delegation Pattern? The Delegation Pattern is a design pattern where one object (the delegator) hands off (or delegates) some of its responsibilities to another object (the delegate).

One common issue with programmatic UIKit development is dealing with the creation and configuration of UI objects. Configuring UI elements in our code can be cumbersome and hard to synchronize their behavior and style across several screens. By using the Builder Pattern, we can centralize the creation and configuration of these objects. This simplifies our codebase and decouples the creation of UI objects from our views. What is the Builder Pattern?

One of the standout features of SwiftUI is its reactive paradigm, which seamlessly updates views as data changes. This powerful approach isn’t confined to SwiftUI alone; it can also be harnessed in UIKit through the use of the Combine framework, and starting with iOS 17, through the new Observation framework. In this post, we’re going to explore using MVVM with UIKit, leveraging Combine to achieve reactive behaviors similar to SwiftUI. I hope you find this information useful and that it helps you improve the way you create and think about your applications.

In this entry, I’d like to explore the different ways we can interact with Xibs and Storyboards in our programmatic code. These files are present in many projects, so it’s important to understand the basics of how to work with them. Let’s start with some definitions! Definitions What are Storyboards Storyboards are like a big visual map in Xcode that lets you design your app’s screens. You can drag and drop things like buttons, labels, and images onto these screens to see how they’ll look.

Hello world, I’m back with a new entry on UIKit. In iOS 17 Apple added the ability to preview our views and ViewControllers using the SwiftUI canvas. This brings the possibility of faster programmatic UIKir programming. Let’s make a small project that illustrates how to leverage this new functionality and revising how we can create an app in UIKit 100% programmatically. 🚀 The app We will be coding an app that will ask for user information and then send it back to the main ViewController, this will showing us a simple way to pass information between views, a small introduction intro programmatic navigation and view reusability.
