Introduction

Welcome to “Lesson 2: Implementing Data Passing Techniques in SwiftUI”. Building on the theory from the previous lesson on data flow, this lesson provides practical exercises to implement data passing in SwiftUI.

In this lesson, you’ll explore how data is dynamically passed from parent to child views using properties and Environment values. You’ll apply these techniques in the budget tracker app by implementing a List view to display financial entries and by using the SwiftUI environment to share theme colors.

Learning Objectives

In this lesson, you’ll learn how to:

• Implement data passing using properties and Environment values in SwiftUI.
• Apply data-passing techniques to create a simple, data-driven user interface.

By the end of this lesson, you’ll have hands-on experience with data-passing techniques in SwiftUI. It’s time to get started!
