What Will You Learn?

This course will take you through a carefully crafted journey to learn SwiftUI from scratch, introducing you to everything from basic views to advanced state management and animations. Here’s a breakdown of what you’ll cover in each session:

Session 1: Introduction to SwiftUI

We begin by introducing SwiftUI, Apple’s declarative UI framework, and why it’s changing the way apps are built. You’ll understand:

• The key differences between SwiftUI and UIKit.
• The benefits of its declarative nature.
• How SwiftUI supports cross-platform development across iOS, macOS, watchOS, and tvOS.
• A brief history of SwiftUI since its 2019 launch and why it’s poised to become the future of app development.

Session 2: Your First SwiftUI Project

In this session, you'll:

• Set up Xcode for SwiftUI development.
• Create your first SwiftUI project and understand the structure of a SwiftUI file.
• Break down the key components such as struct, View, and body, while exploring how Live Preview in Xcode allows you to see real-time changes.

Session 3: Working with Text and Images

Learn how to create engaging user interfaces by combining Text and Image views:

• Customize text with modifiers for font, color, and alignment.
• Add images using the Image view and explore SF Symbols.
• See how to seamlessly integrate text and images into your designs.

Session 4: Understanding Modifiers

Modifiers in SwiftUI allow you to customize views easily. You’ll learn:

• How to chain modifiers to create flexible, reusable views.
• Best practices for modifier order and usage to ensure efficient and visually appealing results.

Session 5: Working with Layouts – Stacks

Dive into the fundamental building blocks of SwiftUI layouts:

• Use VStack, HStack, and ZStack to organize your views.
• Manage spacing, alignment, and nesting for more sophisticated layouts.

Session 6: Building Complex Layouts with Grids and Groups

This session covers building complex layouts:

• Learn about LazyVGrid and LazyHGrid for creating dynamic grid layouts.
• Use ForEach to build repetitive or dynamic views, and Group for conditional content.

Session 7: Handling User Input – Buttons and TextFields

Learn how to handle user interaction:

• Implement Button and TextField views, customizing them for specific needs.
• Manage user input with @State and explore how binding connects data to your UI.

Session 8: Introduction to State Management

SwiftUI’s declarative nature relies heavily on state management:

• Discover the difference between @State, @Binding, and @EnvironmentObject.
• Implement a simple app to see how state drives UI changes in real-time.

Session 9: Navigation and NavigationView

Build multi-screen apps with ease:

• Use NavigationView and NavigationLink to navigate between views.
• Pass data between screens and customize the appearance of your navigation bar.

Session 10: Lists and Dynamic Content

Explore how to display dynamic collections of data:

• Use List and ForEach to create dynamic content.
• Customize list rows with your own views and handle selection events.

Session 11: Working with Pickers and Segmented Controls

Expand user interaction by:

• Adding Picker views and segmented controls to your UI.
• Bind picker values to your app's state and customize their appearance.

Session 12: Handling Alerts, Sheets, and ActionSheets

Learn how to handle modal views:

• Differentiate between Alert, Sheet, and ActionSheet.
• Present and manage these UI elements using closures and state variables.

Session 13: Animations and Transitions

Make your app more interactive and visually appealing by:

• Using both implicit and explicit animations.
• Adding smooth transitions between views and combining animations with state changes.

Session 14: Customizing Views with ViewBuilders and Custom Modifiers

Finally, we take your SwiftUI skills to the next level:

• Learn about ViewBuilder for creating reusable components.
• Create your own custom modifiers and implement best practices for building complex view hierarchies.

Hands-On Learning with Video Demonstrations

Each session is paired with in-depth video content, guiding you step-by-step through every concept:

• From setting up your first SwiftUI project to creating complex animations.
• Hands-on demonstrations allow you to see real-world use cases of SwiftUI in action.

Every lesson builds upon the last, ensuring you have a solid foundation before moving on to more advanced topics.

Why Take This Course?

SwiftUI Essentials is more than just an introduction to a new framework—it’s a complete toolkit to become proficient in SwiftUI. By the end of the course, you’ll be able to:

• Build beautiful, responsive apps that work across all Apple platforms.
• Streamline your development process with faster and more efficient tools.
