SwiftUI Controls and Layouts

This unit covers fundamental SwiftUI input controls (TextField, SecureField, Toggle, Slider, Stepper) and the ZStack layout for composing layered interfaces. Students will practice state and binding management for interactive controls, implement basic input validation and secure entry, and prepare these components for inclusion in forms and navigation flows in subsequent units.

Learning Objectives

• Analyze when to use ZStack versus other stack types and compose layered interfaces by creating views that position and overlay content using ZStack and modifiers
• Apply SwiftUI state and binding patterns to implement interactive controls (TextField, SecureField, Toggle, Slider, Stepper) that read and update model data in sample views
• Demonstrate secure input handling and validation by implementing SecureField for credential entry, applying input constraints or format checks, and providing real-time UI feedback
• Evaluate accessibility and usability of input controls by testing keyboard types, labels, focus behavior, and accessibility modifiers, and implement improvements based on findings
