SwiftUI Input Controls and Layout

This unit focuses on composing layered layouts with ZStack and implementing common input controls in SwiftUI, including TextField, SecureField, Toggle, Slider, and Stepper. Students will practice state binding, control configuration, basic input validation, and accessibility considerations to prepare for more advanced state management and app navigation in later units.

Learning Objectives

• Analyze how ZStack arranges and overlays child views by constructing at least three interface variations that demonstrate different alignment, ordering, and spacing outcomes
• Apply @State bindings to TextField, SecureField, Toggle, Slider, and Stepper to capture and update model data, including configuring input types, ranges, and step values in a SwiftUI project
• Demonstrate secure input handling and basic validation by implementing SecureField for sensitive data, preventing inadvertent logging of secrets, and adding at least two validation checks for user-entered values
• Evaluate and customize control appearance and accessibility by adding labels, modifiers, and accessibility traits to Toggle, Slider, and Stepper so interfaces meet basic usability and WCAG-like criteria
