Free Apple App-Development-with-Swift-Certified-User Exam Dumps Questions & Answers

Select the location to set this app to run on an iPhone 14 in the simulator.

Correct Answer:

Explanation:

This question belongs to Xcode Developer Tools , specifically the domain for building and running an app on the iOS simulator . In Xcode, the place where you choose whether the app runs on a simulator or a connected device is the run destination / scheme destination selector in the toolbar. This control appears near the top center of the Xcode window and displays the current destination, such as a simulator model or device target. To run the app on iPhone 14 , you click that selector and choose iPhone 14 from the available simulator list. Apple's Xcode documentation describes choosing a run destination before building and running the app in Simulator or on a device.
So, for the hotspot, the correct place is the device/simulator dropdown in the top toolbar , not the preview canvas controls, not the project navigator, and not the code editor. That selector determines where the app launches when you press Run.

Correct Answer:

NavigationLink, .sheet
Explanation:
This question falls under View Building with SwiftUI , specifically the domain covering multi-view apps with navigation stacks, links, and sheets . The first blank must be NavigationLink because SwiftUI uses a navigation link inside a NavigationStack to push or present a destination view as part of the navigation hierarchy. Apple's documentation states that people tap or click a NavigationLink to present a view inside a NavigationStack or NavigationSplitView. That matches the first code section, where tapping " Show Blue View " should navigate to BlueView().
The second blank must be .sheet because the code uses isPresented: $showRedView, which is the standard SwiftUI sheet modifier for modal presentation controlled by a Boolean binding. Apple documents sheet (isPresented:onDismiss:content:) as the modifier to use when you want to present a modal view when a Boolean becomes true. Since the button toggles showRedView, SwiftUI presents RedView() modally as a sheet.
So the completed structure is effectively:
NavigationLink( " Show Blue View " ) {
BlueView()
}
sheet(isPresented: $showRedView) {
RedView()
}
This directly aligns with SwiftUI navigation and modal presentation patterns in the App Development with Swift objective domains.
