This question belongs to View Building with SwiftUI , particularly the domain involving positioning and/or laying out a single SwiftUI view with standard views and modifiers . To place text on top of a shape such as a Capsule, SwiftUI uses the overlay modifier. Apple documents overlay as a view modifier that layers one view in front of another, which is exactly what is needed here: the text should appear on top of the blue capsule rather than beside or below it. The second blank must therefore be Text , because SwiftUI uses a Text view to display string content like " Great! " .

The completed code is:

struct ContentView: View {

var body: some View {

Capsule()

.fill(.blue)

.frame(width: 200.0, height: 100.0)

.overlay(

Text( " Great! " )

.font(.largeTitle)

)

}

}

This works because Capsule() creates the shape, .fill(.blue) gives it the blue color, .frame(width:height:) sets its size, and .overlay(...) places the Text( " Great! " ) directly above that shape. This is a standard SwiftUI composition pattern: build a base view, then apply modifiers to style it and layer additional content. In App Development with Swift objectives, this aligns with understanding standard views, modifiers, and layout techniques in SwiftUI.

This question is from Swift Programming Language , especially the domains for Optional types , safe and unsafe unwrapping , and control flow . The code uses the ternary conditional operator :

nextApplePhone.releaseDate != nil ? _____

In Swift, the ternary operator follows this structure:

condition ? valueIfTrue : valueIfFalse

So if nextApplePhone.releaseDate != nil is true, the expression must return the new release date. If it is false, it must keep lastReleaseDate unchanged. That means the missing part must be:

nextApplePhone.releaseDate! : lastReleaseDate

which is option D .

This works because nextApplePhone.releaseDate is declared as String?, so it is an optional. Once the condition confirms it is not nil, the code force-unwraps it with ! to access the underlying String value. If the optional is nil, the expression returns lastReleaseDate instead. Apple’s Swift documentation describes the ternary conditional operator as a shortcut for choosing one of two expressions based on a condition, and it explains that force unwrapping with ! accesses an optional’s wrapped value when you know it is not nil.

The other options are incorrect because they reverse the true/false logic, omit the needed unwrap, or contain invalid identifiers. Therefore, the correct completion is D .
