This code doesn't work. What should I do when it stops prematurely?
import Foundation
import AVFoundation
print("Hello, World!")
var synthesizer = AVSpeechSynthesizer()
let utterance = AVSpeechUtterance(string: "Hello World!")
utterance.voice = AVSpeechSynthesisVoice(identifier: "com.apple.speech.synthesis.voice.samantha.premium")
utterance.rate = 0.5
synthesizer.speak(utterance)
print("Done.")

The State variable that is used for the stiffness.@State private var stiffnessAmount: CGFloat = 1The Slider here sets the value, range, and step size.Slider(value: $stiffnessAmount, in: 1...10, step: 1)Text with modifier for the animation doesn't change its stiffnessAmount even though the Slider above: Text("Look here!")
.animation(
Animation.interpolatingSpring(stiffness: Double(stiffnessAmount), damping: 0)
.repeatCount(Int(animationCount), autoreverses: false)
)I changed the value using the Slider during runtime and then animation stiffness doesn't change.Why is it not working?

I have the following snippet of SwiftUI code using MapKit for iOS using MacOS Catalyst mode. The output of the code shows a large white box with the MapKit but that is not shown in the MacOS version using Cocoa with NS instead of UI. What is the problem?import SwiftUI
import MapKit
struct ContentView: View {
@State var date = Date()
var body: some View {
HStack {
NavigationView {
MapView()
.edgesIgnoringSafeArea(.all)
}
VStack(alignment: .leading) {
...
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
struct MapView: UIViewRepresentable {
typealias NSViewType = MKMapView
// 1.
func makeUIView(context: UIViewRepresentableContext<MapView>) -> MKMapView {
MKMapView(frame: .zero)
}
// 2.
func updateUIView(_ uiView: MKMapView, context: UIViewRepresentableContext<MapView>) {
// 3.
let location = CLLocationCoordinate2D(latitude: 30.0,
longitude: 0.0)
// 4.
let span = MKCoordinateSpan(latitudeDelta: 0.05, longitudeDelta: 0.05)
let region = MKCoordinateRegion(center: location, span: span)
uiView.setRegion(region, animated: true)
// 5.
let annotation = MKPointAnnotation()
annotation.coordinate = location
annotation.title = "Big Ben"
annotation.subtitle = "London"
uiView.addAnnotation(annotation)
}
}

What is the purpose of functions being first-class types in Swift 5+?Where does this usage occur and in what hypothetical scenarios?The following example from The Swift Programming Language book on iBooks as follows:func makeIncrementer() -> ((Int) -> Int) {
func addOne(number: Int) -> Int {
return 1 + number
}
return addOne
}
var increment = makeIncrementer()
increment(7)

The Timer on WatchKit doesn't execute the lblTimer.setText("(currentTime)") properly when it is there in the function called when the timer fires. What should I do to fix this problem? The label is just static and should be updated very often. Does the watchOS simulator have a bug?Also, I tried the Timer from watckKit and that didn't work either.Here's the sample code where the lblTimer.setText doesn't execute on the screen:@objc func fire()
{
print(countDown)
if (countDown <= 0.0) {
timer?.invalidate()
speechSynthesizer?.speak(AVSpeechUtterance(string: "You ran out of time! Next question!"))
countDown = 30.0
lblTimer.setText("30.0")
} else {
countDown -= 0.01
let numberOfPlaces = 2.0
let multiplier: Float = Float(pow(10.0, numberOfPlaces))
let num: Float = countDown
let rounded = round(num * multiplier) / multiplier
lblTimer.setText("Time: \(rounded)")
print(rounded)
}
}
