Can someone explain the concept of an Anchor and Anchor.Source to me (from SwiftUI)?

I have a Modal view that seems to overlap the screen of my iPhoneX.This is DetailView.swift.import SwiftUI struct DetailView : View { @Binding var shouldDismiss : Bool var textData : String var image : UIImage? @Environment(.isPresented) private var isPresented var body: some View { VStack( alignment: .leading) { Button(action: { self.shouldDismiss.toggle() }) { Text(Close) }.font(.title) .foregroundColor(Color.secondary) .padding() Image(uiImage: image ?? UIImage()) .padding() Text(textData) .lineLimit(0) Spacer() } } }This is where the view is being pushed:ZStack { ... }.presentation(showDetails ? Modal(DetailView(shouldDismiss: $showDetails, textData: theTxtData, image: theImage), onDismiss:{ self.showDetails = false }) : nil)The DetailView overlaps on both sides of the screen. The text on the close Button is cut off (The C is not visible). Same goes for the image and the textData filed.

How to show a new SwiftUI View from a closure from a query?

I've stumbled through what documentation there is, and searched through the api's to the degree they are visible. It seems an 'obvious' add to be able to interact with sharing services in SwiftUI, without having to wrap an NSViewController to gain the ability to have a NSSharingServicePicker show itself. I'm hoping I'm overthinking this, and there's a simple solution.

The following code has two Buttons embedded in a VStack embedded in a Form. The action event for both buttons proceed when either button is tapped. I would expect them to act independently. Anyone have any ideas?import SwiftUIstruct Test : View { var body: some View { Form { VStack { Button(action: { print(Here 1) }) { Text(Clear image) } Button(action: { print(Here 2) }) { Text(Clear image) } } } }}

I am trying to bind a Picker, but it's not working. I create a BindableObject, an instance of Settings, add it to the environment using environmentObject() in SceneDelegate, and address it in the View using @EnvironmentObjectstruct ContentView : View { var favoriteFoods = [Tofu, Seitan, Nilla Wafers, Avocado Toast] @EnvironmentObject var settings : Settings // meanwhile, inside var body: some View ... Picker(selection: $settings.favoriteFoodChoice, label: Text(Favorite Food)){ ForEach(self.favoriteFoods.identified(by: .self)){ food in Text(food) } }Here's what my Settings looks like:class Settings : BindableObject { var didChange = PassthroughSubject<void,never>() var favoriteFoodChoice:Int { willSet { print(Favorite Food Choice will be (newValue)) didChange.send() print(Favorite Food Choice: (favoriteFoodChoice))// never changes when I select a different food. } didSet { print(Favorite Food Choice was (oldValue)) didChange.send() print(Favorite Food Choice: (favoriteFoodChoice))// never changes when I
